INTRODUCTORY NOTE

A SKETCH of Darwin's life and some indication of the im-
portance of his work have been given in the edition of "The
Origin of Species" published in the Harvard Classics.

The text of the present volume shows without further com-
ment the nature of Darwin's labors and their results on this
momentous voyage. A few sentences gathered from his auto-
biography will, however, throw some additional light upon the
more personal aspects of the expedition.

"The Voyage of the 'Beagle' has been by far the most im-
portant event in my life, and has determined my whole career.
... / have always felt that I owe to the voyage the first real
training or education of my mind; I was led to attend closely
to several branches of natural history, and thus my powers of
observation were improved, though they were always fairly
developed. . . "

"The above various special studies were, however, of no im-
portance compared with the habit of energetic industry and of
concentrated attention to whatever I was engaged in, which I
then acquired. Everything about which I thought or read was
made to bear directly on what I had seen or was likely to see;
and this habit of mind was continued during the five years of
the voyage. I feel sure that it was this training which has en-
abled me to do whatever I have done in science."

"Looking backwards, I can now perceive how my love for
science gradually preponderated over every other taste. During
the first two years my old passion for shooting survived in nearly
full force, and I shot, myself, all the birds and animals for my
collection; but gradually I gave up my gun more and more, and
finally altogether, to my servant, as shooting interfered with my
work, more especially with making out the geological structure
of a country. I discovered, though unconsciously and insensibly,
that the pleasure of observing and reasoning was a much higher
one than that of skill and sport. . . ."

"As far as I can judge of myself, I worked to the utmost dur-
ing the voyage from the mere pleasure of investigation, and from
my strong desire to add a few facts to the great mass of facts
in Natural Science. But I was also ambitions to take a fair

6 INTRODUCTION

place among scientific men, — whether more ambitious or less so
than most of my fellow-workers, I can form no opinion." — (Life
and Letters, I. pp. 61-65.)

Even if the Journal of the voyage were not one of the most
' interesting and informing of books, this statement by its author
of the importance of the expedition in making possible his later
epoch-making generalizations would give it a distinctive place in
the literature of science. But its amazing wealth of informa-
tion and its unconsciously painted picture of disinterested zeal
in the search for scientific truth have made it for intrinsic rea-
sons a classic in its kind.

TO
CHARLES LYELL, ESQ., F.R.S.

THIS SECOND EDITION IS DEDICATED WITH GRATEFUL PLEASURE, AS
AN ACKNOWLEDGMENT THAT THE CHIEF PART OF WHATEVER
SCIENTIFIC MERIT THIS JOURNAL AND THE OTHER WORKS OF
THE AUTHOR MAY POSSESS, HAS BEEN DERIVED FROM STUDYING
THE WELL-KNOWN AND ADMIRABLE

PRINCIPLES OF GEOLOGY

PREFACE

I HAVE stated in the preface to the first Edition of this work,
and in the Zoology of the Voyage of the Beagle, that it was in
consequence of a wish expressed by Captain Fitz Roy, of having
some scientific person on board, accompanied by an offer from
him of giving up part of his own accommodations, that I volun-
teered my services, which received, through the kindness of the
hydrographer, Captain Beaufort, the sanction of the Lords of
the Admiralty. As I feel that the opportunities which I enjoyed
of studying the Natural History of the different countries we
visited, have been wholly due to Captain Fitz Roy, I hope I may
here be permitted to repeat my expression of gratitude to him;
and to add that, during the five years we were together, I re-
ceived from him the most cordial friendship and steady assist-
ance. Both to Captain Fitz Roy and to all the Officers of the
Beagle1 I shall ever feel most thankful for the undeviating kind-
ness with which I was treated during our long voyage.

This volume contains, in the form of a Journal, a history of
our voyage, and a sketch of those observations in Natural History
and Geology, which I think will possess some interest for the
general reader. I have in this edition largely condensed and
corrected some parts, and have added a little to others, in order
to render the volume more fitted for popular reading ; but I trust
that naturalists will remember, that they must refer for details
to the larger publications which comprise the scientific results
of the Expedition. The Zoology of the Voyage of the Beagle
includes an account of the Fossil Mammalia, by Professor Owen ;
of the Living Mammalia, by Mr. Waterhouse ; of the Birds, by
Mr. Gould; of the Fish, by the Rev. L. Jenyns; and of the Rep-
tiles, by Mr. Bell. I have appended to the descriptions of each
species an account of its habits and range. These works, which

I 1 must take this opportunity of returning my sincere thanks to Mr.
Bynoe, the surgeon of the Beagle, for his very kind attention to me when
I was ill at Valparaiso.

10 PREFACE

I owe to the high talents and disinterested zeal of the above
distinguished authors, could not have been undertaken, had it not
been for the liberality of the Lords Commissioners of Her Maj-
esty's Treasury, who, through the representation of the Right
Honourable the Chancellor of the Exchequer, have been pleased
to grant a sum of one thousand pounds towards defraying part
of the expenses of publication.

I have myself published separate volumes on the ' Structure
and Distribution of Coral Reefs ;' on the ' Volcanic Islands
visited during the Voyage of the Beagle;' and on the 'Geology
of South America.' The sixth volume of the ' Geological Trans-
actions ' contains two papers of mine' on the Erratic Boulders
and Volcanic Phenomena of South America. Messrs. Water-
house, Walker, Newman, and White, have published several able
papers on the Insects which were collected, and I trust that many
others will hereafter follow. The plants from the southern parts
of America will be given by Dr. J. Hooker, in his great work on
the Botany of the Southern Hemisphere. The Flora of the
Galapagos Archipelago is the subject of a separate memoir by
him, in the 'Linnean Transactions.' The Reverend Professor
Henslow has published a list of the plants collected by me at the
Keeling Islands; and the Reverend J. M. Berkeley has described
my cryptogamic plants.

I shall have the pleasure of acknowledging the great assistance
which I have received from several other naturalists, in the
course of this and my other works; but I must be here allowed
to return my most sincere thanks to the Reverend Professor
Henslow, who, when I was an undergraduate at Cambridge, was
one chief means of giving me a taste for Natural History, —
who, during my absence, took charge of the collections I sent
home, and by his correspondence directed my endeavours, — and
who, since my return, has constantly rendered me every assist-
ance which the kindest friend could offer.

A FTER having been twice driven back by heavy south-
L\ western gales, Her Majesty's ship Beagle, a ten-gun
wLJL. brig, under the command of Captain Fitz Roy, R. N.,
sailed from Devonport on the 27th of December, 1831. The
object of the expedition was to complete the survey of Pata-
gonia and Tierra del Fuego, commenced under Captain King
in 1826 to 1830 — to survey the shores of Chile, Peru, and
of some islands in the Pacific — and to carry a chain of
chronometrical measurements round the World. On the 6th
of January we reached Teneriffe, but were prevented land-
ing, by fears of our bringing the cholera : the next morning
we saw the sun rise behind the rugged outline of the Grand
Canary island, and suddenly illuminate the Peak of Teneriffe,
whilst the lower parts were veiled in fleecy clouds. This
was the first of many delightful days never to be forgotten.
On the i6th of January, 1832, we anchored at Porto Praya,
in St. Jago, the chief island of the Cape de Verd archipelago.

The neighbourhood of Porto Praya, viewed from the sea,
wears a desolate aspect. The volcanic fires of a past age,
and the scorching heat of a tropical sun, have in most places
rendered the soil unfit for vegetation. The country rises in
successive steps of table-land, interspersed with some trun-
cate conical hills, and the horizon is bounded by an irregular
chain of more lofty mountains. The scene, as beheld through

12 CHARLES DARWIN

the hazy atmosphere of this climate, is one of great interest;
if, indeed, a person, fresh from sea, and who has just
walked, for the first time, in a grove of cocoa-nut trees, can
be a judge of anything but his own happiness. The island
would generally be considered as very uninteresting; but to
anyone accustomed only to an English landscape, the novel
aspect of an utterly sterile land possesses a grandeur which
more vegetation might spoil. A single green leaf can
scarcely be discovered over wide tracts of the lava plains;
yet flocks of goats, together with a few cows, contrive to
exist. It rains very seldom, but during a short portion of
the year heavy torrents fall, and immediately afterwards a
light vegetation springs out of every crevice. This soon
withers; and upon such naturally formed hay the animals
live. It had not now rained for an entire year. When the
island was discovered, the immediate neighbourhood of
Porto Praya was clothed with trees,1 the reckless destruc-
tion of which has caused here, as at St. Helena, and at
some of the Canary islands, almost entire sterility. The
broad, flat-bottomed valleys, many of which serve during a
few days only in the season as water-courses, are clothed
with thickets of leafless bushes. Few living creatures inhabit
these valleys. The commonest bird is a kingfisher (Dacelo
lagoensis), which tamely sits on the branches of the castor-
oil plant, and thence darts on grasshoppers and lizards. It
is brightly coloured, but not so beautiful as the European
species : in its flight, manners, and place of habitation, which
is generally in the driest valley, there is also a wide dif-
ference.

One day, two of the officers and myself rode to Ribeira
Grande, a village a few miles eastward of Porto Praya. Un-
til we reached the valley of St. Martin, the country presented
its usual dull brown appearance; but here, a very small rill
of water produces a most refreshing margin of luxuriant
vegetation. In the course of an hour we arrived at Ribeira
Grande, and were surprised at the sight of a large ruined
fort and cathedral. This little town, before its harbour was
filled up, was the principal place in the island: it now pre-

*I state this on the authority of Dr. E. Dieffenbach, in his German
translation of the first edition of this Journal.

THE VOYAGE OF THE BEAGLE 13

sents a melancholy, but very picturesque appearance. Hav-
ing procured a black Padre for a guide, and a Spaniard who
had served in the Peninsular war as an interpreter, we vis-
ited a collection of buildings, of which an ancient church
formed the principal part. It is here the governors and
captain-generals of the islands have been buried. Some of
the tombstones recorded dates of the sixteenth century.*
The heraldic ornaments were the only things in this retired
place that reminded us of Europe. The church or chapel
formed one side of a quadrangle, in the middle of which a
large clump of bananas were growing. On another side
was a hospital, containing about a dozen miserable-looking
inmates.

We returned to the Venda to eat our dinners. A consid-
erable number of men, women, and children, all as black as
jet, collected to watch us. Our companions were extremely
merry; and everything we said or did was followed by their
hearty laughter. Before leaving the town we visited the
cathedral. It does not appear so rich as the smaller church,
but boasts of a little organ, which sent forth singularly in-
harmonious cries. We presented the black priest with a few
shillings, and the Spaniard, patting him on the head, said,
with much candour, he thought his colour made no great
difference. We then returned, as fast as the ponies would
go, to Porto Praya.

Another day we rode to the village of St. Domingo, situ-
ated near the centre of the island. On a small plain which
we crossed, a few stunted acacias were growing; their tops
had been bent by the steady trade-wind, in a singular man-
ner— some of them even at right angles to their trunks. The
direction of the branches was exactly N. E. by N., and S. W.
by S., and these natural vanes must indicate the prevailing
direction of the force of the trade-wind. The travelling had
made so little impression on the barren soil, that we here
missed our track, and took that to Fuentes. This we did
not find out till we arrived there; and we were afterwards
glad of our mistake. Fuentes is a pretty village, with a small
stream; and everything appeared to prosper well, excepting,

2 The Cape de Verd Islands were discovered in 1449. There was a
tombstone of a bishop with the date of 1571; and a crest of a hand and
dagger, dated 1497.

14 CHARLES DARWIN

indeed, that which ought to do so most — its inhabitants.
The black children, completely naked, and looking very
wretched, were carrying bundles of firewood half as big as
their own bodies.

Near Fuentes we saw a large flock of guinea-fowl —
probably fifty or sixty in number. They were extremely
wary, and could not be approached. They avoided us, like
partridges on a rainy day in September, running with their
heads cocked up; and if pursued, they readily took to the
wing.

The scenery of St. Domingo possesses a beauty totally
unexpected, from the prevalent gloomy character of the rest
of the island. The village is situated at the bottom of a
valley, bounded by lofty and jagged walls of stratified lava.
The black rocks afford a most striking contrast with the
bright green vegetation, which follows the banks of a little
stream of clear water. It happened to be a grand feast-day,
and the village was full of people. On our return we over-
took a party of about twenty young black girls, dressed in
excellent taste ; their black skins and snow-white linen being
set off by coloured turbans and large shawls. As soon as
we approached near, they suddenly all turned round, and
covering the path with their shawls, sung with great energy
a wild song, beating time with their hands upon their legs.
We threw them some vintems, which were received with
screams of laughter, and we left them redoubling the noise
of their song.

One morning the view was singularly clear; the distant
mountains being projected with the sharpest outline on a
heavy bank of dark blue clouds. Judging from the appear-
ance, and from similar cases in England, I supposed that the
air was saturated with moisture. The fact, however, turned
out quite the contrary. The hygrometer gave a difference
of 29.6 degrees, between the temperature of the air, and the
point at which dew was precipitated. This difference was
nearly double that which I had observed on the previous
mornings. This unusual degree of atmospheric dryness was
accompanied by continual flashes of lightning. Is it not an
uncommon case, thus to find a remarkable degree of aerial
transparency with such a state of weather?

THE VOYAGE OF THE BEAGLE IS

Generally the atmosphere is hazy; and this is caused by
the falling of impalpably fine dust, which was found to have
slightly injured the astronomical instruments. The morning
before we anchored at Porto Praya, I collected a little packet
of this brown-coloured fine dust, which appeared to have
been filtered from the wind by the gauze of the vane at the
masthead. Mr. Lyell has also given me four packets of dust
which fell on a vessel a few hundred miles northward of
these islands. Professor Ehrenberg* finds that this dust con-
sists in great part of infusoria with siliceous shields, and of
the siliceous tissue of plants. In five little packets which I
sent him, he has ascertained no less than sixty-seven dif-
ferent organic forms ! The infusoria, with the exception of
two marine species, are all inhabitants of fresh-water. 1
have found no less than fifteen different accounts of dust
having fallen on vessels when far out in the Atlantic. From
the direction of the wind whenever it has fallen, and from
its having always fallen during those months when the har-
mattan is known to raise clouds of dust high into the atmos-
phere, we may feel sure that it all comes from Africa. It
is, however, a very singular fact, that, although Professor
Ehrenberg knows many species of infusoria peculiar to
Africa, he finds none of these in the dust which I sent him.
On the other hand, he finds in it two species which hitherto
he knows as living only in South America. The dust falls
in such quantities as to dirty everything on board, and to
hurt people's eyes; vessels even have run on shore owing to
the obscurity of the atmosphere. It has often fallen on
ships when several hundred, and even more than a thousand
miles from the coast of Africa, and at points sixteen hun-
dred miles distant in a north and south direction. In some
dust which was collected on a vessel three hundred miles
from the land, I was much surprised to find particles of
stone above the thousandth of an inch square, mixed with
finer matter. After this fact one need not be surprised
at the diffusion of the far lighter and smaller sporules of
cryptogamic plants.

8 1 must take this opportunity of acknowledging the great kindness
with which this illustrious naturalist has examined many of my specimens.
I have sent (June, 1845) a full account of the falling of this dust to the
Geological Society.

16 CHARLES DARWIN

The geology of this island is the most interesting part of
its natural history. On entering the harbour, a perfectly
horizontal white band, in the face of the sea cliff, may be seen
running for some miles along the coast, and at the height of
about forty-five feet above the water. Upon examination,
this white stratum is found to consist of calcareous matter,
with numerous shells embedded, most or all of which now
exist on the neighbouring coast. It rests on ancient volcanic
rocks, and has been covered by a stream of basalt, which
must have entered the sea when the white shelly bed was
lying at the bottom. It is interesting to trace the changes,
produced by the heat of the overlying lava, on the friable
mass, which in parts has been converted into a crystalline
limestone, and in other parts into a compact spotted stone.
Where the lime has been caught up by the scoriaceous frag-
ments of the lower surface of the stream, it is converted into
groups of beautifully radiated fibres resembling arragonite.
The beds of lava rise in successive gently-sloping plains,
towards the interior, whence the deluges of melted stone
have originally proceeded. Within historical times, no signs
of volcanic activity have, I believe, been manifested in any
part of St. Jago. Even the form of a crater can but rarely
be discovered on the summits of the many red cindery hills;
yet the more recent streams can be distinguished on the
coast, forming lines of cliffs of less height, but stretching
out in advance of those belonging to an older series: the
height of the cliffs thus affording a rude measure of the age
of the streams.

During our stay, I observed the habits of some marine
animals. A large Aplysia is very common. This sea-slug
is about five inches long; and is of a dirty yellowish colour,
veined with purple. On each side of the lower surface, or
foot, there is a broad membrane, which appears sometimes
to act as a ventilator, in causing a current of water to flow
over the dorsal branchiae or lungs. It feeds on the delicate
sea-weeds which grow among the stones in muddy and shal-
low water; and I found in its stomach several small pebbles,
as in the gizzard of a bird. This slug, when disturbed, emits
a very fine purplish-red fluid, which stains the water for the
space of a foot around. Besides this means of defence, an

THE VOYAGE OF THE BEAGLE 17

acrid secretion, which is spread over its body, causes a
sharp, stinging sensation, similar to that produced by the
Physalia, or Portuguese man-of-war.

I v/as much interested, on several occasions, by watching
the habits of an Octopus, or cuttle-fish. Although common
in the pools of water left by the retiring tide, these animals
were not easily caught. By means of their long arms and
suckers, they could drag their bodies into very narrow crev-
ices; and when thus fixed, it required great force to remove
them. At other times they darted tail first, with the rapidity
of an arrow, from one side of the pool to the other, at the
same instant discolouring the water with a dark chestnut-
brown ink. These animals also escape detection by a very
extraordinary, chameleon-like power of changing their col-
our. They appear to vary their tints according to the nature
of the ground over which they pass : when in deep water,
their general shade was brownish purple, but when placed on
the land, or in shallow water, this dark tint changed into one
of a yellowish green. The colour, examined more carefully,
was a French grey, with numerous minute spots of bright
yellow: the former of these varied in intensity; the latter
entirely disappeared and appeared again by turns. These
changes were effected in such a manner, that clouds, varying
in tint between a hyacinth red and a chestnut-brown,4 were
continually passing over the body. Any part, being subjected
to a slight shock of galvanism, became almost black: a simi-
lar effect, but in a less degree, was produced by scratching
the skin with a needle. These clouds, or blushes as they may
be called, are said to be produced by the alternate expansion
and contraction of minute vesicles containing variously
coloured fluids.5

This cuttle-fish displayed its chameleon-like power both
during the act of swimming and whilst remaining stationary
at the bottom. I was much amused by the various arts to
escape detection used by one individual, which seemed fully
aware that I was watching it. Remaining for a time motion-
less, it would then stealthily advance an inch or two, like a
cat after a mouse; sometimes changing its colour: it thus

proceeded, till having gained a deeper part, it darted away,
leaving a dusky train of ink to hide the hole into which it
had crawled.

While looking for marine animals, with my head about
two feet above the rocky shore, I was more than once saluted
by a jet of water, accompanied by a slight grating noise. At
first I could not think what it was, but afterwards I found
out that it was this cuttle-fish, which, though concealed in a
hole, thus often led me to its discovery. That it possesses
the power of ejecting water there is no doubt, and it appeared
to me that it could certainly take good aim by directing the
tube or siphon on the under side of its body. From the diffi-
culty which these animals have in carrying their heads, they
cannot crawl with ease when placed on the ground. I
observed that one which I kept in the cabin was slightly
phosphorescent in the dark.

ST. PAUL'S ROCKS. — In crossing the Atlantic we hove-to,
during the morning of February i6th, close to the island of
St. Paul's. This cluster of rocks is situated in o° 58' north
latitude, and 29° 15' west longitude. It is 540 miles distant
from the coast of America, and 350 from the island of Fer-

nando Noronha. The highest point is only fifty feet above
the level of the sea, and the entire circumference is under
three-quarters of a mile. This small point rises abruptly out
of the depths of the ocean. Its mineralogical constitution
is not simple ; in some parts the rock is of a cherty, in others

THE VOYAGE OF THE BEAGLE 19

of a felspathic nature, including thin veins of serpentine. It
is a remarkable fact, that all the many small islands, lying
far from any continent, in the Pacific, Indian, and Atlantic
Oceans, with the exception of the Seychelles and this little
point of rock, are, I believe, composed either of coral or of
erupted matter. The volcanic nature of these oceanic islands
is evidently an extension of that law, and the effect of those
same causes, whether chemical or mechanical, from which it
results that a vast majority of the volcanoes now in action
stand either near sea-coasts or as islands in the midst of the
sea.

The rocks of St. Paul appear from a distance of a bril-
liantly white colour. This is partly owing to the dung of a
vast multitude of seafowl, and partly to a coating of a hard
glossy substance with a pearly lustre, which is intimately
united to the surface of the rocks. This, when examined
with a lens, is found to consist of numerous exceedingly
thin layers, its total thickness being about the tenth of an
inch. It contains much animal matter, and its origin, no
doubt, is due to the action of the rain or spray on the birds'
dung. Below some small masses of guano at Ascension, and
on the Abrolhos Islets, I found certain stalactitic branching
bodies, formed apparently in the same manner as the thin
white coating on these rocks. The branching bodies so closely
resembled in general appearance certain nullipora? (a family
of hard calcareous sea-plants), that in lately looking hastily
over my collection I did not perceive the difference. The
globular extremities of the branches are of a pearly texture,
like the enamel of teeth, but so hard as just to scratch plate-
glass. I may here mention, that on a part of the coast of
Ascension, where there is a vast accumulation of shelly sand,
an incrustation is deposited on the tidal rocks by the water
of the sea, resembling, as represented in the woodcut, cer-
tain cryptogamic plants (Marchantiae) often seen on damp
walls. The surface of the fronds is beautifully glossy; and
tnose parts formed where fully exposed to the light are of a
jet black colour, but those shaded under ledges are only grey.
I have shown specimens of this incrustation to several
geologists, and they all thought that they were of volcanic
or igneous origin ! In its hardness and translucency — in

20 CHARLES DARWIN

its polish, equal to that of the finest oliva-shell — in the bad
smell given out, and loss of colour under the blowpipe — it
shows a close similarity with living sea-shells. Moreover, in
sea-shells, it is known that the parts habitually covered and
shaded by the mantle of the animal, are of a paler colour
than those fully exposed to the light, just as is the case with
this incrustation. When we remember that lime, either as a
phosphate or carbonate, enters into the composition of the
hard parts, such as bones and shells, of all living animals, it
is an interesting physiological fact6 to find substances harder
than the enamel of teeth, and coloured surfaces as well
polished as those of a fresh shell, reformed through inor-
ganic means from dead organic matter — mocking, also, in
shape, some of the lower vegetable productions.

We found on St. Paul's only two kinds of birds — the
booby and the noddy. The former is a species of gannet,
and the latter a tern. Both are of a tame and stupid dis-
position, and are so unaccustomed to visitors, that I could
have killed any number of them with my geological hammer.
The booby lays her eggs on the bare rock ; but the tern makes
a very simple nest with seaweed. By the side of many of
these nests a small flying-fish was placed; which, I suppose,
had been brought by the male bird for its partner. It was
amusing to watch how quickly a large and active crab
(Graspus), which inhabits the crevices of the rock, stole the
fish from the side of the nest, as soon as we had disturbed
the parent birds. Sir W. Symonds, one of the few persons
who have landed here, informs me that he saw the crabs
dragging even the young birds out of their nests, and de-
vouring them. Not a single plant, not even a lichen, grows
on this islet ; yet it is inhabited by several insects and spiders.
The following list completes, I believe, the terrestrial fauna :
a fly (Olfersia) living on the booby, and a tick which must
have come here as a parasite on the birds; a small brown

" Mr. Horner and Sir David Brewster have described (Philosophical
Transactions, 1836, p. 65) a singular "artificial substance resembling shell."
It is deposited in fine, transparent, highly polished, brown-coloured lami-
nae, possessing peculiar optical properties, on the inside of a vessel, in
which cloth, first prepared with glue and then with lime, is made to
revolve rapidly in water. It is much softer, more transparent, and contains
more animal matter, than the natural incrustation at Ascension; but we
here again see the strong tendency which carbonate of lime and animal
matter evince to form a solid substance allied to shell.

THE VOYAGE OF THE BEAGLE 21

moth, belonging to a genus that feeds on feathers ; a beetle
(Quedius) and a woodlouse from beneath the dung; and
lastly, numerous spiders, which I suppose prey on these small
attendants and scavengers of the water-fowl. The often re-
peated description of the stately palm and other noble tropi-
cal plants, then birds, and lastly man, taking possession of
the coral islets as soon as formed, in the Pacific, is probably
not correct; I fear it destroys the poetry of this story, that
feather and dirt-feeding and parasitic insects and spiders
should be the first inhabitants of newly formed oceanic
land.

The smallest rock in the tropical seas, by giving a foun-
dation for the growth of innumerable kinds of seaweed and
compound animals, supports likewise a large number of fish.
The sharks and the seamen in the boats maintained a con-
stant struggle which should secure the greater share of the
prey caught by the fishing-lines. I have heard that a rock
near the Bermudas, lying many miles out at sea, and at a
considerable depth, was first discovered by the circumstance
of fish having been observed in the neighbourhood.

FERNANDO NORONHA, Feb. soth. — As far as I was enabled
to observe, during the few hours we stayed at this place, the
constitution of the island is volcanic, but probably not of a
recent date. The most remarkable feature is a conical hill,
about one thousand feet high, the upper part of which is
exceedingly steep, and on one side overhangs its base. The
rock is phonolite, and is divided into irregular columns. On
viewing one of these isolated masses, at first one is inclined
to believe that it has been suddenly pushed up in a semi-
fluid state. At St. Helena, however, I ascertained that some
pinnacles, of a nearly similar figure and constitution, had
been formed by the injection of melted rock into yielding
strata, which thus had formed the moulds for these gigantic
obelisks. The whole island is covered with wood; but from
the dryness of the climate there is no appearance of luxuri-
ance. Half-way up the mountain, some great masses of the
columnar rock, shaded by laurel-like trees, and ornamented
by others covered with fine pink flowers but without a single
leaf, gave a pleasing effect to the nearer parts of the scenery.

22 CHARLES DARWIN

BAHIA, OR SAN SALVADOR. BRAZIL, Feb. 2()th. — The day
has passed delightfully. Delight itself, however, is a weak
term to express the feelings of a naturalist who, for the first
time, has wandered by himself in a Brazilian forest. The
elegance of the grasses, the novelty of the parasitical plants,
the beauty of the flowers, the glossy green of the foliage,
but above all the general luxuriance of the vegetation, filled
me with admiration. A most paradoxical mixture of sound
and silence pervades the shady parts of the wood. The noise
from the insects is so loud, that it may be heard even in a
vessel anchored several hundred yards from the shore; yet
within the recesses of the forest a universal silence appears
to reign. To a person fond of natural history, such a day
as this brings with it a deeper pleasure than he can ever hope
to experience again. After wandering about for some hours,
I returned to the landing-place ; but, before reaching it, I
was overtaken by a tropical storm. I tried to find shelter
under a tree, which was so thick that it would never have
been penetrated by common English rain; but here, in a
couple of minutes, a little torrent flowed down the trunk.
It is to this violence of the rain that we must attribute the
verdure at the bottom of the thickest woods: if the showers
were like those of a colder climate, the greater part would
be absorbed or evaporated before it reached the ground. I
will not at present attempt to describe the gaudy scenery
of this noble bay, because, in our homeward voyage, we
called here a second time, and I shall then have occasion to
remark on it.

Along the whole coast of Brazil, for a length of at least
2000 miles, and certainly for a considerable space inland,
wherever solid rock occurs, it belongs to a granitic forma-
tion. The circumstance of this enormous area being con-
stituted of materials which most geologists believe to have
been crystallized when heated under pressure, gives rise to
many curious reflections. Was this effect produced beneath
the depths of a profound ocean ? or did a covering of strata
formerly extend over it, which has since been removed?
Can we believe that any power, acting for a time short of
infinity, could have denuded the granite over so many thou-
sand square leagues?

THE VOYAGE OF THE BEAGLE 23

On a point not far from the city, where a rivulet en-
tered the sea, I observed a fact connected with a subject dis-
cussed by Humboldt.7 At the cataracts of the great rivers
Orinoco, Nile, and Congo, the syenitic rocks are coated by
a black substance, appearing as if they had been polished
with plumbago. The layer is of extreme thinness; and on
analysis by Berzelius it was found to consist of the oxides
of manganese and iron. In the Orinoco it occurs on the
rocks periodically washed by the floods, and in those parts
alone where the stream is rapid ; or, as the Indians say, " the
rocks are black where the waters are white." Here the coat-
ing is of a rich brown instead of a black colour, and seems
to be composed of ferruginous matter alone. Hand speci-
mens fail to give a just idea of these brown burnished stones
which glitter in the sun's rays. They occur only within the
limits of the tidal waves; and as the rivulet slowly trickles
down, the surf must supply the polishing power of the cat-
aracts in the great rivers. In like manner, the rise and fall
of the tide probably answer to the periodical inundations;
and thus the same effects are produced under apparently dif-
ferent but really similar circumstances. The origin, how-
ever, of these coatings of metallic oxides, which seem as if
cemented to the rocks, is not understood; and no reason, I
believe, can be assigned for their thickness remaining the
same.

One day I was amused by watching the habits of the
Diodon antennatus, which was caught swimming near the
shore. This fish, with its flabby skin, is well known to pos-
sess the singular power of distending itself into a nearly
spherical form. After having been taken out of water for
a short time, and then again immersed in it, a considerable
quantity both of water and air is absorbed by the mouth,
and perhaps likewise by the branchial orifices. This process
is effected by two methods: the air is swallowed, and is then
forced into the cavity of the body, its return being prevented
by a muscular contraction which is externally visible: but
the water enters in a gentle stream through the mouth,
which is kept wide open and motionless; this latter action
must, therefore, depend on suction. The skin about the

T Pers. Narr., vol. v.. pt. I., p. 18.

abdomen is much looser than that on the back; hence, dur-
ing the inflation, the lower surface becomes far more dis-
tended than the upper; and the fish, in consequence, floats
with its back downwards. Cuvier doubts whether the Dio-
don in this position is able to swim ; but not only can it thus
move forward in a straight line, but it can turn round to
either side. This latter movement is effected solely by the
aid of the pectoral fins; the tail being collapsed, and not
used. From the body being buoyed up with so much air, the
branchial openings are out of water, but a stream drawn in
by the mouth constantly flows through them.

The fish, having remained in this distended state for a
short time, generally expelled the air and water with con-
siderable force from the branchial apertures and mouth. It
could emit, at will, a certain portion of the water; and it
appears, therefore, probable that this fluid is taken in partly
for the sake of regulating its specific gravity. This Diodon
possessed several means of defence. It could give a severe
bite, and could eject water from its mouth to some distance,
at the same time making a curious noise by the movement
of its jaws. By the inflation of its body, the papillae, with
which the skin is covered, become erect and pointed. But
the most curious circumstance is, that it secretes from the
skin of its belly, when handled, a most beautiful carmine-
red fibrous matter, which stains ivory and paper in so per-
manent a manner that the tint is retained with all its bright-
ness to the present day: I am quite ignorant of the nature
and use of this secretion. I have heard from Dr. Allan of
Forres, that he has frequently found a Diodon, floating alive
and distended, in the stomach of the shark; and that on
several occasions he has known it eat its way, not only
through the coats of the stomach, but through the sides of
the monster, which has thus been killed. Who would ever
have imagined that a little soft fish could have destroyed
the great and savage shark?

March i8th. — We sailed from Bahia. A few days after-
wards, when not far distant from the Abrolhos Islets, my
attention was called to a reddish-brown appearance in the
sea. The whole surface of the water, as it appeared under a

THE VOYAGE OF THE BEAGLE 25

weak lens, seemed as if covered by chopped bits of hay, with
their ends jagged. These are minute cylindrical confervae,
in bundles or rafts of from twenty to sixty in each. Mr.
Berkeley informs me that they are the same species (Tricho-
desmium erythraeum) with that found over large spaces in
the Red Sea, and whence its name of Red Sea is derived.8
Their numbers must be infinite : the ship passed through
several bands of them, one of which was about ten yards
wide, and, judging from the mud-like colour of the water,
at least two and a half miles long. In almost every long
voyage some account is given of these confervae. They ap-
pear especially common in the sea near Australia; and off
Cape Leeuwin I found an allied but smaller and apparently
different species. Captain Cook, in his third voyage, re-
marks, that the sailors gave to this appearance the name of
sea-sawdust.

Near Keeling Atoll, in the Indian Ocean, I observed
many little masses of confervae a few inches square, consist-
ing of long cylindrical threads of excessive thinness, so as
to be barely visible to the naked eye, mingled with other
rather larger bodies, finely conical at both ends. Two of
these are shown in the woodcut united together. They vary
in length from .04 to .06, and even to .08 of an inch in
length ; and in diameter from .006 to .008 of an inch. Near
one extremity of the cylindrical part, a green septum, formed
of granular matter, and thickest in the middle, may generally
be seen. This, I believe, is the bottom of a most delicate,
colourless sac, composed of a pulpy substance, which lines
the exterior case, but does not extend within the extreme
conical points. In some specimens,
small but perfect spheres of brown-
ish granular matter supplied the
places of the septa; and I observed the curious process by
which they were produced. The pulpy matter of the internal
coating suddenly grouped itself into lines, some of which
assumed a form radiating from a common centre; it then
continued, with an irregular and rapid movement, to con-
tract itself, so that in the course of a second the whole was

Scienc. Nat., Dec. 1844.

26 CHARLES DARWIN

united into a perfect little sphere, which occupied the posi-
tion of the septum at one end of the now quite hollow case.
The formation of the granular sphere was hastened by any
accidental injury. I may add, that frequently a pair of these
bodies were attached to each other, as represented above,
cone beside cone, at that end where the septum occurs.

I will add here a few other observations connected with
the discoloration of the sea from organic causes. On the
coast of Chile, a few leagues north of Concepcion, the Beaglt
one day passed through great bands of muddy water, exactly
like that of a swollen river; and again, a degree south of
Valparaiso, when fifty miles from the land, the same appear-
ance was still more extensive. Some of the water placed
in a glass was of a pale reddish tint; and, examined under
a microscope, was seen to swarm with minute animalcula
darting about, and often exploding. Their shape is oval,
and contracted in the middle by a ring of vibrating curved
ciliae. It was, however, very difficult to examine them with
care, for almost the instant motion ceased, even while cross-
ing the field of vision, their bodies burst. Sometimes both
ends burst at once, sometimes only one, and a quantity of
coarse, brownish, granular matter was ejected. The animal
an instant before bursting expanded to half again its natu-
ral size; and the explosion took place about fifteen seconds
after the rapid progressive motion had ceased: in a few
cases it was preceded for a short interval by a rotatory
movement on the longer axis. About two minutes after any
number were isolated in a drop of water, they thus perished.
The animals move with the narrow apex forwards, by the
aid of their vibratory ciliae, and generally by rapid starts.
They are exceedingly minute, and quite invisible to the
naked eye, only covering a space equal to the square of the
thousandth of an inch. Their numbers were infinite; for
the smallest drop of water which I could remove contained
very many. In one day we passed through two spaces of
water thus stained, one of which alone must have extended
over several square miles. What incalculable numbers of
these microscopical animals ! The colour of the water, as
seen at some distance, was like that of a river which has
flowed through a red clay district; but under the shade of

THE VOYAGE OF THE BEAGLE 27

the vessel's side it was quite as dark as chocolate. The line
where the red and blue water joined was distinctly defined.
The weather for some days previously had been calm, and the
ocean abounded, to an unusual degree, with living creatures."
In the sea around Tierra del Fuego, and at no great dis-
tance from the land, I have seen narrow lines of water of a
bright red colour, from the number of Crustacea, which
somewhat resemble in form large prawns. The sealers call
them whale-food. Whether whales feed on them I do not
know; but terns, cormorants, and immense herds of great
unwieldy seals derive, on some parts of the coast, their
chief sustenance from these swimming crabs. Seamen
invariably attribute the discoloration of the water to spawn ;
but I found this to be the case only on one occasion. At
the distance of several leagues from the Archipelago of the
Galapagos, the ship sailed through three strips of a dark
yellowish, or mudlike water; these strips were some miles
long, but only a few yards wide, and they were separated
from the surrounding water by a sinuous yet distinct mar-
gin. The colour was caused by little gelatinous balls, about
th-e fifth of an inch in diameter, in which numerous minute
spherical ovules were imbedded: they were of two distinct
kinds, one being of a reddish colour and of a different shape
from the other. I cannot form a conjecture as to what two
kinds of animals these belonged. Captain Colnett remarks,
that this appearance is very common among the Galapagos
Islands, and that the directions of the bands indicate that
of the currents; in the described case, however, the line was
caused by the wind. The only other appearance which I
have to notice, is a thin oily coat on the water which dis-
plays iridescent colours. I saw a considerable tract of the
ocean thus covered on the coast of Brazil; the seamen
attributed it to the putrefying carcase of some whale, which
probably was floating at no great distance. I do not here
mention the minute gelatinous particles, hereafter to be

9 M. Lesson (Voyage de la Coquille, torn, i., p. 255) mentions red water
off Lima, apparently produced by the same cause. Peron, the distinguished
naturalist, in the Voyage aux Terres Australes, gives no less than twelve
references _ to voyagers who have alluded to the discoloured waters of the

28 CHARLES DARWIN

referred to, which are frequently dispersed throughout the
water, for they are not sufficiently abundant to create any
change of colour.

There are two circumstances in the above accounts which
appear remarkable : first, how do the various bodies which
form the bands with defined edges keep together? In the
case of the prawn-like crabs, their movements were as
coinstantaneous as in a regiment of soldiers ; but this cannot
happen from anything like voluntary action with the ovules,
or the confervae, nor is it probable among the infusoria.
Secondly, what causes the length and narrowness of the
bands? The appearance so much resembles that which may
be seen in every torrent, where the stream uncoils into long
streaks the froth collected in the eddies, that I must attrib-
ute the effect to a similar action either of the currents of the
air or sea. Under this supposition we must believe that the
various organized bodies are produced in certain favourable
places, and are thence removed by the set of either wind
or water. I confess, however, there is a very great difficulty
in imagining any one spot to be the birthplace of the millions
of millions of animalcula and confervae: for whence come
the germs at such points? — the parent bodies having been
distributed by the winds and waves over the immense ocean.
But on no other hypothesis can I understand their linear
grouping. I may add that Scoresby remarks that green
water abounding with pelagic animals is invariably found
in a certain part of the Arctic Sea.

APRIL 4th to July 5th, 1832. — A few days after our

/-\ arrival I became acquainted with an Englishman who

was going to visit his estate, situated rather more

than a hundred miles from the capital, to the northward of

Cape Frio. I gladly accepted his kind offer of allowing me

to accompany him.

April 8th. — Our party amounted to seven. The first stage
was very interesting. The day was powerfully hot, and as
we passed through the woods, everything was motionless,
excepting the large and brilliant butterflies, which lazily
fluttered about. The view seen when crossing the hills
behind Praia Grande was most beautiful ; the colours were
intense, and the prevailing tint a dark blue; the sky and the
calm waters of the bay vied with each other in splendour.
After passing through some cultivated country, we entered
a forest, which in the grandeur of all its parts could not be
exceeded. We arrived by midday at Ithacaia; this small
village is situated on a plain, and round the central house
are the huts of the negroes. These, from their regular form
and position, reminded me of the drawings of the Hottentot
habitations in Southern Africa. As the moon rose early, we
determined to start the same evening for our sleeping-place
at the Lagoa Marica. As it was growing dark we passed
under one of the massive, bare, and steep hills of granite
which are so common in this country. This spot is notorious
from having been, for a long time, the residence of some

30 CHARLES DARWIN

runaway slaves, who, by cultivating a little ground near the
top, contrived to eke out a subsistence. At length they were
discovered, and a party of soldiers being sent, the whole
were seized with the exception of one old woman, who,
sooner than again be led into slavery, dashed herself to
pieces from the summit of the mountain. In a Roman
matron this would have been called the noble love of free-
dom : in a poor negress it is mere brutal obstinacy. We
continued riding for some hours. For the few last miles the
road was intricate, and it passed through a desert waste of
marshes and lagoons. The scene by the dimmed light of the
moon was most desolate. A few fireflies flitted by us; and
the solitary snipe, as it rose, uttered its plaintive cry. The
distant and sullen roar of the sea scarcely broke the stillness
of the night.

April pth. — We left our miserable sleeping-place before
sunrise. The road passed through a narrow sandy plain,
lying between the sea and the interior salt lagoons. The
number of beautiful fishing birds, such as egrets and cranes,
and the succulent plants assuming most fantastical forms,
gave to the scene an interest which it would not otherwise
have possessed. The few stunted trees were loaded with
parasitical plants, among which the beauty and delicious
fragrance of some of the orchideae were most to be admired.
As the sun rose, the day became extremely hot, and the
reflection of the light and heat from the white sand was very
distressing. We dined at Mandetiba; the thermometer in
the shade being 84°. The beautiful view of the distant
wooded hills, reflected in the perfectly calm water of an
extensive lagoon, quite refreshed us. As the venda1 here
was a very good one, and I have the pleasant, but rare
remembrance, of an excellent dinner, I will be grateful and
presently describe it, as the type of its class. These houses
are often large, and are built of thick upright posts, with
boughs interwoven, and afterwards plastered. They seldom
have floors, and never glazed windows; but are generally
pretty well roofed. Universally the front part is open, form-
ing a kind of verandah, in which tables and benches are
placed. The bed-rooms join on each side, and here the

senger may sleep as comfortably as he can, on a wooden
platform, covered by a thin straw mat. The venda stands
in a courtyard, where the horses are fed. On first arriving
it was our custom to unsaddle the horses and give them
their Indian corn; then, with a low bow, to ask the senhor
to do us the favour to give us something to eat. " Anything
you choose, sir," was his usual answer. For the few first
times, vainly I thanked providence for having guided us
to so good a man. The conversation proceeding, the case
universally became deplorable. " Any fish can you do us the
favour of giving?" — "Oh! no, sir." — "Any soup?" — "No,
sir." — " Any bread ? " — " Oh ! no, sir." — " Any dried meat ? "
— " Oh ! no, sir." If we were lucky, by waiting a couple of
hours, we obtained fowls, rice, and farinha. It not unfre-
quently happened, that we were obliged to kill, with stones,
the poultry for our own supper. When, thoroughly exhausted
by fatigue and hunger, we timorously hinted that we should
be glad of our meal, the pompous, and (though true) most
unsatisfactory answer was, " It will be ready when it is
ready." If we had dared to remonstrate any further, we
should have been told to proceed on our journey, as being
too impertinent. The hosts are most ungracious and dis-
agreeable in their manners; their houses and their persons
are often filthily dirty; the want of the accommodation of
forks, knives, and spoons is common; and I am sure no cot-
tage or hovel in England could be found in a state so utterly
destitute of every comfort. At Campos Novos, however, we
fared sumptuously ; having rice and fowls, biscuit, wine, and
spirits, for dinner; coffee in the evening, and fish with coffee
for breakfast. All this, with good food for the horses, only
cost 2s. 6d. per head. Yet the host of this venda, being
asked if he knew anything of a whip which one of the party
had lost, gruffly answered, " How should I know ? why did
you not take care of it? — I suppose the dogs have eaten it."
Leaving Mandetiba, we continued to pass through an in-
tricate wilderness of lakes; in some of which were fresh,
in others salt water shells. Of the former kinds, I found
a Limnsea in great numbers in a lake, into which, the in-
habitants assured me that the sea enters once a year, and
sometimes oftener, and makes the water quite salt. I have

no doubt many interesting facts, in relation to marine and
fresh water animals, might be observed in this chain of
lagoons, which skirt the coast of Brazil. M. Gay2 has
stated that he found in the neighbourhood of Rio, shells of
the marine genera solen and mytilus, and fresh water am-
pullarise, living together in brackish water. I also frequently
observed in the lagoon near the Botanic Garden, where the
water is only a little less salt than in the sea, a species of
hydrophilus, very similar to a water-beetle common in the
ditches of England : in the same lake the only shell belonged
to a genus generally found in estuaries.

Leaving the coast for a time, we again entered the forest.
The trees were very lofty, and remarkable, compared with
those of Europe, from the whiteness of their trunks. I see
by my note-book, " wonderful and beautiful, flowering para-
sites," invariably struck me as the most novel object in these
grand scenes. Travelling onwards we passed through tracts
of pasturage, much injured by the enormous conical ants'
nests, which were nearly twelve feet high. They gave to the
plain exactly the appearance of the mud volcanos at Jorullo,
as figured by Humboldt. We arrived at Engenhodo after it
was dark, having been ten hours on horseback. I never
ceased, during the whole journey, to be surprised at the
amount of labour which the horses were capable of endur-
ing; they appeared also to recover from any injury much
sooner than those of our English breed. The Vampire bat
is often the cause of much trouble, by biting the horses on
their withers. The injury is generally not so much owing
to the loss of blood, as to the inflammation which the pres-
sure of the saddle afterwards produces. The whole circum-
stance has lately been doubted in England; I was therefore
fortunate in being present when one (Desmodus d'orbignyi,
Wat.) was actually caught on a horse's back. We were
bivouacking late one evening near Coquimbo, in Chile, when
my servant, noticing that one of the horses was very restive,
went to see what was the matter, and fancying he could
distinguish something, suddenly put his hand on the beast's
withers, and secured the vampire. In the morning the spot
where the bite had been inflicted was easily distinguished

from being slightly swollen and bloody. The third day
afterwards we rode the horse, without any ill effects.

April ijth. — After three days' travelling we arrived at
Socego, the estate of Senhor Manuel Figuireda, a relation
of one of our party. The house was simple, and, though like
a barn in form, was well suited to the climate. In the sitting-
room gilded chairs and sofas were oddly contrasted with the
whitewashed walls, thatched roof, and windows without
glass. The house, together with the granaries, the stables,
and workshops for the blacks, who had been taught vari-
ous trades, formed a rude kind of quadrangle ; in the centre
of which a large pile of coffee was drying. These buildings
stand on a little hill, overlooking the cultivated ground, and
surrounded on every side by a wall of dark green luxuriant
forest. The chief produce of this part of the country is
coffee. Each tree is supposed to yield annually, on an aver-
age, two pounds ; but some give as much as eight. Mandioca
or cassada is likewise cultivated in great quantity. Every
part of this plant is useful; the leaves and stalks are eaten
by the horses, and the roots are ground into a pulp, which,
when pressed dry and baked, forms the farinha, the prin-
cipal article of sustenance in the Brazils. It is a curious,
though well-known fact, that the juice of this most nutritious
plant is highly poisonous. A few years ago a cow died at
this Fazenda, in consequence of having drunk some of it.
Senhor Figuireda told me that he had planted, the year be-
fore, one bag of feijao or beans, and three of rice ; the
former of which produced eighty, and the latter three hun-
dred and twenty fold. The pasturage supports a fine stock
of cattle, and the woods are so full of game that a deer had
been killed on each of the three previous days. This profu-
sion of food showed itself at dinner, where, if the tables did
not groan, the guests surely did ; for each person is expected
to eat of every dish. One day, having, as I thought, nicely
calculated so that nothing should go away untasted, to my
utter dismay a roast turkey and a pig appeared in all their
substantial reality. During the meals, it was the employ-
ment of a man to drive out of the room sundry old hounds,
and dozens of little black children, which crawled in together,
at every opportunity. As long as the idea of slavery could be
VOL. xxix — B HC

34 CHARLES DARWIN

banished, there was something exceedingly fascinating in
this simple and patriarchal style of living: it was such a
perfect retirement and independence from the rest of the
world.

As soon as any stranger is seen arriving, a large bell is set
tolling, and generally some small cannon are fired. The
event is thus announced to the rocks and woods, but to noth-
ing else. One morning I walked out an hour before daylight
to admire the solemn stillness of the scene ; at last, the silence
was broken by the morning hymn, raised on high by the
whole body of the blacks; and in this manner their daily
work is generally begun. On such fazendas as these, I have
no doubt the slaves pass happy and contented lives. On
Saturday and Sunday they work for themselves, and in this
fertile climate the labour of two days is sufficient to support
a man and his family for the whole week.

April iqth. — Leaving Socego, we rode to another estate on
the Rio Macae, which was the last patch of cultivated ground
in that direction. The estate was two and a half miles long,
and the owner had forgotten how many broad. Only a very
small piece had been cleared, yet almost every acre was
capable of yielding all the various rich productions of a trop-
ical land. Considering the enormous area of Brazil, the pro-
portion of cultivated ground can scarcely be considered as
anything, compared to that which is left in the state of
nature: at some future age, how vast a population it will
support ! During the second day's journey we found the
road so shut up, that it was necessary that a man should go
ahead with a sword to cut away the creepers. The forest
abounded with beautiful objects; among which the tree ferns,
though not large, were, from their bright green foliage, and
the elegant curvature of their fronds, most worthy of admira-
tion. In the evening it rained very heavily, and although the
thermometer stood at 65°, I felt very cold. As soon as the
rain ceased, it was curious to observe the extraordinary evap-
oration which commenced over the whole extent of the
forest. At the height of a hundred feet the hills were buried
in a dense white vapour, which rose like columns of smoke
from the most thickly wooded parts, and especially from the
valleys. I observed this phenomenon on several occasions.

THE VOYAGE OF THE BEAGLE 35

I suppose it is owing to the large surface of foliage, previ-
ously heated by the sun's rays.

While staying at this estate, I was very nearly being an
eye-witness to one of those atrocious acts which can only
take place in a slave country. Owing to a quarrel and a
lawsuit, the owner was on the point of taking all the women
and chjjdren from the male slaves, and selling them sepa-
rately at the public auction at Rio. Interest, and not any
feeling of compassion, prevented this act. Indeed, I do not
believe the inhumanity of separating thirty families, who
had lived together for many years, even occurred to the
owner. Yet I will pledge myself, that in humanity and
good feeling he was superior to the common run of men.
It may be said there exists no limit to the blindness of inter-
est and selfish habit. I may mention one very trifling anec-
dote, which at the time struck me more forcibly than any
story of cruelty. I was cross'ng a ferry with a negro, who
was uncommonly stupid. In endeavouring to make him
understand, I talked loud, and made signs, in doing which I
passed my hand near his face. He, I suppose, thought I was
in a passion, and was going to strike him; for instantly,
with a frightened look and half-shut eyes, he dropped his
hands. I shall never forget my feelings of surprise, disgust,
and shame, at seeing a great powerful man afraid even to
ward off a blow, directed, as he thought, at his face. This
man had been trained to a degradation lower than the
slavery of the most helpless animal.

April i8th. — In returning we spent two days at Socego,
and I employed them in collecting insects in the forest. The
greater number of trees, although so lofty, are not more
than three or four feet in circumference. There are, of
course, a few of much greater dimensions. Senhor Manuel
was then making a canoe 70 feet in length from a solid trunk,
which had originally been no feet long, and of great thick-
ness. The contrast of palm trees, growing amidst the com-
mon branching kinds, never fails to give the scene an inter-
tropical character. Here the woods were ornamented by the
Cabbage Palm — one of the most beautiful of its family. With
a stem so narrow that it might be clasped with the two
hands, it waves its elegant head at the height of forty or

36 CHARLES DARWIN

fifty feet above the ground. The woody creepers, themselves
covered by other creepers, were of great thickness : some
which I measured were two feet in circumference. Many of
the older trees presented a very curious appearance from
the tresses of a liana hanging from their boughs, and resem-
bling bundles of hay. If the eye was turned from the world
of foliage above, to the ground beneath, it was attracted by
the extreme elegance of the leaves of the ferns and mimosae.
The latter, in some parts, covered the surface with a brush-
wood only a few inches high. In walking across these thick
beds of mimosae, a broad track was marked by the change
of shade, produced by the drooping of their sensitive petioles.
It is easy to specify the individual objects of admiration in
these grand scenes ; but it is not possible to give an adequate
idea of the higher feelings of wonder, astonishment, and
devotion, which fill and elevate the mind.

April ipth. — Leaving Socego, during the two first days,
we retraced our steps. It was very wearisome work, as the
road generally ran across a glaring hot sandy plain, not
far from the coast. I noticed that each time the horse put
its foot on the fine siliceous sand, a gentle chirping noise
was produced. On the third day we took a different line,
and passed through the gay little village of Madre de Deos.
This is one of the principal lines of road in Brazil; yet it
was in so bad a state that no wheeled vehicle, excepting the
clumsy bullock- wagon, could pass along. In our whole jour-
ney we did not cross a single bridge built of stone; and
those made of logs of wood were frequently so much out of
repair, that it was necessary to go on one side to avoid them.
All distances are inaccurately known. The road is often
marked by crosses, in the place of milestones, to signify
where human blood has been spilled. On the evening of the
23rd we arrived at Rio, having finished our pleasant little
excursion.

During the remainder of my stay at Rio, I resided in a
cottage at Botofogo Bay. It was impossible to wish for
anything more delightful than thus to spend some weeks
in so magnificent a country. In England any person fond
of natural history enjoys in his walks a great advantage, by

THE VOYAGE OF THE BEAGLE 37

always having something to attract his attention ; but in
these fertile climates, teeming with life, the attractions are
so numerous, that he is scarcely able to walk at all.

The few observations which I was enabled to make were
almost exclusively confined to the invertebrate animals. The
existence*of a division of the genus Planaria, which inhabits
the dry land, interested me much. These animals are of so
simple a structure, that Cuvier has arranged them with the
intestinal worms, though never found within the bodies of
other animals. Numerous species inhabit both salt and fresh
water; but those to which I allude were found, even in the
drier parts of the forest, beneath logs of rotten wood, on
which I believe they feed. In general form they resemble
little slugs, but are very much narrower in proportion, and
several of the species are beautifully coloured with longi-
tudinal stripes. Their structure is very simple: near the
middle of the under or crawling surface there are two small
transverse slits, from the anterior one of which a funnel-
shaped and highly irritable mouth can be protruded. For
some time after the rest of the animal was completely dead
from the effects of salt water or any other cause, this organ
still retained its vitality.

I found no less than twelve different species of terrestrial
Planariae in different parts of the southern hemisphere.8
Some specimens which I obtained at Van Dieman's Land,
I kept alive for nearly two months, feeding them on rotten
wood. Having cut one of them transversely into two nearly
equal parts, in the course of a fortnight both had the shape
of perfect animals. I had, however, so divided the body,
that one of the halves contained both the inferior orifices,
and the other, in consequence, none. In the course of twenty-
five days from the operation, the more perfect half could
not have been distinguished from any other specimen. The
other had increased much in size ; and towards its posterior
end, a clear space was formed in the parenchymatous mass,
in which a rudimentary cup-shaped mouth could clearly be
distinguished ; on the under surface, however, no correspond-
ing slit was yet open. If the increased heat of the weather,

3 I have described and named these species in the Annals of Nat. Hist.,
vol. xiv. p. 241.

38 CHARLES DARWIN

as we approached the equator, had not destroyed all the
individuals, there can be no doubt that this last step would
have completed its structure. Although so well-known an
experiment, it was interesting to watch the gradual produc-
tion of every essential organ, out of the simple extremity
of another animal. It is extremely difficult to preserve these
Planariae; as soon as the cessation of life allows the ordi-
nary laws of change to act, their entire bodies become soft
and fluid, with a rapidity which I have never seen equalled.

I first visited the forest in which these Planariae were
found, in company with an old Portuguese priest who took
me out to hunt with him. The sport consisted in turning
into the cover a few dogs, and then patiently waiting to fire
at any animal which might appear. We were accompanied
by the son of a neighbouring farmer — a good specimen of
a wild Brazilian youth. He was dressed in a tattered old
shirt and trousers, and had his head uncovered: he carried
an old-fashioned gun and a large knife. The habit of carry-
ing the knife is universal ; and in traversing a thick wood
it is almost necessary, on account of the creeping plants.
The frequent occurrence of murder may be partly attributed
to this habit. The Brazilians are so dexterous with the
knife, that they can throw it to some distance with precision,
and with sufficient force to cause a fatal wound. I have seen
a number of little boys practising this art as a game of play,
and from their skill in hitting an upright stick, they promised
well for more earnest attempts. My companion, the day
before, had shot two large bearded monkeys. These animals
have prehensile tails, the extremity of which, even after
death, can support the whole weight of the body. One of
them thus remained fast to a branch, and it was necessary
to cut down a large tree to procure it. This was soon effected,
and down came tree and monkey with an awful crash. Our
day's sport, besides the monkey, was confined to sundry small
green parrots and a few toucans. I profited, however, by my
acquaintance with the Portuguese padre, for on another
occasion he gave me a fine specimen of the Yagouaroundi
cat.

Every one has heard of the beauty of the scenery near
Botofogo. The house in which I lived was seated close

THE VOYAGE OF THE BEAGLE 99

beneath the well-known mountain of the Corcovado. It has
been remarked, with much truth, that abruptly conical hills
are characteristic of the formation which Humboldt desig-
nates as gneiss-granite. Nothing can be more striking than
the effect of these huge rounded masses of naked rock rising
out of the most luxuriant vegetation.

I was often interested by watching the clouds, which,
rolling in from seaward, formed a bank just beneath the
highest point of the Corcovado. This mountain, like most
others, when thus partly veiled, appeared to rise to a far
prouder elevation than its real height of 2300 feet. Mr.
Daniell has observed, in his meteorological essays, that a
cloud sometimes appears fixed on a mountain summit, while
the wind continues to blow over it. The same phenomenon
here presented a slightly different appearance. In this case
the cloud was clearly seen to curl over, and rapidly pass
by the summit, and yet was neither diminished nor increased
in size. The sun was setting, and a gentle southerly breeze,
striking against the southern side of the rock, mingled its
current with the colder air above; and the vapour was thus
condensed; but as the light wreaths of cloud passed over
the ridge, and came within the influence of the warmer atmos-
phere of the northern sloping bank, they were immediately
re-dissolved.

The climate, during the months of May and June, or the
beginning of winter, was delightful. The mean tempera-
ture, from observations taken at nine o'clock, both morning
and evening, was only 72°. It often rained heavily, but
the drying southerly winds soon again rendered the walks
pleasant. One morning, in the course of six hours, 1.6 inches
of rain fell. As this storm passed over the forests which
surround the Corcovado, the sound produced by the drops
pattering on the countless multitude of leaves was very re-
markable, it could be heard at the distance of a quarter of a
mile, and was like the rushing of a great body of water.
After the hotter days, it was delicious to sit quietly in the
garden and watch the evening pass into night. Nature, in
these climes, chooses her vocalists from more humble per-
formers than in Europe. A small frog, of the genus Hyla,
sits on a blade of grass about an inch above the surface of

40 CHARLES DARWIN

the water, and sends forth a pleasing chirp: when several
are together they sing in harmony on different notes. I had
some difficulty in catching a specimen of this frog. The
genus Hyla has its toes terminated by small suckers; and I
found this animal could crawl up a pane of glass, when
placed absolutely perpendicular. Various cicidae and crickets,
at the same time, keep up a ceaseless shrill cry, but which,
softened by the distance, is not unpleasant. Every evening
after dark this great concert commenced; and often have I
sat listening to it, until my attention has been drawn away
by some curious passing insect.

At these times the fireflies are seen flitting about from
hedge to hedge. On a dark night the light can be seen at
about two hundred paces distant. It is remarkable that in
all the different kinds of glowworms, shining elaters, and
various marine animals (such as the Crustacea, medusae,
nereidae, a coralline of the genus Clytia, and Pyrosma),
which I have observed, the light has been of a well-marked
green colour. All the fireflies, which I caught here, belonged
to the Lampyridae (in which family the English glowworm
is included), and the greater number of specimens were of
Lampyris occidentalis.* I found that this insect emitted
the most brilliant flashes when irritated: in the intervals,
the abdominal rings were obscured. The flash was almost
co-instantaneous in the two rings, but it was just perceptible
first in the anterior one. The shining matter was fluid and
very adhesive : little spots, where the skin had been torn, con-
tinued bright with a slight scintillation, whilst the uninjured
parts were obscured. When the insect was decapitated the
rings remained uninterruptedly bright, but not so brilliant
as before: local irritation with a needle always increased
the vividness of the light. The rings in one instance retained
their luminous property nearly twenty-four hours after the
death of the insect. From these facts it would appear proba-
ble, that the animal has only the power of concealing or
extinguishing the light for short intervals, and that at other
times the display is involuntary. On the muddy and wet
gravel-walks I found the larvae of this lampyris in great num-

4 I am greatly indebted to Mr. Waterhouse for his kindness in naming
for me this and many other insects, and in giving me much valuable
assistance.

THE VOYAGE OF THE BEAGLE 41

bers: they resembled in general form the female of the
English glowworm. These larvae possessed but feeble lumi-
nous powers; very differently from their parents, on the
slightest touch they feigned death and ceased to shine; nor
did irritation excite any fresh display. I kept several of
them alive for some time : their tails are very singular organs,
for they act, by a well-fitted contrivance, as suckers or organs
of attachment, and likewise as reservoirs for saliva, or some
such fluid. I repeatedly fed them on raw meat; and I in-
variably observed, that every now and then the extremity
of the tail was applied to the mouth, and a drop of fluid
exuded on the meat, which was then in the act of being con-
sumed. The tail, notwithstanding so much practice, does not
seem to be able to find its way to the mouth ; at least the neck
was always touched first, and apparently as a guide.

When we were at Bahia, an elater or beetle (Pyrophorus
luminosus, Illig.) seemed the most common luminous insect.
The light in this case was also rendered more brilliant by
irritation. I amused myself one day by observing the spring-
ing powers of this insect, which have not, as it appears to
me, been properly described.5 The elater, when placed on
its back and preparing to spring, moved its head and thorax
backwards, so that the pectoral spine was drawn out, and
rested on the edge of its sheath. The same backward move-
ment being continued, the spine, by the full action of the
muscles, was bent like a spring; and the insect at this mo-
ment rested on the extremity of its head and wing-cases.
The effort being suddenly relaxed, the head and thorax flew
up, and in consequence, the base of the wing-cases struck
the supporting surface with such force, that the insect by
the reaction was jerked upwards to the height of one or
two inches. The projecting points of the thorax, and the
sheath of the spine, served to steady the whole body during
the spring. In the descriptions which I have read, sufficient
stress does not appear to have been laid on the elasticity of
the spine : so sudden a spring could not be the result of sim-
ple muscular contraction, without the aid of some mechanical
contrivance.

On several occasions I enjoyed some short but most pleas-

cm «n raimu I started early and walked to the

Gacwia, or tDpiail mountain. The air was delightfully cool
and fajyJMt; and the drops of dew still glittered on the
leaves of Ae large EEaceom pikmts, which shaded the stream-

lets of dear water. Sitfrtitg down on a block of granite, it
mas delightful to wateh Ae various insects and birds as they

such shady retired spate. Whenever I saw these little crea-

THE VOYAGE OF THE BEAGLE 43

tore* tarring rotmd a flower, with their wings vibrating so
rapidly as to be scarcely risible, I was reminded of die
sphinx moths: their movements and habits are indeed in
many respects very similar.

Following a pathway, I entered a noble forest, and from
a height of five or six hundred feet, one of those splendid
views was presented, which are so common on every side
of Rio. At this elevation the landscape attains its most
brilliant tint; and every form, every shade, so completely
surpasses in magnificence all that the European has ever
beheld in his own country, that be knows not how to ex-
press his feelings. The general effect frequently recalled
to my mind the gayest scenery of the Opera-house or the
great theatres. I never returned from these excursions
empty-handed. This day I found a specimen of a curious
fungus, called HymenophaUns. Most people know the Eng-
lish Phallus, which in autumn taints the air with its odious
smell: this, however, as the entomologist is aware, is, to
some of our beetles a delightful fragrance. So was it here;
for a Strongyras, attracted by the odour, alighted on the fun-
gus as I carried it in my hand. We here see in two distant
countries a similar relation between plants and insects of the
same families, though the species of both are different. When
man is the agent in introducing into a country a new species,
this relation is often broken: as one instance of this I may
mention, that the leaves of the cabbages and lettuces, which in
England afford food to such a multitude of slugs and cater-
pillars, in the gardens near Rio are untouched.

During our stay at Brazil I made a large collection of
insects. A few general observations on the comparative im-
portance of the different orders may be interesting to die
English entomologist. The large and brilliantly coloured
Lepidoptera bespeak the zone diey inhabit, far more plainly
than any other race of ar»r«**ai* I allude only to the butter-
flies; for the moths, contrary to what might have been
expected from die rankness of the vegetation, certainly ap-
peared in much fewer numbers dian in our own temperate
regions. I was much surprised at die habits of Papilio f ero-
nia. This butterfly is not uncommon, and generally frequents
die orange-groves. Although a high flier, yet it very fre-

44 CHARLES DARWIN

quently alights on the trunks of trees. On these occasions
its head is invariably placed downwards ; and its wings are
expanded in a horizontal plane, instead of being folded verti-
cally, as is commonly the case. This is the only butterfly
which I have ever seen, that uses its legs for running. Not
being aware of this fact, the insect, more than once, as I
cautiously approached with my forceps, shuffled on one side
just as the instrument was on the point of closing, and thus
escaped. But a far more singular fact is the power which
this species possesses of making a noise.8 Several times when
a pair, probably male and female, were chasing each other
in an irregular course, they passed within a few yards of me ;
and I distinctly heard a clicking noise, similar to that pro-
duced by a toothed wheel passing under a spring catch. The
noise was continued at short intervals, and could be dis-
tinguished at about twenty yards' distance: I am certain
there is no error in the observation.

I was disappointed in the general aspect of the Coleop-
tera. The number of minute and obscurely coloured beetles
is exceedingly great.7 The cabinets of Europe can, as yet,
boast only of the larger species from tropical climates. It
is sufficient to disturb the composure of an entomologist's
mind, to look forward to the future dimensions of a com-
plete catalogue. The carnivorous beetles, or Carabidae, ap-
pear in extremely few numbers within the tropics: this is
the more remarkable when compared to the case of the car-
nivorous quadrupeds, which are so abundant in hot coun-
tries. I was struck with this observation both on entering
Brazil, and when I saw the many elegant and active forms
of the Harpalidse re-appearing on the temperate plains of

• Mr. Doubleday has lately described (before the Entomological Society,
March 3rd, 1845) a peculiar structure in the wings of this butterfly, which
seems to be the means of its making its noise. He says, " It is remarkable
for having a sort of drum at the base of the fore wings, between the costal
nervure and the subcostal. These two nervures, moreover, have a peculiar
screw-like diaphragm or vessel in the interior." I find in LangsdorfFs
travels (in the years 1803-7, P- 74) it is said, that in the island of St.
Catherine's on the coast of Brazil, a butterfly called Februa Hoffmanseggi,
makes a noise, when flying away, like a rattle.

7 1 may mention, as a common instance of one day's (June 23rd) col-
lecting, when I was not attending particularly to the Coleoptera, that I
caught sixty-eight species of that order. Among these, there were only
two of the Carabidae, four Brachelytra, fifteen Rhyncpphora, and fourteen
of the Chrysomelidae. Thirty-seven species of Arachnidae, which I brought
home, will be sufficient to prove that I was not paying overmuch attention
to the generally favoured order of Coleoptera.

La Plata. Do the very numerous spiders and rapacious
Hymenoptera supply the place of the carnivorous beetles?
The carrion-feeders and Brachelytra are very uncommon;
on the other hand, the Rhyncophora and Chrysomelidae, all
of which depend on the vegetable world for subsistence, are
present in astonishing numbers. I do not here refer to the
number of different species, but to that of the individual
insects; for on this it is that the most striking character in
the entomology of different countries depends. The orders
Orthoptera and Hemiptera are particularly numerous; as
likewise is the stinging division of the Hymenoptera ; the
bees, perhaps, being excepted. A person, on first entering a
tropical forest, is astonished at the labours of the ants : well-
beaten paths branch off in every direction, on which an army
of never-failing foragers may be seen, some going forth, and
others returning, burdened with pieces of green leaf, often
larger than their own bodies.

A small dark-coloured ant sometimes migrates in count-
less numbers. One day, at Bahia, my attention was drawn
by observing many spiders, cockroaches, and other insects,
and some lizards, rushing in the greatest agitation across
a bare piece of ground. A little way behind, every stalk and
leaf was blackened by a small ant. The swarm having
crossed the bare space, divided itself, and descended an old
wall. By this means many insects were fairly enclosed; and
the efforts which the poor little creatures made to extricate
themselves from such a death were wonderful. When the
ants came to the road they changed their course, and in
narrow files reascended the wall. Having placed a small
stone so as to intercept one of the lines, the whole body
attacked it, and then immediately retired. Shortly afterwards
another body came to the charge, and again having failed
to make any impression, this line of march was entirely
given up. By going an inch round, the file might have
avoided the stone, and this doubtless would have happened,
if it had been originally there : but having been attacked, the
lion-hearted little warriors scorned the idea of yielding.

Certain wasp-like insects, which construct in the corners
of the verandahs clay cells for their larvae, are very numer-
ous in the neighbourhood of Rio. These cells they stuff full

46 CHARLES DARWIN

of half-dead spiders and caterpillars, which they seem
wonderfully to know how to sting to that degree as to leave
them paralysed but alive, until their eggs are hatched; and
the larvae feed on the horrid mass of powerless, half-killed
victims — a sight which has been described by an enthusiastic
naturalist8 as curious and pleasing! I was much interested
one day by watching a deadly contest between a Pepsis and
a large spider of the genus Lycosa. The wasp made a sudden
dash at its prey, and then flew away: the spider was evi-
dently wounded, for, trying to escape, it rolled down a little
slope, but had still strength sufficient to crawl into a thick
tuft of grass. The wasp soon returned, and seemed sur-
prised at not immediately finding its victim. It then com-
menced as regular a hunt as ever hound did after fox;
making short semicircular casts, and all the time rapidly vi-
brating its wings and antennae. The spider, though well
concealed, was soon discovered; and the wasp, evidently still
afraid of its adversary's jaws, after much manoeuvring, in-
flicted two stings on the under side of its thorax. At last,
carefully examining with its antennae the now motionless
spider, it proceeded to drag away the body. But I stopped
both tyrant and prey."

The number of spiders, in proportion to other insects, is
here compared with England very much larger; perhaps
more so than with any other division of the articulate ani-
mals. The variety of species among the jumping spiders
appears almost infinite. The genus, or rather family, of
Epeira, is here characterized by many singular forms; some
species have pointed coriaceous shells, others enlarged and
spiny tibiae. Every path in the forest is barricaded with the
strong yellow web of a species, belonging to the same divi-
sion with the Epeira clavipes of Fabricius, which was for-
merly said by Sloane to make, in the West Indies, webs so
strong as to catch birds. A small and pretty kind of spider,

^_ r ,.«. u .. ...«..v »v. v_. .

probably of the same genus, says he saw it dragging a 'dead spider through
tall grass, in a straight line to its nest, which was one hundred and sixty-
three paces distant. He adds that the wasp, in order to find the road,
every now and then made " demi-tours d'environ trois palmes."

THE VOYAGE OF THE BEAGLE 47

with very long fore-legs, and which appears to belong to an
undescribed genus, lives as a parasite on almost every one
of these webs. I suppose it is too insignificant to be noticed
by the great Epeira, and is therefore allowed to prey on the
minute insects, which, adhering to the lines, would other-
wise be wasted. When frightened, this little spider either
feigns death by extending its front legs, or suddenly drops
from the web. A large Epeira of the same division with
Epeira tuberculata and conica is extremely common, espe-
cially in dry situations. Its web, which is generally placed
among the great leaves of the common agave, is sometimes
strengthened near the centre by a pair or even four zigzag
ribbons, which connect two adjoining rays. When any large
insect, as a grasshopper or wasp, is caught, the spider, by
a dexterous movement, makes it revolve very rapidly, and at
the same time emitting a band of threads from its spinners,
soon envelops its prey in a case like the cocoon of a silk-
worm. The spider now examines the powerless victim, and
gives the fatal bite on the hinder part of its thorax; then
retreating, patiently waits till the poison has taken effect.
The virulence of this poison may be judged of from the fact
that in half a minute I opened the mesh, and found a large
wasp quite lifeless. This Epeira always stands with its head
downwards near the centre of the web. When disturbed, it
acts differently according to circumstances: if there is a
thicket below, it suddenly falls down; and I have distinctly
seen the thread from the spinners lengthened by the animal
while yet stationary, as preparatory to its fall. If the ground
is clear beneath, the Epeira seldom falls, but moves quickly
through a central passage from one to the other side. When
still further disturbed, it practises a most curious manoeuvre :
standing in the middle, it violently jerks the web, which is
attached .to elastic twigs, till at last the whole acquires such
a rapid vibratory movement, that even the outline of the
spider's body becomes indistinct.

It is well known that most of the British spiders, when
a large insect is caught in their webs, endeavour to cut the
lines and liberate their prey, to save their nets from being
entirely spoiled. I once, however, saw in a hot-house in
Shropshire a large female wasp caught in the irregular web

48 CHARLES DARWIN

of a quite small spider ; and this spider, instead of cutting
the web, most perseveringly continued to entangle the body,
and especially the wings, of its prey. The wasp at first
aimed in vain repeated thrusts with its sting at its little
antagonist. Pitying the wasp, after allowing it to struggle
for more than an hour, I killed it and put it back into the
web. The spider soon returned; and an hour afterwards I
was much surprised to find it with its jaws buried in the
orifice, through which the sting is protruded by the living
wasp. I drove the spider away two or three times, but for
the next twenty-four hours I always found it again sucking
at the same place. The spider became much distended by the
juices of its prey, which was many times larger than itself.

I may here just mention, that I found, near St. Fe Bajada,
many large black spiders, with ruby-coloured marks on their
backs, having gregarious habits. The webs were placed verti-
cally, as is invariably the case with the genus Epeira: they
were separated from each other by a space of about two
feet, but were all attached to certain common lines, which
were of great length, and extended to all parts of the com-
munity. In this manner the tops of some large bushes were
encompassed by the united nets. Azara 10 has described a
gregarious spider in Paraguay, which Walckenaer thinks
must be a Theridion, but probably it is an Epeira, and perhaps
even the same species with mine. I cannot, however, recol-
lect seeing a central nest as large as a hat, in which, during
autumn, when the spiders die, Azara says the eggs are de-
posited. As al! the spiders which I saw were of the same
size, they must have been nearly of the same age. This
gregarious habit, in so typical a genus as Epeira, among
insects, which are so bloodthirsty and solitary that even the
two sexes attack each other, is a very singular fact.

In a lofty valley of the Cordillera, near Mendoza, I found
another spider with a singularly-formed web. Strong lines
radiated in a vertical plane from a common centre, where the
insect had its station; but only two of the rays were con-
nected by a symmetrical mesh-work ; so that the net, instead of
being, as is generally the case, circular, consisted of a wedge-
shaped segment. All the webs were similarly constructed.

yULY ^th, 1832. — In the morning we got under way, and
stood out of the splendid harbour of Rio de Janeiro.
In our passage to the Plata, we saw nothing particular,
excepting on one day a great shoal of porpoises, many hun-
dreds in number. The whole sea was in places furrowed by
them ; and a most extraordinary spectacle was presented, as
hundreds, proceeding together by jumps, in which their
whole bodies were exposed, thus cut the water. When the
ship was running nine knots an hour, these animals could
cross and recross the bows with the greatest ease, and then
dash away right ahead. As soon as we entered the estuary
of the Plata, the weather was very unsettled. One dark
night we were surrounded by numerous seals and penguins,
which made such strange noises, that the officer on watch
reported he could hear the cattle bellowing on shore. On
a second night we witnessed a splendid scene of natural fire-
works; the mast-head and yard-arm-ends shone with St.
Elmo's light ; and the form of the vane could almost be
traced, as if it had been rubbed with phosphorus. The sea
was so highly luminous, that the tracks of the penguins were
marked by a fiery wake, and the darkness of the sky was
momentarily illuminated by the most vivid lightning.

When within the mouth of the river, I was interested by
observing how slowly the waters of the sea and river mixed.
The latter, muddy and discoloured, from its less specific
gravity, floated on the surface of the salt water. This was
curiously exhibited in the wake of the vessel, where a line

SO CHARLES DARWIN

of blue water was seen mingling in little eddies, with the
adjoining fluid.

July 26th. — We anchored at Monte Video. The Beagle
was employed in surveying the extreme southern and eastern
coasts of America, south of the Plata, during the two suc-
ceeding years. To prevent useless repetitions, I will extract
those parts of my journal which refer to the same districts,
without always attending to the order in which we visited
them.

MALDONADO is situated on the northern bank of the Plata,
and not very far from the mouth of the estuary. It is a
most quiet, forlorn, little town; built, as is universally the
case in these countries, with the streets running at right
angles to each other, and having in the middle a large plaza
or square, which, from its size, renders the scantiness of the
population more evident. It possesses scarcely any trade;
the exports being confined to a few hides and living cattle.
The inhabitants are chiefly landowners, together with a few
shopkeepers and the necessary tradesmen, such as black-
smiths and carpenters, who do nearly all the business for a
circuit of fifty miles round. The town is separated from the
river by a band of sand-hillocks, about a mile broad: it is
surrounded, on all other sides, by an open slightly-undulat-
ing country, covered by one uniform layer of fine green turf,
on which countless herds of cattle, sheep, and horses graze.
There is very little land cultivated even close to the town.
A few hedges, made of cacti and agave, mark out where
some wheat or Indian corn has been planted. The features
of the country are very similar along the whole northern
bank of the Plata. The only difference is, that here the
granitic hills are a little bolder. The scenery is very unin-
teresting; there is scarcely a house, an enclosed piece of
ground, or even a tree, to give it an air of cheerfulness.
Yet, after being imprisoned for some time in a ship, there is
a charm in the unconfined feeling of walking over boundless
plains of turf. Moreover, if your view is limited to a small
space, many objects possess beauty. Some of the smaller
birds are brilliantly coloured; and the bright green sward,
brov/sed short by the cattle, is ornamented by dwarf flow-

THE VOYAGE OF THE BEAGLE 51

ers, among which a plant, looking like the daisy, claimed the
place of an old friend. What would a florist say to whole
tracts, so thickly covered by the Verbena melindres, as, even
at a distance, to appear of the most gaudy scarlet?

I stayed ten weeks at Maldonado, in which time a nearly
perfect collection of the animals, birds, and reptiles, was
procured. Before making any observations respecting them,
I will give an account of a little excursion I made as far
as the river Polanco, which is about seventy miles distant,
in a northerly direction. I may mention, as a proof how
cheap everything is in this country, that I paid only two
dollars a day, or eight shillings, for two men, together with
a troop of about a dozen riding-horses. My companions
were well armed with pistols and sabres ; a precaution which
I thought rather unnecessary; but the first piece of news
we heard was, that, the day before, a traveller from Monte
Video had been found dead on the road, .with his throat
cut. This happened close to a cross, the record of a former
murder.

On the first night we slept at a retired little country-
house; and there I soon found out that I possessed two or
three articles, especially a pocket compass, which created
unbounded astonishment. In every house I was asked to
show the compass, and by its aid, together with a map, to
point out the direction of various places. It excited the live-
liest admiration that I, a perfect stranger, should know the
road (for direction and road are synonymous in this open
country) to places where I had never been. At one house
a young woman, who was ill in bed, sent to entreat me to
come and show her the compass. If their surprise was great,
mine was greater, to find such ignorance among people who
possessed their thousands of cattle, and " estancias " of great
extent. It can only be accounted for by the circumstance
that this retired part of the country is seldom visited by
foreigners. I was asked whether the earth or sun moved;
whether it was hotter or colder to the north; where Spain
was, and many other such questions. The greater number of
the inhabitants had an indistinct idea that England, London,
and North America, were different names for the same
place; but the better informed well knew that London and

52 CHARLES DARWIN

North America were separate countries close together, and
that England was a large town in London ! I carried with
me some promethean matches, which I ignited by biting; it
was thought so wonderful that a man should strike fire with
his teeth, that it was usual to collect the whole family to see
it: I was once offered a dollar for a single one. Washing
my face in the morning caused much speculation at the vil-
lage of Las Minas; a superior tradesman closely cross-ques-
tioned me about so singular a practice ; and likewise why on
board we wore our beards ; for he had heard from my guide
that we did so. He eyed me with much suspicion; perhaps
he had heard of ablutions in the Mahomedan religion, and
knowing me to be a heretick, probably he came to the con-
clusion that all hereticks were Turks. It is the general cus-
tom in this country to ask for a night's lodging at the first
convenient house. The astonishment at the compass, and
my other feats of jugglery, was to a certain degree advan-
tageous, as with that, and the long stories my guides told
of my breaking stones, knowing venomous from harmless
snakes, collecting insects, etc., I repaid them for their hospi-
tality. I am writing as if I had been among the inhabitants
of central Africa: Banda Oriental would not be flattered by
the comparison ; but such were my feelings at the time.

The next day we rode to the village of Las Minas. The
country was rather more hilly, but otherwise continued the
same; an inhabitant of the Pampas no doubt would have
considered it as truly Alpine. The country is so thinly in-
habited, that during the whole day we scarcely met a single
person. Las Minas is much smaller even than Maldonado.
It is seated on a little plain, and is surrounded by low rocky
mountains. It is of the usual symmetrical form; and with
its whitewashed church standing in the centre, had rather
a pretty appearance. The outskirting houses rose out of the
plain like isolated beings, without the accompaniment of
gardens or courtyards. This is generally the case in the
country, and all the houses have, in consequence, an uncom-
fortable aspect. At night we stopped at a pulperia, or drink-
ing-shop. During the evening a great number of Gauchos
came in to drink spirits and smoke cigars: their appearance
is very striking; they are generally tall and handsome, but

THE VOYAGE OF THE BEAGLE S3

with a proud and dissolute expression of countenance. They
frequently wear their moustaches and long black hair curl-
ing down their backs. With their brightly coloured gar-
ments, great spurs clanking about their heels, and knives
stuck as daggers (and often so used) at their waists, they
look a very different race of men from what might be ex-
pected from their name of Gauchos, or simple countrymen.
Their politeness is excessive; they never drink their spirits
without expecting you to taste it; but whilst making their
exceedingly graceful bow, they seem quite as' ready, if occa-
sion offered, to cut your throat.

On the third day we pursued rather an irregular course,
as I was employed in examining some beds of marble. On
the fine plains of turf we saw many ostriches (Struthio
rhea). Some of the flocks contained as many as twenty or
thirty birds. These, when standing on any little eminence,
and seen against the clear sky, presented a very noble ap-
pearance. I never met with such tame ostriches in any other
part of the country: it was easy to gallop up within a short
distance of them; but then, expanding their wings, they
made all sail right before the wind, and soon left the horse
astern.

At night we came to the house of Don Juan Fuentes, a
rich landed proprietor, but not personally known to either
of my companions. On approaching the house of a stranger,
it is usual to follow several little points of etiquette: riding
up slowly to the door, the salutation of Ave Maria is given,
and until somebody comes out and asks you to alight, it is
not customary even to get off your horse : the formal answer
of the owner is, " sin pecado concebida " — that is, conceived
without sin. Having entered the house, some general con-
versation is kept up for a few minutes, till permission is
asked to pass the night there. This is granted as a matter
of course. The stranger then takes his meals with the family,
and a room is assigned him, where with the horsecloths be-
longing to his recado (or saddle of the Pampas) he makes
his bed. It is curious how similar circumstances produce
such similar results in manners. At the Cape of Good Hope
the same hospitality, and very nearly the same points of eti-
quette, are universally observed. The difference, however,

54 CHARLES DARWIN

between the character of the Spaniard and that of the Dutch
boer is shown, by the former never asking his guest a single
question beyond the strictest rule of politeness, whilst the
honest Dutchman demands where he has been, where he is
going, what is his business, and even how many brothers,
sisters, or children he may happen to have.

Shortly after our arrival at Don Juan's, one of the largest
herds of cattle was driven in towards the house, and three
beasts were picked out to be slaughtered for the supply of
the establishment. These half-wild cattle are very active;
and knowing full well the fatal lazo, they led the horses a
long and laborious chase. After witnessing the rude wealth
displayed in the number of cattle, men, and horses, Don
Juan's miserable house was quite curious. The floor con-
sisted of hardened mud, and the windows were without
glass; the sitting-room boasted only of a few of the roughest
chairs and stools, with a couple of tables. The supper, al-
though several strangers were present, consisted of two huge
piles, one of roast beef, the other of boiled, with some pieces
of pumpkin : besides this latter there was no other vegetable,
and not even a morsel of bread. For drinking, a large
earthenware jug of water served the whole party. Yet this
man was the owner of several square miles of land, of which
nearly every acre would produce corn, and, with a little trou-
ble, all the common vegetables. The evening was spent in
smoking, with a little impromptu singing, accompanied by
the guitar. The signoritas all sat together in one corner
of the room, and did not sup with the men.

So many works have been written about these countries,
that it is almost superfluous to describe either the lazo or
the bolas. The lazo consists of a very strong, but thin, well-
plaited rope, made of raw hide. One end is attached to the
broad surcingle, which fastens together the complicated gear
of the recado, or saddle used in the Pampas; the other is
terminated by a small ring of iron or brass, by which a noose
can be formed. The Gaucho, when he is going to use the
lazo, keeps a small coil in his bridle-hand, and in the other
holds the running noose, which is made very large, gener-
ally having a diameter of about eight feet. This he whirls
round his head, and bv the dexterous movement of his wrist

THE VOYAGE OF THE BEAGLE 55

keeps the noose open ; then, throwing it, he causes it to fall
on any particular spot he chooses. The lazo, when not used,
is tied up in a small coil to the after part of the recado.
The bolas, or balls, are of two kinds: the simplest, which
is chiefly used for catching ostriches, consists of two round
stones, covered with leather, and united by a thin plaited
thong, about eight feet long. The other kind differs only
in having three balls united by the thongs to a common
centre. The Gaucho holds the smallest of the three in his
hand, and whirls the other two round and round his head;
then, taking aim, sends them like chain shot revolving
through the air. The balls no sooner strike any object, than,
winding round it, they cross each other, and become firmly
hitched. The size and weight of the balls vary, according
to the purpose for which they are made : when of stone,
although not larger than an apple, they are sent with such
force as sometimes to break the leg even of a horse. I have
seen the balls made of wood, and as large as a turnip, for
the sake of catching these animals without injuring them.
The balls are sometimes made of iron, and these can be
hurled to the greatest distance. The main difficulty in using
either lazo or bolas is to ride so well as to be able at full
speed, and while suddenly turning about, to whirl them so
steadily round the head, as to take aim : on foot any person
would soon learn the art. One day, as I was amusing myself
by galloping and whirling the balls round my head, by acci-
dent the free one struck a bush ; and its revolving motion
being thus destroyed, it immediately fell to the ground, and,
like magic, caught one hind leg of my horse; the other ball
was then jerked out of my hand, and the horse fairly se-
cured. Luckily he was an old practised animal, and knew
what it meant ; otherwise he would probably have kicked
till he had thrown himself down. The Gauchos roared with
laughter; they cried out that they had seen every sort of ani-
mal caught, but had never before seen a man caught by
himself.

During the two succeeding days, I reached the furthest
point which I was anxious to examine. The country wore.
the same aspect, till at last the fine green turf became more
.wearisome than a dusty turnpike road. We everywhere saw

56 CHARLES DARWIN

great numbers of partridges (Nothura major). These birds
do not go in coveys, nor do they conceal themselves like
the English kind. It appears a very silly bird. A man on
horseback by riding round and round in a circle, or rather
in a spire, so as to approach closer each time, may knock
on the head as many as he pleases. The more common
method is to catch them with a running noose, or little lazo,
made of the stem of an ostrich's feather, fastened to the
end of a long stick. A boy on a quiet old horse will fre-
quently thus catch thirty or forty in a day. In Arctic North
America1 the Indians catch the Varying Hare by walking
spirally round and round it, when on its form: the middle
of the day is reckoned the best time, when the sun is high,
and the shadow of the hunter not very long.

On our return to Maldonado, we followed rather a differ-
ent line of road. Near Pan de Azucar, a landmark well
known to all those who have sailed up the Plata, I stayed
a day at the house of a most hospitable old Spaniard. Early
in the morning we ascended the Sierra de las Animas. By
the aid of the rising sun the scenery was almost picturesque.
To the westward the view extended over an immense level
plain as far as the Mount, at Monte Video, and to the east-
ward, over the mammillated country of Maldonado. On
the summit of the mountain there were several small heaps
of stones, which evidently had lain there for many years.
My companion assured me that they were the work of the
Indians in the old time. The heaps were similar, but on
a much smaller scale, to those so commonly found on the
mountains of Wales. The desire to signalize any event, on
the highest point of the neighbouring land, seems an uni-
versal passion with mankind. At the present day, not a
single Indian, either civilized or wild, exists in this part
of the province ; nor am I aware that the former inhabitants
have left behind them any more permanent records than
these insignificant piles on the summit of the Sierra de las
Animas.

The general, and almost entire absence of trees in Banda
Oriental is remarkable. Some of the rocky hills are partly

1 Hearne's Journey, p. 383.

THE VOYAGE OF THE BEAGLE 57

covered by thickets, and on the banks of the larger streams,
especially to the north of Las Minas, willow-trees are not
uncommon. Near the Arroyo Tapes I heard of a wood of
palms; and one of these trees, of considerable size, I saw
near the Pan de Azucar, in lat. 35°. These, and the trees
planted by the Spaniards, offer the only exceptions to the
general scarcity of wood. Among the introduced kinds may
be enumerated poplars, olives, peach, and other fruit trees:
the peaches succeed so well, that they afford the main supply
of firewood to the city of Buenos Ayres. Extremely level
countries, such as the Pampas, seldom appear favourable to
the growth of trees. This may possibly be attributed either
to the force of the winds, or the kind of drainage. In the
nature of the land, however, around Maldonado, no such
reason is apparent; the rocky mountains afford protected
situations, enjoying various kinds of soil; streamlets of
water are common at the bottoms of nearly every valley;
and the clayey nature of the earth seems adapted to retain
moisture. It has been inferred with much probability, that
the presence of woodland is generally determined2 by the
annual amount of moisture; yet in this province abundant
and heavy rain falls during the winter; and the summer,
though dry, is not so in any excessive degree.3 We see nearly
the whole of Australia covered by lofty trees, yet that coun-
try possesses a far more arid climate. Hence we must look
to some other and unknown cause.

Confining our view to South America, we should certainly
be tempted to believe that trees flourished only under a very
humid climate; for the limit of the forest-land follows, in a
most remarkable manner, that of the damp winds. In the
southern part of the continent, where the western gales,
charged with moisture from the Pacific, prevail, every island
on the broken west coast, from lat. 38° to the extreme point
of Tierra del Fuego, is densely covered by impenetrable for-
ests. On the eastern side. of the Cordillera, over the same
extent of latitude, where a blue sky and a fine climate prove
that the atmosphere has been deprived of its moisture by
passing over the mountains, the arid plains of Patagonia

3 Azara says, " Je crois que la quantite annuelle des pluies est, dans
toutes ces contrees, plus considerable qu'en Espagne." — Vol. ». p. 36-

58 CHARLES DARWIN

support a most scanty vegetation. In the more northern
parts of the continent, within the limits of the constant
south-eastern trade-wind, the eastern side is ornamented by
magnificent forests ; whilst the western coast, from lat. 4° S.
to lat. 32° S., may be described as a desert; on this western
coast, northward of lat. 4° S., where the trade-wind loses its
regularity, and heavy torrents of rain fall periodically, the
shores of the Pacific, so utterly desert in Peru, assume near
Cape Blanco the character of luxuriance so celebrated at
Guyaquil and Panama. Hence in the southern and northern
parts of the continent, the forest and desert lands occupy
reversed positions with respect to the Cordillera, and these
positions are apparently determined by the direction of the
prevalent winds. In the middle of the continent there is a
broad intermediate band, including central Chile and the
provinces of La Plata, where the rain-bringing winds have
not to pass over lofty mountains, and where the land is nei-
ther a desert nor covered by forests. But even the rule, if
confined to South America, of trees flourishing only in a
climate rendered humid by rain-bearing winds, has a strongly
marked exception in the case of the Falkland Islands. These
islands, situated in the same latitude with Tierra del Fuego
and only between two and three hundred miles distant from
it, having a nearly similar climate, with a geological forma-
tion almost identical, with favourable situations and the
same kind of peaty soil, yet can boast of few plants deserv-
ing even the title of bushes ; whilst in Tierra del Fuego it is
impossible to find an acre of land not covered by the densest
forest. In this case, both the direction of the heavy gales
of wind and of the currents of the sea are favourable to
the transport of seeds from Tierra del Fuego, as is shown
by the canoes and trunks of trees drifted from that country,
and frequently thrown on the shores of the Western Falk-
land. Hence perhaps it is, that there are many plants in
common to the two countries: but with respect to the trees
of Tierra del Fuego, even attempts made to transplant them
have failed.

During our stay at Maldonado I collected several quad-
rupeds, eighty kinds of birds, and many reptiles, including
nine species of snakes. Of the indigenous mammalia, the

THE VOYAGE OF THE BEAGLE 59

only one now left of any size, which is common, is the Cervus
campestris. This deer is exceedingly abundant, often in
small herds, throughout the countries bordering the Plata
and in Northern Patagonia. If a person crawling close along
the ground, slowly advances towards a herd, the deer fre-
quently, out of curiosity, approach to reconnoitre him. I
have by this means, killed from one spot, three out of the
same herd. Although so tame and inquisitive, yet when ap-
proached on horseback, they are exceedingly wary. In this
country nobody goes on foot, and the deer knows man as its
enemy only when he is mounted and armed with the bolas.
At Bahia Blanca, a recent establishment in Northern Pata-
gonia, I was surprised to find how little the deer cared for
the noise of a gun: one day I fired ten times from within
eighty yards at one animal; and it was much more startled
at the ball cutting up the ground than at the report of
the rifle. My powder being exhausted, I was obliged to
get up (to my shame as a sportsman be it spoken, though
well able to kill birds on the wing) and halloo till the deer
ran away.

The most curious fact with respect to this animal, is the
overpoweringly strong and offensive odour which proceeds
from the buck. It is quite indescribable: several times
whilst skinning the specimen which is now mounted at the
Zoological Museum, I was almost overcome by nausea. I
tied up the skin in a silk pocket-handkerchief, and so carried
it home : this handkerchief, after being well washed, I con-
tinually used, and it was of course as repeatedly washed ; yet
every time, for a space of one year and seven months, when
first unfolded, I distinctly perceived the odour. This ap-
pears an astonishing instance of the permanence of some
matter, which nevertheless in its nature must be most subtile
and volatile. Frequently, when passing at the distance of
half a mile to leeward of a herd, I have perceived the whole
air tainted with the effluvium. I believe the smell from the
buck is most powerful at the period when its horns are per-
fect, or free from the hairy skin. When in this state the
meat is, of course, quite uneatable; but the Gauchos assert,
that if buried for some time in fresh earth, the taint is re-
moved. I have somewhere read that the islanders in the

60 CHARLES DARWIN

north of Scotland treat the rank carcasses of the fish-eating
birds in the same manner.

The order Rodentia is here very numerous in species:
of mice alone I obtained no less than eight kinds.* The
largest gnawing animal in the world, the Hydrochserus capy-
bara (the water-hog), is here also common. One which I
shot at Monte Video weighed ninety-eight pounds: its
length, from the end of the snout to the stump-like tail, was
three feet two inches; and its girth three feet eight. These
great Rodents occasionally frequent the islands in the mouth
of the Plata, where the water is quite salt, but are far more
abundant on the borders of fresh-water lakes and rivers.
Near Maldonado three or four generally live together. In
the daytime they either lie among the aquatic plants, or
openly feed on the turf plain.6 When viewed at a distance,
from their manner of walking and colour they resemble pigs :
but when seated on their haunches, and attentively watch-
ing any object with one eye, they reassume the appearance
of their congeners, cavies and rabbits. Both the front and
side view of their head has quite a ludicrous aspect, from
the great depth of their jaw. These animals, at Maldonado,
were very tame ; by cautiously walking, I approached within
three yards of four old ones. This tameness may probably
be accounted for, by the Jaguar having been banished for
some years, and by the Gaucho not thinking it worth his
while to hunt them. As I approached nearer and nearer
they frequently made their peculiar noise, which is a low
abrupt grunt, not having much actual sound, but rather aris-
ing from the sudden expulsion of air : the only noise I know
at all like it, is the first hoarse bark of a large dog. Having
watched the four from almost within arm's length (and they
me) for several minutes, they rushed into the water at full

* In South America I collected altogether twenty-seven species of mice,
and thirteen more are known from the works of Azara ana other authors.
Those collected by myself have been named and described by Mr. Water-
house at the meetings of the Zoological Society. I must be allowed to take
this opportunity of returning my cordial thanks to Mr. Waterhouse, and
to the other gentlemen attached to that Society, for their kind and most
liberal assistance on all occasions.

B In the stomach and duodenum of a capybara which I opened I found
a very large quantity of a thin yellowish fluid, in which scarcely a fibre
could be distinguished. Mr. Owen informs me that a part of the oesophagus
is so constructed that nothing much larger than a crowquill can be passed
down. Certainly the broad teeth and strong jaws of this animal are well
fitted to grind into pulp the aquatic plants on which it feeds.

THE VOYAGE OF THE BEAGLE 61

gallop with the greatest impetuosity, and emitted at the
same time their bark. After diving a short distance they
came again to the surface, but only just showed the upper
part of their heads. When the female is swimming in the
water, and has young ones, they are said to sit on her back.
These animals are easily killed in numbers ; but their skins
are of trifling value, and the meat is very indifferent. On
the islands in the Rio Parana they are exceedingly abundant,
and afford the ordinary prey to the Jaguar.

The Tucutuco (Ctenomys Brasiliensis) is a curious small
animal, which may be briefly described as a Gnawer, with
the habits of a mole. It is extremely numerous in some
parts of the country, but it is difficult to be procured, and
never, I believe, comes out of the ground. It throws up at
the mouth of its burrows hillocks of earth like those of the
mole, but smaller. Considerable tracts of country are so
completely undermined by these animals, that horses in pass-
ing over, sink above their fetlocks. The tucutucos appear,
to a certain degree, to be gregarious : the man who pro-
cured the specimens for me had caught six together, and he
said this was a common occurrence. They are nocturnal in
their habits; and their principal food is the roots of plants,
which are the object of their extensive and superficial bur-
rows. This animal is universally known by a very peculiar
noise which it makes when beneath the ground. A person,
the first time he hears it, is much surprised; for it is not
easy to tell whence it comes, nor is it possible to guess what
kind of creature utters it. The noise consists in a short, but
not rough, nasal grunt, which is monotonously repeated
about four times in quick succession :8 the name Tucutuco is
given in imitation of the sound. Where this animal is
abundant, it may be heard at all times of the day, and some-
times directly beneath one's feet. When kept in a room, the
tucutucos move both slowly and clumsily, which appears
owing to the outward action of their hind legs ; and they are

•At the R. Negro, in Northern Patagonia, there is an animal of the
same habits, and probably a closely allied species, but which I never saw.
Its noise is different from that of the Maldonado kind; it is repeated only
twice instead of three or four times, and is more distinct and sonorous;
when heard from a distance it so closely resembles the sound made in cut-
ting down a small tree with an axe, that I have sometimes remained in
doubt concerning it.

quite incapable, from the socket of the thigh-bone not hav-
ing a certain ligament, of jumping even the smallest vertical
height. They are very stupid in making any attempt to
escape ; when angry or frightened they utter the tucutuco.
Of those I kept alive several, even the first day, became
quite tame, not attempting to bite or to run away; others
were a little wilder.

The man who caught them asserted that very many are
invariably found blind. A specimen which I preserved in
spirits was in this state ; Mr. Reid considers it to be the effect
of inflammation in the nictitating membrane. When the
animal was alive I placed my finger within half an inch of
its head, and not the slightest notice was taken: it made its
way, however, about the room nearly as well as the others.
Considering the strictly subterranean habits of the tucutuco,
the blindness, though so common, cannot be a very serious
evil; yet it appears strange that any animal should possess
an organ frequently subject to be injured. Lamarck would
have been delighted with this fact, had he known it, when
speculating7 (probably with more truth than usual with him)
on the gradually acquired blindness of the Asphalax, a
Gnawer living under ground, and of the Proteus, a reptile
living in dark caverns filled with water; in both of which
animals the eye is in an almost rudimentary state, and is
covered by a tendinous membrane and skin. In the common
mole the eye is extraordinarily small but perfect, though
many anatomists doubt whether it is connected with the true
optic nerve; its vision must certainly be imperfect, though
probably useful to the animal when it leaves its burrow. In
the tucutuco, which I believe never comes to the surface of
the ground, the eye is rather larger, but often rendered blind
and useless, though without apparently causing any incon-
venience to the animal; no doubt Lamarck would have said
that the tucutuco is now passing into the state of the
Asphalax and Proteus.

Birds of many kinds are extremely abundant on the undu-
lating grassy plains around Maldonado. There are several
species of a family allied in structure and manners to our
Starling: one of these (Molothrus niger) is remarkable from

7 Philosoph. Zoolog.. torn. i. p. 242.

THE VOYAGE OF THE BEAGLE 63

its habits. Several may often be seen standing together on
the back of a cow or horse; and while perched on a hedge,
pluming themselves in the sun, they sometimes attempt to
sing, or rather to hiss ; the noise being very peculiar, resem-
bling that of bubbles of air passing rapidly from a small
orifice under water, so as to produce an acute sound. Ac-
cording to Azara, this bird, like the cuckoo, deposits its eggs
in other birds' nests. I was several times told by the coun-
try people that there certainly is some bird having this
habit ; and my assistant in collecting, who is a very accurate
person, found a nest of the sparrow of this country (Zono-
trichia matutina), with one egg in it larger than the others,
and of a different colour and shape. In North America
there is another species of Molothrus (M. pecoris), which
has a similar cuckoo-like habit, and which is most closely
allied in every respect to the species from the Plata, even in
such trifling peculiarities as standing on the backs of cattle;
it differs only in being a little smaller, and in its plumage
and eggs being of a slightly different shade of colour. This
close agreement in structure and habits, in representative
species coming from opposite quarters of a great conti-
nent, always strikes one as interesting, though of common
occurrence.

Mr. Swainson has well remarked,8 that with the excep-
tion of the Molothrus pecoris, to which must be added the
M. niger, the cuckoos are the only birds which can be called
truly parasitical ; namely, such as " fasten themselves, as it
were, on another living animal, whose animal heat brings
their young into life, whose food they live upon, and whose
death would cause theirs during the period of infancy." It
is remarkable that some of the species, but not all, both of
the Cuckoo and Molothrus, should agree in this one strange
habit of their parasitical propagation, whilst opposed to each
other in almost every other habit: the molothrus, like our
starling, is eminently sociable, and lives on the open plains
without art or disguise: the cuckoo, as every one knows,
is a singularly shy bird ; it frequents the most retired thick-
ets, and feeds on fruit and caterpillars. In structure also
these two genera are widely removed from each other.

Many theories, even phrenological theories, have been ad-
vanced to explain the origin of the cuckoo laying its eggs in
other birds' nests. M. Prevost alone, I think, has thrown
light by his observations9 on this puzzle: he finds that the
female cuckoo, which, according to most observers, lays at
least from four to six eggs, must pair with the male each time
after laying only one or two eggs. Now, if the cuckoo was
obliged to sit on her own eggs, she would either have to sit
on all together, and therefore leave those first laid so long,
that they probably would become addled; or she would have
to hatch separately each egg, or two eggs, as soon as laid :
but as the cuckoo stays a shorter time in this country than
any other migratory bird, she certainly would not have time
enough for the successive hatchings. Hence we can perceive
in the fact of the cuckoo pairing several times, and laying
her eggs at intervals, the cause of her depositing her eggs
in other birds' nests, and leaving them to the care of foster-
parents. I am strongly inclined to believe that this view is
correct, from having been independently led (as we shall
hereafter see) to an analogous conclusion with regard to
the South American ostrich, the females of which are
parasitical, if I may so express it, on each other; each
female laying several eggs in the nests of several other
females, and the male ostrich undertaking all the cares
of incubation, like the strange foster-parents with the
cuckoo.

I will mention only two other birds, which are very com-
mon, and render themselves prominent from their habits.
The Saurophagus sulphuratus is typical of the great Ameri-
can tribe of tyrant-flycatchers. In its structure it closely
approaches the true shrikes, but in its habits may be com-
pared to many birds. I have frequently observed it, hunting
a field, hovering over one spot like a hawk, and then pro-
ceeding on to another. When seen thus suspended in the air,
it might very readily at a short distance be mistaken for one
of the Rapacious order; its stoop, however, is very inferior
in force and rapidity to that of a hawk. At other times
the Saurophagus haunts the neighbourhood of water, and
there, like a kingfisher, remaining stationary, it catches any

THE VOYAGE OF THE BEAGLE 65

small fish which may come near the margin. These birds are
not unfrequently kept either in cages or in courtyards, with
their wings cut. They soon become tame, and are very
amusing from their cunning odd manners, which were
described to me as being similar to those of the common
magpie. Their flight is undulatory, for the weight of the
head and bill appears too great for the body. In the
evening the Saurophagus takes its stand on a bush, often
by the roadside, and continually repeats without a change
a shrill and rather agreeable cry, which somewhat resem-
bles articulate words: the Spaniards say it is like the words
" Bien te veo" (I see you well), and accordingly have given
it this name.

A mocking-bird (Mimus orpheus), called by the inhabi-
tants Calandria, is remarkable, from possessing a song far
superior to that of any other bird in the country: indeed, it
is nearly the only bird in South America which I have
observed to take its stand for the purpose of singing. The
song may be compared to that of the Sedge warbler, but
is more powerful; some harsh notes and some very high
ones, being mingled with a pleasant warbling. It is heard
only during the spring. At other times its cry is harsh and
far from harmonious. Near Maldonado these birds were
tame and bold; they constantly attended the country houses
in numbers, to pick the meat which was hung up on the posts
or walls: if any other small bird joined the feast, the Calan-
dria soon chased it away. On the wide uninhabited plains
of Patagonia another closely allied species, O. Patagonica
of d'Orbigny, which frequents the valleys clothed with
spiny bushes, is a wilder bird, and has a slightly different
tone of voice. It appears to me a curious circumstance, as
showing the fine shades of difference in habits, that judging
from this latter respect alone, when I first saw this second
species, I thought it was different from the Maldonado kind.
Having afterwards procured a specimen, and comparing the
two without particular care, they appeared so very similar,
that I changed my opinion ; but now Mr. Gould says that they
are certainly distinct; a conclusion in conformity with the
trifling difference of habit, of which, of course, he was not
aware.

The number, lameness, and disgusting habits of the car-
rion-feeding hawks of South America make them pre-emi-
nently striking to any one accustomed only to the birds of
Northern Europe. In this list may be included four species
of the Caracara or Polyborus, the Turkey buzzard, the Gal-
linazo, and the Condor. The Caracaras are, from their
structure, placed among the eagles: we shall soon see how
ill they become so high a rank. In their habits they well
supply the place of our carrion-crows, magpies, and ravens ;
a tribe of birds widely distributed over the rest of the world,
but entirely absent in South America. To begin with the
Polyborus Brasiliensis : this is a common bird, and has a wide
geographical range ; it is most numerous on the grassy savan-
nahs of La Plata (where it goes by the name of Carrancha),
and is far from unfrequent throughout the sterile plains of
Patagonia. In the desert between the rivers Negro and Col-
orado, numbers constantly attend the line of road to devour
the carcasses of the exhausted animals which chance to
perish from fatigue and thirst. Although thus common in
these dry and open countries, and likewise on the arid shores
of the Pacific, it is nevertheless found inhabiting the damp
impervious forests of West Patagonia and Tierra del Fuego.
The Carranchas, together with the Chimango, constantly
attend in numbers the estancias and slaughtering-houses. If
an animal dies on the plain the Gallinazo commences the
feast, and then the two species of Polyborus pick the bones
clean. These birds, although thus commonly feeding to-
gether, are far from being friends. When the Carrancha is
quietly seated on the branch of a tree or on the ground, the
Chimango often continues for a long time flying backwards
and forwards, up and down, in a semicircle, trying each time
at the bottom of the curve to strike its larger relative. The
Carrancha takes little notice, except by bobbing its head.
Although the Carranchas frequently assemble in numbers,
they are not gregarious; for in desert places they may be
seen solitary, or more commonly by pairs.

The Carranchas are said to be very crafty, and to steal
great numbers of eggs. They attempt, also, together with
the Chimango, to pick off the scabs from the sore backs of
horses and mules. The poor animal, on the one hand, with

THE VOYAGE OF THE BEAGLE 67

its ears down and its back arched; and, on the other, the
hovering bird, eyeing at the distance of a yard the disgust-
ing morsel, form a picture, which has been described by Cap-
tain Head with his own peculiar spirit and accuracy. These
false eagles most rarely kill any living bird or animal ; and
their vulture-like, necrophagous habits are very evident to
any one who has fallen asleep on the desolate plains of Pata-
gonia, for when he wakes, he will see, on each surrounding
hillock, one of these birds patiently watching him with an
evil eye: it is a feature in the landscape of these coun-
tries, which will be recognised by every one who has wan-
dered over them. If a party of men go out hunting with dogs
and horses, they will be accompanied, during the day, by
several of these attendants. After feeding, the uncovered
craw protrudes; at such times, and indeed generally, the
Carrancha is an inactive, tame, and cowardly bird. Its
flight is heavy and slow, like that of an English rook. It
seldom soars ; but I have twice seen one at a great height
gliding through the air with much ease. It runs (in con-
tradistinction to hopping), but not quite so quickly as some
of its congeners. At times the Carrancha is noisy, but is
not generally so : its cry is loud, very harsh and peculiar, and
may be likened to the sound of the Spanish guttural g, fol-
lowed by a rough double r r; when uttering this cry it
elevates its head higher and higher, till at last, with its
beak wide open, the crown almost touches the lower part of
the back. This fact, which has been doubted, is quite true;
I have seen them several times with their heads backwards
in a completely inverted position. To these observations I
may add, on the high authority of Azara, that the Carrancha
feeds on worms, shells, slugs, grasshoppers, and frogs; that
it destroys young lambs by tearing the umbilical cord; and
that it pursues the Gallinazo, till that bird is compelled to
vomit up the carrion it may have recently gorged. Lastly,
Azara states that several Carranchas, five or six together,
will unite in chase of large birds, even such as herons. All
these facts show that it is a bird of very versatile habits and
considerable ingenuity.

The Polyborus Chimango is considerably smaller than the
last species. It is truly omnivorous, and will eat even bread;

68 CHARLES DARWIN

and I was assured that it materially injures the potato-crops
in Chiloe, by stocking up the roots when first planted. Of
all the carrion-feeders it is generally the last which leaves
the skeleton of a dead animal, and may often be seen within
the ribs of a cow or horse, like a bird in a cage. Another
species is the Polyborus Novae Zelandiae, which is exceed-
ingly common in the Falkland Islands. These birds in many
respects resemble in their habits the Carranchas. They live
on the flesh of dead animals and on marine productions ; and
on the Ramirez rocks their whole sustenance must depend
on the sea. They are extraordinarily tame and fearless, and
haunt the neighborhood of houses for offal. If a hunting
party kills an animal, a number soon collect and patiently
await, standing on the ground on all sides. After eating,
their uncovered craws are largely protruded, giving them a
disgusting appearance. They readily attack wounded birds:
a cormorant in this state having taken to the shore, was
immediately seized on by several, and its death hastened
by their blows. The Beagle was at the Falklands only
during the summer, but the officers of the Adventure, who
were there in the winter, mention many extraordinary in-
stances of the boldness and rapacity of these birds. They
actually pounced on a dog that was lying fast asleep close
by one of the party ; and the sportsmen had difficulty in pre-
venting the wounded geese from being seized before their
eyes. It is said that several together (in this respect resem-
bling the Carranchas) wait at the mouth of a rabbit-hole,
and together seize on the animal when it comes out. They
were constantly flying on board the vessel when in the har-
bour ; and it was necessary to keep a good look out to prevent
the leather being torn from the rigging, and the meat or
game from the stern. These birds are very mischievous and
inquisitive; they will pick up almost anything from the
ground; a large black glazed hat was carried nearly a mile,
as was a pair of the heavy balls used in catching cattle. Mr.
Usborne experienced during the survey a more severe loss,
in their stealing a small Kater's compass in a red morocco
leather case, which was never recovered. These birds are,
moreover, quarrelsome and very passionate; tearing up the
grass with their bills from rage. They are not truly grega-

THE VOYAGE OF THE BEAGLE 69

rious ; they do not soar, and their flight is heavy and clumsy ;
on the ground they run extremely fast, very much like
pheasants. They are noisy, uttering several harsh cries, one
of which is like that of the English rook; hence the sealers
always call them rooks. It is a curious circumstance that,
when crying out, they throw their heads upwards and back-
wards, after the same manner as the Carrancha. They build
in the rocky cliffs of the sea-coast, but only on the small
adjoining islets, and not on the two main islands: this is a
singular precaution in so tame and fearless a bird. The seal-
ers say that the flesh of these birds, when cooked, is quite
white, and very good eating; but bold must the man be who
attempts such a meal.

We have now only to mention the turkey-buzzard (Vultur
aura), and the Gallinazo. The former is found wherever
the country is moderately damp, from Cape Horn to North
America. Differently from the Polyborus Brasiliensis and
Chimango, it has found its way to the Falkland Islands. The
turkey-buzzard is a solitary bird, or at most goes in pairs. It
may at once be recognised from a long distance, by its lofty,
soaring, and most elegant flight. It is well known to be a
true carrion-feeder. On the west coast of Patagonia, among
the thickly-wooded islets and broken land, it lives exclusively
on what the sea throws up, and on the carcasses of dead
seals. Wherever these animals are congregated on the rocks,
there the vultures may be seen. The Gallinazo (Cathartes
atratus) has a different range from the last species, as it
never occurs southward of lat. 41°. Azara states that there
exists a tradition that these birds, at the time of the conquest,
were not found near Monte Video, but that they subsequently
followed the inhabitants from more northern districts. At
the present day they are numerous in the valley of the Colo-
rado, which is three hundred miles due south of Monte
Video. It seems probable that this additional migration has
happened since the time of Azara. The Gallinazo generally
prefers a humid climate, or rather the neighbourhood of
fresh water; hence it is extremely abundant in Brazil and
La Plata, while it is never found on the desert and arid
plains of Northern Patagonia, excepting near some stream.
These birds frequent the whole Pampas to the foot of the

70 CHARLES DARWIN

Cordillera, but I never saw or heard of one in Chile ; in Peru
they are preserved as scavengers. These vultures certainly
may be called gregarious, for they seem to have pleasure in
society, and are not solely brought together by the attraction
of a common prey. On a fine day a flock may often be
observed at a great height, each bird wheeling round and
round without closing its wings, in the most graceful evolu-
tions. This is clearly performed for the mere pleasure of
the exercise, or perhaps is connected with their matrimonial
alliances.

I have now mentioned all the carrion-feeders, excepting
the condor, an account of which will be more appropriately
introduced when we visit a country more congenial to its
habits than the plains of La Plata.

In a broad band of sand-hillocks which separate the
Laguna del Potrero from the shores of the Plata, at the dis-
tance of a few miles from Maldonado, I found a group of
those vitrified, siliceous tubes, which are formed by lightning
entering loose sand. These tubes resemble in every particu-
lar those from Drigg in Cumberland, described in the
Geological Transactions.10 The sand-hillocks of Maldonado,
not being protected by vegetation, are constantly changing
their position. From this cause the tubes projected above
the surface, and numerous fragments lying near, showed
that they had formerly been buried to a greater depth. Four
sets entered the sand perpendicularly: by working with
my hands I traced one of them two feet deep; and some
fragments which evidently had belonged to the same tube,
when added to the other part, measured five feet three
inches. The diameter of the whole tube was nearly equal,
and therefore we must suppose that originally it extended to
a much greater depth. These dimensions are however small,
compared to those of the tubes from Drigg, one of which
was traced to a depth of not less than thirty feet.

The internal surface is completely vitrified, glossy, and
smooth. A small fragment examined under the microscope

"Geolog. Transact, vol. ii. p. 528. In the Philosoph. Transact (1700,
p. 294) Dr. Priestley has described some imperfect siliceous tubes and a
melted pebble of quartz, found in digging into the ground, under a tree,
where a man had been killed by lightning.

THE VOYAGE OF THE BEAGLE 71

appeared, from the number of minute entangled air or per-
haps steam bubbles, like an assay fused before the blowpipe.
The sand is entirely, or in greater part, siliceous; but some
points are of a black colour, and from their glossy surface
possess a metallic lustre. The thickness of the wall of the
tube varies from a thirtieth to a twentieth of an inch, and
occasionally even equals a tenth. On the outside the grains
of sand are rounded, and have a slightly glazed appearance:
I could not distinguish any signs of crystallization. In a
similar manner to that described in the Geological Transac-
tions, the tubes are generally compressed, and have deep
longitudinal furrows, so as closely to resemble a shrivelled
vegetable stalk, or the bark of the elm or cork tree. Their
circumference is about two inches, but in some fragments,
which are cylindrical and without any furrows, it is as much
as four inches. The compression from the surrounding loose
sand, acting while the tube was still softened from the effects
of the intense heat, has evidently caused the creases or fur-
rows. Judging from the uncompressed fragments, the meas-
ure or bore of the lightning (if such a term may be used)
must have been about one inch and a quarter. At Paris, M.
Hachette and M. Beudantu succeeded in making tubes, in
most respects similar to these fulgurites, by passing very
strong shocks of galvanism through finely-powdered glass:
when salt was added, so as to increase its fusibility, the tubes
were larger in every dimension. They failed both with
powdered felspar and quartz. One tube, formed with
pounded glass, was very nearly an inch long, namely .982,
and had an internal diameter of .019 of an inch. When we
hear that the strongest battery in Paris was used, and that
its power on a substance of such easy fusibility as glass was
to form tubes so diminutive, we must feel greatly astonished
at the force of a shock of lightning, which, striking the sand
in several places, has formed cylinders, in one instance of at
least thirty feet long, and having an internal bore, where not
compressed, of full an inch and a half; and this in a materiaJ
so extraordinarily refractory as quartz !

The tubes, as I have already remarked, enter the sand
nearly in a vertical direction. One, however, which was less

72 CHARLES DARWIN

regular than the others, deviated from a right line, at the
most considerable bend, to the amount of thirty-three de-
grees. From this same tube, two small branches, about a
foot apart, were sent off; one pointed downwards, and the
other upwards. This latter case is remarkable, as the elec-
tric fluid must have turned back at the acute angle of 26°,
to the line of its main course. Besides the four tubes which
I found vertical, and traced beneath the surface, there were
several other groups of fragments, the original sites of which
without doubt were near. All occurred in a level area of
shifting sand, sixty yards by twenty, situated among some
high sand-hillocks, and at the distance of about half a mile
from a chain of hills four or five hundred feet in height. The
most remarkable circumstance, as it appears to me, in this
case as well as in that of Drigg, and in one described by
M. Ribbentrop in Germany, is the number of tubes found
within such limited spaces. At Drigg, within an area of
fifteen yards, three were observed, and the same number
occurred in Germany. In the case which I have described,
certainly more than four existed within the space of the
sixty by twenty yards. As it does not appear probable that
the tubes are produced by successive distinct shocks, we must
believe that the lightning, shortly before entering the ground,
divides itself into separate branches.

The neighbourhood of the Rio Plata seems peculiarly sub-
ject to electric phenomena. In the year I793,12 one of the
most destructive thunderstorms perhaps on record happened
at Buenos Ayres: thirty-seven places within the city were
struck by lightning, and nineteen people killed. From facts
stated in several books of travels, I am inclined to suspect
that thunderstorms are very common near the mouths of
great rivers. Is it not possible that the mixture of large
bodies of fresh and salt water may disturb the electrical
equilibrium? Even during our occasional visits to this part
of South America, we heard of a ship, two churches, and a
house having been struck. Both the church and the house
I saw shortly afterwards: the house belonged to Mr. Hood,
the consul-general at Monte Video. Some of the effects were
curious : the paper, for nearly a foot on each side of the line

where the bell-wires had run, was blackened. The metal had
been fused, and although the room was about fifteen feet
high, the globules, dropping on the chairs and furniture, had
drilled in them a chain of minute holes. A part of the wall
was shattered, as if by gunpowder, and the fragments had
been blown off with force sufficient to dent the wall on the
opposite side of the room. The frame of a looking-glass was
blackened, and the gilding must have been volatilized, for a
smelling-bottle, which stood on the chimney-piece, was coated
with bright metallic particles, which adhered as firmly as
if they had been enamelled.

/ULY 24th, 1833. — The Beagle sailed from Maldonado,
and on August the 3rd she arrived off the mouth of the
Rio Negro. This is the principal river on the whole line
of coast between the Strait of Magellan and the Plata. It
enters the sea about three hundred miles south of the estuary
of the Plata. About fifty years ago, under the old Spanish
government, a small colony was established here ; and it is
still the most southern position (lat. 41°) on this eastern
coast of America inhabited by civilized man.

The country near the mouth of the river is wretched in
the extreme: on the south side a long line of perpendicular
cliffs commences, which exposes a section of the geological
nature of the country. The strata are of sandstone, and
one layer was remarkable from being composed of a firmly-
cemented conglomerate of pumice pebbles, which must have
travelled more than four hundred miles, from the Andes.
The surface is everywhere covered up by a thick bed of
gravel, which extends far and wide over the open plain.
Water is extremely scarce, and, where found, is almost in-
variably brackish. The vegetation is scanty; and although
there are bushes of many kinds, all are armed with formida-
ble thorns, which seem to warn the stranger not to enter on
these inhospitable regions.

The settlement is situated eighteen miles up the river.
The road follows the foot of the sloping cliff, which forms
the northern boundary of the great valley, in which the Rio
Negro flows. On the way we passed the ruins of some fine

THE VOYAGE OF THE BEAGLE 75

"estancias," which a few years since had been destroyed by
the Indians. They withstood several attacks. A man present
at one gave me a very lively description of what took place.
The inhabitants had sufficient notice to drive all the cattle
and horses into the " corral >n which surrounded the house,
and likewise to mount some small cannon. The Indians were
Araucanians from the south of Chile; several hundreds in
number, and highly disciplined. They first appeared in two
bodies on a neighbouring hill; having there dismounted, and
taken off their fur mantles, they advanced naked to the
charge. The only weapon of an Indian is a very long bam-
boo or chuzo, ornamented with ostrich feathers, and pointed
by a sharp spearhead. My informer seemed to remember
with the greatest horror the quivering of these chuzos as they
approached near. When close, the cacique Pincheira hailed
the besieged to give up their arms, or he would cut all their
throats. As this would probably have been the result of
their entrance under any circumstances, the answer was
given by a volley of musketry. The Indians, with great
steadiness, came to the very fence of the corral : but to their
surprise they found the posts fastened together by iron nails
instead of leather thongs, and, of course, in vain attempted
to cut them with their knives. This saved the lives of the
Christians : many of the wounded Indians were carried away
by their companions, and at last, one of the under caciques
being wounded, the bugle sounded a retreat. They retired to
their horses, and seemed to hold a council of war. This was
an awful pause for the Spaniards, as all their ammunition,
with the exception of a few cartridges, was expended. In
an instant the Indians mounted their horses, and galloped
out of sight. Another attack was still more quickly repulsed.
A cool Frenchman managed the gun; he stopped till the
Indians approached close, and then raked their line with
grape-shot: he thus laid thirty-nine of them on the ground;
and, of course, such a blow immediately routed the whole
party.

The town is indifferently called El Carmen or Patagones.
Tt is built on the face of a cliff which fronts the river, and

^The corral is an enclosure made of tall and strong stakes. Every
estancia, or farming estate, has one attached to it.

many of the houses are excavated even in the sandstone.
The river is about two or three hundred yards wide, and is
deep and rapid. The many islands, with their willow-trees,
and the flat headlands, seen one behind the other on the
northern boundary of the broad green valley, form, by the
aid of a bright sun, a view almost picturesque. The number
of inhabitants does not exceed a few hundreds. These Span-
ish colonies do not, like our British ones, carry within them-
selves the elements of growth. Many Indians of pure blood
reside here : the tribe of the Cacique Lucanee constantly have
their Toldos2 on the outskirts of the town. The local gov-
ernment partly supplies them with provisions, by giving them
all the old worn-out horses, and they earn a little by making
horse-rugs and other articles of riding-gear. These Indians
are considered civilized; but what their character may have
gained by a lesser degree of ferocity, is almost counterbal-
anced by their entire immorality. Some of the younger men
are, however, improving; they are willing to labour, and a
short time since a party went on a sealing-voyage, and be-
haved very well. They were now enjoying the fruits of their
labour, by being dressed in very gay, clean clothes, and by
being very idle. The taste they showed in their dress was
admirable; if you could have turned one of these young
Indians into a statue of bronze, his drapery would have been
perfectly graceful.

One day I rode to a large salt-lake, or Salina, which is
distant fifteen miles from the town. During the winter it
consists of a shallow lake of brine, which in summer is con-
verted into a field of snow-white salt. The layer near the
margin is from four to five inches thick, but towards the
centre its thickness increases. This lake was two and a half
miles long, and one broad. Others occur in the neighbour-
hood many times larger, and with a floor of salt, two and
three feet in thickness, even when under water during the
winter. One of these brilliantly white and level expanses,
in the midst of the brown and desolate plain, offers an
extraordinary spectacle. A large quantity of salt is annu-
ally drawn from the salina: and great piles, some hundred
tons in weight, were lying ready for exportation. The season

'The hovels of the Indians are thus called.

THE VOYAGE OF THE BEAGLE 77

for working the salinas forms the harvest of Patagones ; for
on it the prosperity of the place depends. Nearly the whole
population encamps on the bank of the river, and the people
are employed in drawing out the salt in bullock-waggons.
This salt is crystallized in great cubes, and is remarkably
pure: Mr. Trenham Reeks has kindly analyzed some for me,
and he finds in it only 0.26 of gypsum and 0.22 of earthy
matter. It is a singular fact, that it does not serve so well
for preserving meat as sea-salt from the Cape de Verd
islands; and a merchant at Buenos Ayres told me that he
considered it as fifty per cent, less valuable. Hence the
Cape de Verd salt is constantly imported, and is mixed with
that from these salinas. The purity of the Patagonian salt,
or absence from it of those other saline bodies found in all
sea-water, is the only assignable cause for this inferiority:
a conclusion which no one, I think, would have suspected,
but which is supported by the fact lately ascertained,3 that
those salts answer best for preserving cheese which contain
most of the deliquescent chlorides.

The border of this lake is formed of mud: and in this
numerous large crystals of gypsum, some of which are three
inches long, lie embedded; whilst on the surface others of
sulphate of soda lie scattered about. The Gauchos call the
former the " Padre del sal," and the latter the " Madre ; "
they state that these progenitive salts always occur on the
borders of the salinas, when the water begins to evaporate.
The mud is black, and has a fetid odour. I could not at first
imagine the cause of this, but I afterwards perceived that the
froth which the wind drifted on shore was coloured green,
as if by confervae; I attempted to carry home some of this
green matter, but from an accident failed. Parts of the lake
seen from a short distance appeared of a reddish colour, and
this perhaps was owing to some infusorial animalcula. The
mud in many places was thrown up by numbers of some kind
of worm, or annelidous animal. How surprising it is that
any creatures should be able to exist in brine, and that they
should be crawling among crystals of sulphate of soda and
lime ! And what becomes of these worms when, during the
long summer, the surface is hardened into a solid layer of

salt? Flamingoes in considerable numbers inhabit this lake,
and breed here; throughout Patagonia, in Northern Chile,
and at the Galapagos Islands, I met with these birds wher-
ever there were lakes of brine. I saw them here wading
about in search of food — probably for the worms which bur-
row in the mud ; and these latter probably feed on infusoria or
confervae. Thus we have a little living world within itself,
adapted to these inland lakes of brine. A minute crustaceous
animal (Cancer salinus) is said* to live in countless numbers
in the brine-pans at Lymington: but only in those in which
the fluid has attained, from evaporation, considerable
strength — namely, about a quarter of a pound of salt to a
pint of water. Well may we affirm that every part of the
world is habitable ! Whether lakes of brine, or those sub-
terranean ones hidden beneath volcanic mountains — warm
mineral springs — the wide expanse and depths of the ocean
— the upper regions of the atmosphere, and even the surface
of perpetual snow — all support organic beings.

To the northward of the Rio Negro, between it and the
inhabited country near Buenos Ayres, the Spaniards have
only one small settlement, recently .established at Bahia
Blanca. The distance in a straight line to Buenos Ayres is
very nearly five hundred British miles. The wandering
tribes of horse Indians, which have always occupied the
greater part of this country, having of late much harassed
the outlying estancias, the government at Buenos Ayres
equipped some time since an army under the command of
General Rosas for the purpose of exterminating them. The
troops were now encamped on the banks of the Colorado;
a river lying about eighty miles northward of the Rio Negro.
When General Rosas left Buenos Ayres he struck in a direct

* Linnacan Trans., vol. xi. p. 205. It is remarkable how all the circum-
stances connected with the salt-lakes in Siberia and Patagonia are similar.
Siberia, like Patagonia, appears to have been recently elevated above the
waters of the sea. In both countries the salt-lakes occupy shallow depres-
sions in the plains; in both the mud on the borders is black and fetid;
beneath the crust of common salt, sulphate of soda or of magnesia occurs,
imperfectly crystallized; and in both, the muddy sand is mixed with lentils
of gypsum. The Siberian salt-lakes are inhabited by small crustaceous ani-
mals; and flamingoes (Edin. New Philos. Jour., Jan. 1830) likewise frequent
them. As these circumstances, apparently so trifling, occur in two distant
continents, we may feel sure that they are the necessary results of common
', causes. — See Pallas' 's Travels, 1793 to 1794, pp. 129-134.

THE VOYAGE OF THE BEAGLE 79

line across the unexplored plains: and as the country was
thus pretty well cleared of Indians, he left behind him, at
wide intervals, a small party of soldiers with a troop of
horses (a post a), so as to be enabled to keep up a communi-
cation with the capital. As the Beagle intended to call at
Bahia Blanca, I determined to proceed there by land; and
ultimately I extended my plan to travel the whole way by
the postas to Buenos Ayres.

August nth. — Mr. Harris, an Englishman residing at
Patagones, a guide, and five Gauchos who were proceeding
to the army on business, were my companions on the jour-
ney. The Colorado, as I have already said, is nearly eighty
miles distant: and as we travelled slowly, we were two days
and a half on the road. The whole line of country deserves
scarcely a better name than that of a desert. Water is found
only in two small wells; it is called fresh; but even at this
time of the year, during the rainy season, it was quite brack-
ish. In the summer this must be a distressing passage; for
now it was sufficiently desolate. The valley of the Rio
Negro, broad as it is, has merely been excavated out of the
sandstone plain; for immediately above the bank on which
the town stands, a level country commences, which is inter-
rupted only by a few trifling valleys and depressions. Every-
where the landscape wears the same sterile aspect; a dry
gravelly soil supports tufts of brown withered grass, and
low scattered bushes, armed with thorns.

Shortly after passing the first spring we came in sight of
a famous tree, which the Indians reverence as the altar of
Walleechu. It is situated on a high part of the plain; and
hence is a landmark visible at a great distance. As soon as a
tribe of Indians come in sight of it, they offer their adora-
tions by loud shouts. The tree itself is low, much branched,
and thorny: just above the root it has a diameter of about
three feet. It stands by itself without any neighbour, and
was indeed the first tree we saw ; afterwards we met with a
few others of the same kind, but they were far from commoa
Being winter the tree had no leaves, but in their place num-
berless threads, by which the various offerings, such as
cigars, bread, meat, pieces of cloth, etc., had been suspended.
Poor Indians, not having anything better, only pull a thread

80 CHARLES DARWIN

out of their ponchos, and fasten it to the tree. Richer
Indians are accustomed to pour spirits and mate into a cer-
tain hole, and likewise to smoke upwards, thinking thus to
afford all possible gratification to Walleechu. To complete
the scene, the tree was surrounded by the bleached bones
of horses which had been slaughtered as sacrifices. All
Indians of every age and sex make their offerings ; they then
think that their horses will not tire, and that they themselves
shall be prosperous. The Gaucho who told me this, said that
in the time of peace he had witnessed this scene, and that
he and others used to wait till the Indians had passed by, for
the sake of stealing from Walleechu the offerings.

The Gauchos think that the Indians consider the tree as
the god itself, but it seems for more probable that they
regard it as the altar. The only cause which I can imagine
for this choice, is its being a landmark in a dangerous pas-
sage. The Sierra de la Ventana is visible at an immense
distance ; and a Gaucho told me that he was once riding with
an Indian a few miles to the north of the Rio Colorado,
when the Indian commenced making the same loud noise,
which is usual at the first sight of the distant tree; putting
his hand to his head, and then pointing in the direction of the
Sierra. Upon being asked the reason of this, the Indian said
in broken Spanish, " First see the Sierra." About two
leagues beyond this curious tree we halted for the night: at
this instant an unfortunate cow was spied by the lynx-eyed
Gauchos, who set off in full chase, and in a few minutes
dragged her in with their lazos, and slaughtered her. We
here had the four necessaries of life " en el campo," — pas-
ture for the horses, water (only a muddy puddle), meat and
firewood. The Gauchos were in high spirits at finding all
these luxuries ; and we soon set to work at the poor cow. This
was the first night which I passed under the open sky, with
the gear of the recado for my bed. There is high enjoyment
in the independence of the Gaucho life — to be able at any
moment to pull up your horse, and say, " Here we will pass
the night." The death-like stillness of the plain, the dogs
keeping watch, the gipsy-group of Gauchos making their
beds round the fire, have left in my mind a strongly-marked
picture of this first night, which will never be forgotten.

THE VOYAGE OF THE BEAGLE 81

The next day the country continued similar to that above
described. It is inhabited by few birds or animals of any
kind. Occasionally a deer, or a Guanaco (wild Llama) may
be seen; but the Agouti (Cavia Patagonica) is the common-
est quadruped. This animal here represents our hares. It
differs, however, from that genus in many essential respects ;
for instance, it has only three toes behind. It is also nearly
twice the size, weighing from twenty to twenty-five pounds.
The Agouti is a true friend of the desert; it is a common
feature of the landscape to see two or three hopping quickly
one after the other in a straight line across these wild plains.
They are found as far north as the Sierra Tapalguen (lat.
37° 30'), where the plain rather suddenly becomes greener
and more humid; and their southern limit is between Port
Desire and St. Julian, where there is no change in the nature
of the country. It is a singular fact, that although the
Agouti is not now found as far south as Port St. Julian, yet
that Captain Wood, in his voyage in 1670, talks of them as
being numerous there. What cause can have altered, in a
wide, uninhabited, and rarely-visited country, the range of
an animal like this? It appears also, from the number shot
by Captain Wood in one day at Port Desire, that they must
have been considerably more abundant there formerly than
at present. Where the Bizcacha lives and makes its burrows,
the Agouti uses them; but where, as at Bahia Blanca, the
Bizcacha is not found, the Agouti burrows for itself. The
same thing occurs with the little owl of the Pampas (Athene
cunicularia), which has so often been described as standing
like a sentinel at the mouth of the burrows; for in Banda
Oriental, owing to the absence of the Bizcacha, it is obliged
to hollow out its own habitation.

The next morning, as we approached the Rio Colorado,
the appearance of the country changed; we soon came on a
plain covered with turf, which, from its flowers, tall clover,
and little owls, resembled the Pampas. We passed also a
muddy swamp of considerable extent, which in summer dries,
and becomes incrusttd with various salts ; and hence is called
a salitral. It was covered by low succulent plants, of the
same kind with those growing on the sea-shore. The Colo-
rado, at the pass where we crossed it, is only about sixty

83 CHARLES DARWIN

yards wide; generally it must be nearly double that width.
Its course is very tortuous, being marked by willow-trees
and beds of reeds: in a direct line the distance to the mouth
of the river is said to be nine leagues, but by water twenty-
five. We were delayed crossing in the canoe by some im-
mense troops of mares, which were swimming the river in
order to follow a division of troops into the interior. A
more ludicrous spectacle I never beheld than the hundreds
and hundreds of heads, all directed one way, with pointed
ears and distended snorting nostrils, appearing just above
the water like a great shoal of some amphibious animal.
Mare's flesh is the only food which the soldiers have when
on an expedition. This gives them a great facility of move-
ment; for the distance to which horses can be driven over
these plains is quite surprising: I have been assured that an
unloaded horse can travel a hundred miles a day for many
days successively.

The encampment of General Rosas was close to the river.
It consisted of a square formed by waggons, artillery, straw
huts, etc. The soldiers were nearly all cavalry ; and I should
think such a villainous, banditti-like army was never before
collected together. The greater number of men were of a
mixed breed, between Negro, Indian, and Spaniard. I know
not the reason, but men of such origin seldom have a good
expression of countenance. I called on the Secretary to show
my passport. He began to cross-question me in the most
dignified and mysterious manner. By good luck I had a
letter of recommendation from the government of Buenos
Ayres* to the commandant of Patagones. This was taken
to General Rosas, who sent me a very obliging message ; and
the Secretary returned all smiles and graciousness. We took
up our residence in the rancho, or hovel, of a curious old
Spaniard, who had served with Napoleon in the expedition
against Russia.

We stayed two days at the Colorado; I had little to do,
for the surrounding country was a swamp, which in summer
(December), when the snow melts on the Cordillera, is over-
flowed by the river. My chief amusement was watching the

6 1 am hound to express, in the strongest terms, my obligation to the
government of Buenos Ayres for the obliging manner in which passports
to all parts of the country were given me, as naturalist of the Beagle.

THE VOYAGE OF THE BEAGLE 83

Indian families as they came to buy little articles at the
rancho where we stayed. It was supposed that General
Rosas had about six hundred Indian allies. The men were
a tall, fine race, yet it was afterwards easy to see in the
Fuegian savage the same countenance rendered hideous by
cold, want of food, and less civilization. Some authors,
in defining the primary races of mankind, have separated
these Indians into two classes; but this is certainly incor-
rect. Among the young women or chinas, some deserve to
be called even beautiful. Their hair was coarse, but bright
and black; and they wore it in two plaits hanging down
to the waist. They had a high colour, and eyes that
glistened with brilliancy; their legs, feet, and arms were
small and elegantly formed; their ankles, and sometimes
their wrists, were ornamented by broad bracelets of blue
beads. Nothing could be more interesting than some of the
family groups. A mother with one or two daughters would
often come to our rancho, mounted on the same horse. They
ride like men, but with their knees tucked up much higher.
This habit, perhaps, arises from their being accustomed,
when travelling, to ride the loaded horses. The duty of the
women is to load and unload the horses; to make the tents
for the night; in short to be, like the wives of all savages,
useful slaves. The men fight, hunt, take care of the horses,
and make the riding gear. One of their chief indoor occupa-
tions is to knock two stones together till they become round,
in order to make the bolas. With this important weapon the
Indian catches his game, and also his horse, which roams
free over the plain. In fighting, his first attempt is to throw
down the horse of his adversary with the bolas, and when
entangled by the fall to kill him with the chuzo. If the balls
only catch the neck or body of an animal, they are often
carried away and lost. As the making the stones round is
the labour of two days, the manufacture of the balls is a
very common employment. Several of the men and women
had their faces painted red, but I never saw the horizontal
bands which are so common among the Fuegians. Their
chief pride consists in having everything made of silver; I
have seen a cacique with his spurs, stirrups, handle of his
knife, and bridle made of this metal: the head-stall and reins

84 CHARLES DARWIN

being of wire, were not thicker than whipcord ; and to see a
fiery steed wheeling about under the command of so light
a chain, gave to the horsemanship a remarkable character of
elegance.

General Rosas intimated a wish to see me; a circumstance
which I was afterwards very glad of. He is a man of an
extraordinary character, and has a most predominant influ-
ence in the country, which it seems he will use to its pros-
perity and advancement.* He is said to be the owner of
seventy-four square leagues of land, and to have about three
hundred thousand head of cattle. His estates are admirably
managed, and are far more productive of corn than those of
others. He first gained his celebrity by his laws for his own
estancias, and by disciplining several hundred men, so as to
resist with success the attacks of the Indians. There are
many stories current about the rigid manner in which his
laws were enforced. One of these was, that no man, on
penalty of being put into the stocks, should carry his knife
on a Sunday: this being the principal day for gambling and
drinking, many quarrels arose, which from the general man-
ner of fighting with the knife often proved fatal. One
Sunday the Governor came in great form to pay the estancia
a visit, and General Rosas, in his hurry, walked out to receive
him with his knife, as usual, stuck in his belt. The steward
touched his arm, and reminded him of the law ; upon which,
turning to the Governor, he said he was extremely sorry, but
that he must go into the stocks, and that till let out, he pos-
sessed no power even in his own house. After a little time
the steward was persuaded to open the stocks, and to let
him out, but no sooner was this done, than he turned to the
steward and said, " You now have broken the laws, so you
must take my place in the stocks." Such actions as these
delighted the Gauchos, who all possess high notions of their
own equality and dignity.

General Rosas is also a perfect horseman — an accomplish-
ment of no small consequence in a country where an assem-
bled army elected its general by the folowing trial: A troop
of unbroken horses being driven into a corral, were let out
through a gateway, above which was a cross-bar: it was

• This prophecy has turned out entirely and miserably wrong. .1845.

THE VOYAGE OF THE BEAGLE 85

agreed whoever should drop from the bar on one of these
wild animals, as it rushed out, and should be able, without
saddle or bridle, not only to ride it, but also to bring it back
to the door of the corral, should be their general. The per-
son who succeeded was accordingly elected ; and doubtless
made a fit general for such an army. This extraordinary
feat has also been performed by Rosas.

By these means, and by conforming to the dress and habits
of the Gauchos, he has obtained an unbounded popularity in
the country, and in consequence a despotic power. I was
assured by an English merchant, that a man who had mur-
dered another, when arrested and questioned concerning his
motive, answered, " He spoke disrespectfully of General
Rosas, so I killed him." At the end of a week the murderer
was at liberty. This doubtless was the act of the general's
party, and not of the general himself.

In conversation he is enthusiastic, sensible, and very
grave. His gravity is carried to a high pitch: I heard one
of his mad buffoons (for he keeps two, like the barons of
old) relate the following anecdote. " I wanted very much to
hear a certain piece of music, so I went to the general two
or three times to ask him ; he said to me, ' Go about your
business, for I am engaged.' I went a second time; he said,
'If you come again I will punish you.' A third time I
asked, and he laughed. I rushed out of the tent, but it was
too late; he ordered two soldiers to catch and stake me. I
begged by all the saints in heaven he would let me off ; but it
would not do; — when the general laughs he spares neither
mad man nor sound." The poor flighty gentleman looked quite
dolorous, at the very recollection of the staking. This is a
very severe punishment; four posts are driven into the
ground, and the man is extended by his arms and legs hori-
zontally, and there left to stretch for several hours. The
idea is evidently taken from the usual method of drying
hides. My interview passed away, without a smile, and I
obtained a passport and order for the government post-
horses, and this he gave me in the most obliging and ready
manner.

In the morning we started for Bahia Blanca, which we
reached in two days. Leaving the regular encampment, we

86 CHARLES DARWIN

passed by the toldos of the Indians. These are round like
ovens, and covered with hides ; by the mouth of each, a taper-
ing chuzo was stuck in the ground. The toldos were divided
into separate groups, which belong to the different caciques'
tribes, and the groups were again divided into smaller ones,
according to the relationship of the owners. For several
miles we travelled along the valley of the Colorado. The
alluvial plains on the side appeared fertile, and it is supposed
that they are well adapted to the growth of corn. Turning
northward from the river, we soon entered on a country, dif-
fering from the plains south of the river. The land still con-
tinued dry and sterile : but it supported many different kinds
of plants, and the grass, though brown and withered, was
more abundant, as the thorny bushes were less so. These
latter in a short space entirely disappeared, and the plains
were left without a thicket to cover their nakedness. This
change in the vegetation marks the commencement of the
grand calcareo argillaceous deposit, which forms the wide
extent of the Pampas, and covers the granitic rocks of Banda
Oriental. From the Strait of Magellan to the Colorado, a
distance of about eight hundred miles, the face of the coun-
try is everywhere composed of shingle: the pebbles are
chiefly of porphyry, and probably owe their origin to the
rocks of the Cordillera. North of the Colorado this bed
thins out, and the pebbles become exceedingly small, and
here the characteristic vegetation of Patagonia ceases.

Having ridden about twenty-five miles, we came to a
broad belt of sand-dunes, which stretches, as far as the eye
can reach, to the east and west. The sand-hillocks resting
on the clay, allow small pools of water to collect, and thus
afford in this dry country an invaluable supply of fresh
water. The great advantage arising from depressions and
elevations of the soil, is not often brought home to the mind.
The two miserable springs in the long passage between the
Rio Negro and Colorado were caused by trifling inequalities
in the plain; without them not a drop of water would have
been found. The belt of sand-dunes is about eight miles
wide; at some former period, it probably formed the margin
of a grand estuary, where the Colorado now flows. In this
district, where absolute proofs of the recent elevation of

THE VOYAGE OF THE BEAGLE 87

the land occur, such speculations can hardly be neglected by
any one, although merely considering the physical geography
of the country. Having crossed the sandy tract, we arrived
in the evening at one of the post-houses; and, as the fresh
horses were grazing at a distance we determined to pass
the night there.

The house was situated at the base of a ridge between
one and two hundred feet high — a most remarkable feature
in this country. This posta was commanded by a negro
lieutenant, born in Africa : to his credit be it said, there was
not a ranche between the Colorado and Buenos Ayres in
nearly such neat order as his. He had a little room for
strangers, and a small corral for the horses, all made of
sticks and reeds; he had also dug a ditch round his house
as a defence in case of being attacked. This would, how-
ever, have been of little avail, if the Indians had come ; but
his chief comfort seemed to rest in the thought of selling
his life dearly. A short time before, a body of Indians had
travelled past in the night; if they had been aware of the
posta, our black friend and his four soldiers would assuredly
have been slaughtered. I did not anywhere meet a more
civil and obliging man than this negro; it was therefore
the more painful to see that he would not sit down and eat
with us.

In the morning we sent for the horses very early, and
started for another exhilarating gallop. We passed the
Cabeza del Buey, an old name given to the head of a large
marsh, which extends from Bahia Blanca. Here we changed
horses, and passed through some leagues of swamps and
saline marshes. Changing horses for the last time, we again
began wading through the mud. My animal fell and I was
well soused in black mire — a very disagreeable accident
when one does not possess a change of clothes. Some miles
from the fort we met a man, who told us that a great gun
had been fired, which is a signal that Indians are near. We
immediately left the road, and followed the edge of a marsh,
which when chased offers the best mode of escape. We
were glad to arrive within the walls, when we found all the
alarm was about nothing, for the Indians turned out to be
friendly ones, who wished to join General Rosas.

Bahia Blanca scarcely deserves the name of a village. A
few houses and the barracks for the troops are enclosed by
a deep ditch and fortified wall. The settlement is only of
recent standing (since 1828) ; and its growth has been one of
trouble. The government of Buenos Ayres unjustly occu-
pied it by force, instead of following the wise example of the
Spanish Viceroys, who purchased the land near the older
settlement of the Rio Negro, from the Indians. Hence the
need of the fortifications; hence the few houses and little
cultivated land without the limits of the walls; even the
cattle are not safe from the attacks of the Indians beyond
the boundaries of the plain, on which the fortress stands.

The part of the harbour where the Beagle intended to
anchor being distant twenty-five miles, I obtained from the
Commandant a guide and horses, to take me to see whether
she had arrived. Leaving the plain of green turf, which
extended along the course of a little brook, we soon entered
on a wide level waste consisting either of sand, saline
marshes, or bare mud. Some parts were clothed by low
thickets, and others with those succulent plants, which lux-
uriate only where salt abounds. Bad as the country was,
ostriches, deer, agoutis, and armadilloes, were abundant. My
guide told me, that two months before he had a most narrow
escape of his life: he was out hunting with two other men,
at no great distance from this part of the country, when they
were suddenly met by a party of Indians, who giving chase,
soon overtook and killed his two friends. His own horse's
legs were also caught by the bolas; but he jumped off, and
with his knife cut them free: while doing this he was obliged
to dodge round his horse, and received two severe wounds
from their chuzos. Springing on the saddle, he managed, by
a most wonderful exertion, just to keep ahead of the long
spears of his pursuers, who followed him to within sight of
the fort. From that time there was an order that no one
should stray far from the settlement. I did not know of this
when I started, and was surprised to observe how earnestly
my guide watched a deer, which appeared to have been
frightened from a distant quarter.

We found the Beagle had not arrived, and consequently
set out on our return, but the horses soon tiring, we were

THE VOYAGE OF THE BEAGLE 80

obliged to bivouac on the plain. In the morning we had
caught an armadillo, which, although a most excellent dish
when roasted in its shell, did not make a very substantial
breakfast and dinner for two hungry men. The ground at
the place where we stopped for the night, was incrusted with
a layer of sulphate of soda, and hence, of course, was with-
out water. Yet many of the smaller rodents managed to
exist even here, and the tucutuco was making its odd little
grunt beneath my head, during half the night. Our horses
were very poor ones, and in the morning they were soon
exhausted from not having had anything to drink, so that
we were obliged to walk. About noon the dogs killed a kid,
which we roasted. I ate some of it, but it made me intoler-
ably thirsty. This was the more distressing as the road,
from some recent rain, was full of little puddles of clear
water, yet not a drop was drinkable. I had scarcely been
twenty hours without water, and only part of the time under
a hot sun, yet the thirst rendered me very weak. How people
survive two or three days under such circumstances, I cannot
imagine : at the same time, I must confess that my guide did
not suffer at all, and was astonished that one day's depriva-
tion should be so troublesome to me.

I have several times alluded to the surface of the ground
being incrusted with salt. This phenomenon is quite differ-
ent from that of the salinas, and more extraordinary. In
many parts of South America, wherever the climate is mod-
erately dry, these incrustations occur; but I have nowhere
seen them so abundant as near Bahia Blanca. The salt here,
and in other parts of Patagonia, consists chiefly of sulphate
of soda with some common salt. As long as the ground
remains moist in the salitrales (as the Spaniards improperly
call them, mistaking this substance for saltpetre), nothing is
to be seen but an extensive plain composed of a black, muddy
soil, supporting scattered tufts of succulent plants. On return-
ing through one of these tracts, after a week's hot weather,
one is surprised to see square miles of the plain white, as if
from a slight fall of snow, here and there heaped up by the
wind into little drifts. This latter appearance is chiefly
caused by the salts being drawn up, during the slow evapora-
tion of the moisture, round blades of dead grass, stumps of

90 CHARLES DARWIN

wood, and pieces of broken earth, instead of being crystal-
lized at the bottoms of the puddles of water. The salitrales
occur either on level tracts elevated only a few feet above
the level of the sea, or on alluvial land bordering rivers.
M. Parchappe7 found that the saline incrustation on the plain,
at the distance of some miles from the sea, consisted chiefly
of sulphate of soda, with only seven per cent, of common
salt; whilst nearer to the coast, the common salt increased
to 37 parts in a hundred. This circumstance would tempt
one to believe that the sulphate of soda is generated in the
soil, from the muriate, left on the surface during the slow
and recent elevation of this dry country. The whole phe-
nomenon is well worthy the attention of naturalists. Have
the succulent, salt-loving plants, which are well known to
contain much soda, the power of decomposing the muriate?
Does the black fetid mud, abounding with organic matter,
yield the sulphur and ultimately the sulphuric acid?

Two days afterwards I again rode to the harbour: when
not far from our destination, my companion, the same man
as before, spied three people hunting on horseback. He im-
mediately dismounted, and watching them intently, said,
" They don't ride like Christians, and nobody can leave the
fort." The three hunters joined company, and likewise dis-
mounted from their horses. At last one mounted again
and rode over the hill out of sight. My companion said,
" We must now get on our horses : load your pistol ;" and he
looked to his own sword. I asked, " Are they Indians ? " —
" Quien sabe? (who knows?) if there are no more than three,
it does not signify." It then struck me, that the one man
had gone over the hill to fetch the rest of his tribe. I sug-
gested this ; but all the answer I could extort was, " Quien
sabe ? " His head and eye never for a minute ceased scan-
ning slowly the distant horizon. I thought his uncommon
coolness too good a joke, and asked him why he did not
return home. I was startled when he answered, " We are
returning, but in a line so as to pass near a swamp, into
which we can gallop the horses as far as they can go, and
then trust to our own legs ; so that there is no danger." I did

torn. i. p. 664.

THE VOYAGE OP THE BEAGLE 91

not feel quite so confident of this, and wanted to increase
our pace. He said, " No, not until they do." When any
little inequality concealed us, we galloped ; but when in sight,
continued walking. At last we reached a valley, and turning
to the left, galloped quickly to the foot of a hill; he gave me
his horse to hold, made the dogs lie down, and then crawled
on his hands and knees to reconnoitre. He remained in this
position for some time, and at last, bursting out in laughter,
exclaimed, "Mugeres!" (women!). He knew them to be
the wife and sister-in-law of the major's son, hunting for
ostrich's eggs. I have described this man's conduct, because
he acted under the full impression that they were Indians.
As soon, however, as the absurd mistake was found out, he
gave me a hundred reasons why they could not have been
Indians; but all these were forgotten at the time. We then
rode on in peace and quietness to a low point called Punta
Alta, whence we could see nearly the whole of the great har-
bour of Bahia Blanca.

The wide expanse of water is choked up by numerous
great mud-banks, which the inhabitants call Cangrejales, or
crabberies, from the number of small crabs. The mud is so
soft that it is impossible to walk over them, even for the
shortest distance. Many of the banks have their surfaces
covered with long rushes, the tops of which alone are visible
at high water. On one occasion, when in a boat, we were
so entangled by these shallows that we could hardly find
our way. Nothing was visible but the flat beds of mud ; the
day was not very clear, and there was much refraction, or
as the sailors expressed it, " things loomed high." The only
object within our view which was not level was the horizon;
rushes looked like bushes unsupported in the air, and water
like mud-banks, and mud-banks like water.

We passed the night in Punta Alta, and I employed my-
self in searching for fossil bones ; this point being a perfect
catacomb for monsters of extinct races. The evening was
perfectly calm and clear; the extreme monotony of the view
gave it an interest even in the midst of mud-banks and gulls,
sand-hillocks and solitary vultures. In riding back in the
morning we came across a very fresh track of a Puma, but
did not succeed in finding it We saw also a couple of

92 CHARLES DARWIN

Zorillos, or skunks, — odious animals, which are far from un-
common. In general appearance, the Zorillo resembles a
polecat, but it is rather larger, and much thicker in propor-
tion. Conscious of its power, it roams by day about the open
plain, and fears neither dog nor man. If a dog is urged to
the attack, its courage is instantly checked by a few drops
of the fetid oil, which brings on violent sickness and run-
ning at the nose. Whatever is once polluted by it, is for
ever useless. Azara says the smell can be perceived at a
league distant; more than once, when entering the harbour
of Monte Video, the wind being off shore, we have per-
ceived the odour on board the Beagle. Certain it is, that
every animal most willingly makes room for the Zorillo.

THE Beagle arrived here on the 24th of August, and a
week afterwards sailed for the Plata. With Captain
Fitz Roy's consent I was left behind, to travel by land
to Buenos Ayres. I will here add some observations, which
were made during this visit and on a previous occasion, when
the Beagle was employed in surveying the harbour.

The plain, at the distance of a few miles from the coast,
belongs to the great Pampean formation, which consists in
part of a reddish clay, and in part of a highly calcareous
marly rock. Nearer the coast there are some plains formed
from the wreck of the upper plain, and from mud, gravel,
and sand thrown up by the sea during the slow elevation of
the land, of which elevation we have evidence in upraised
beds of recent shells, and in rounded pebbles of pumice scat-
tered over the country. At Punta Alta we have a section of
one of these later-formed little plains, which is highly inter-
esting from the number and extraordinary character of the
remains of gigantic land-animals embedded in it. These have
been fully described by Professor Owen, in the Zoology of the
voyage of the Beagle, and are deposited in the College of Sur-
geons. I will here give only a brief outline of their nature.

First, parts of three heads and other bones of the Mega-
therium, the huge dimensions of which are expressed by its
name. Secondly, the Megalonyx, a great allied animal.
Thirdly, the Scelidotherium, also an allied animal, of which
I obtained a nearly perfect skeleton. It must have been as

large as a rhinoceros : in the structure of its head it comes,
according to Mr. Owen, nearest to the Cape Anteater, but
in some other respects it approaches to the armadilloes.
Fourthly, the Mylodon Darwinii, a closely related genus of
little inferior size. Fifthly, another gigantic edental quadru-
ped. Sixthly, a large animal, with an osseous coat in com-
partments, very like that of an armadillo. Seventhly, an
extinct kind of horse, to which I shall have again to refer.
Eighthly, a tooth of a Pachydermatous animal, probably the
same with the Macrauchenia, a huge beast with a long neck
like a camel, which I shall also refer to again. Lastly, the
Toxodon, perhaps one of the strangest animals ever dis-
covered: in size it equalled an elephant or megatherium, but
the structure of its teeth, as Mr. Owen states, proves in-
disputably that it was intimately related to the Gnawers, the
order which, at the present day, includes most of the smallest
quadrupeds : in many details it is allied to the Pachyder-
mata: judging from the position of its eyes, ears, and nos-
trils, it was probably aquatic, like the Dugong and Manatee,
to which it is also allied. How wonderfully are the different
Orders, at the present time so well separated, blended to-
gether in different points of the structure of the Toxodon !
The remains of these nine great quadrupeds, and many
detached bones, were found embedded on the beach, within
the space of about 200 yards square. It is a remarkable cir-
cumstance that so many different species should be found
together; and it proves how numerous in kind the ancient
inhabitants of this country must have been. At the distance
of about thirty miles from Punta Alta, in a cliff of red earth,
I found several fragments of bones, some of large size.
Among them were the teeth of a gnawer, equalling in size
and closely resembling those of the Capybara, whose habits
have been described; and therefore, probably, an aquatic
animal. There was also part of the head of a Ctenomys ; the
species being different from the Tucutuco, but with a close
general resemblance. The red earth, like that of the Pampas,
in which these remains were embedded, contains, according
to Professor Ehrenberg, eight fresh-water and one salt-water
infusorial animalcule; therefore, probably, it was an estuary
deposit.

THE VOYAGE OF THE BEAGLE 95

The remains at Punta Alta were embedded in stratified
gravel and reddish mud, just such as the sea might now wash
up on a shallow bank. They were associated with twenty-
three species of shells, of which thirteen are recent and four
others very closely related to recent forms.1 From the bones
of the Scelidotherium, including even the knee-cap, being
intombed in their proper relative positions, and from the
osseous armour of the great armadillo-like animal being so
well preserved, together with the bones of one of its legs, we
may feel assured that these remains were fresh and united by
their ligaments, when deposited in the gravel together with
the shells.3 Hence we have good evidence that the above
enumerated gigantic quadrupeds, more different from those
of the present day than the oldest of the tertiary quadru-
peds of Europe, lived whilst the sea was peopled with most
of its present inhabitants; and we have confirmed that re-
markable law so often insisted on by Mr. Lyell, namely, that
the " longevity of the species in the mammalia is upon the
whole inferior to that of the testacea."3

The great size of the bones of the Megatheroid animals,
including the Megatherium, Megalonyx, Scelidotherium, and
Mylodon, is truly wonderful. The habits of life of these
animals were a complete puzzle to naturalists, until Professor
Owen* solved the problem with remarkable ingenuity. The
teeth indicate, by their simple structure, that these Mega-
theroid animals lived on vegetable food, and probably on the
leaves and small twigs of trees ; their ponderous forms and
great strong curved claws seem so little adapted for locomo-
tion, that some eminent naturalists have actually believed,
that, like the sloths, to which they are intimately related,
they subsisted by climbing back downwards on trees, and
feeding on the leaves. It was a bold, not to say preposterous,

1 Since this was written, M. Alcide d'Orbigny has examined these shells,
and pronounces them all to be recent.

* M. Aug. Bravard has described, in a Spanish work (' Observaciones
Geologicas, 1857), this district, and he believes that the bones of thf
extinct mammals were washed out of the underlying Pampean deposit,
and subsequently became embedded with the still existing shells; but I
am not convinced by his remarks. M. Bravard believes that the whole
enormous Pampean deposit is a sub-aerial formation, like sand-dunes:
this seems to me to be an untenable doctrine.

3 Principles of Geology, vol. iv. p. 40.

*This theory was first developed in the Zoology of the Voyage of the
Beagle, and subsequently in Professor Owen's Memoir on Mylodon robustus.

96 CHARLES DARWIN

idea to conceive even antediluvian trees, with branches
strong enough to bear animals as large as elephants. Profes-
sor Owen, with far more probability, believes that, instead
of climbing on the trees, they pulled the branches down to
them, and tore up the smaller ones by the roots, and so fed on
the leaves. The colossal breadth and weight of their hinder
quarters, which can hardly be imagined without having been
seen, become, on this view, of obvious service, instead of
being an incumbrance : their apparent clumsiness disappears.
With their great tails and their huge heels firmly fixed like
a tripod on the ground, they could freely exert the full force
of their most powerful arms and great claws. Strongly
rooted, indeed, must that tree have been, which could have
resisted such force ! The Mylodon, moreover, was furnished
with a long extensile tongue like that of the giraffe, which,
by one of those beautiful provisions of nature, thus reaches
with the aid of its long neck its leafy food. I may remark,
that in Abyssinia the elephant, according to Bruce, when it
cannot reach with its proboscis the branches, deeply scores
with its tusks the trunk of the tree, up and down and all
round, till it is sufficiently weakened to be broken down.

The beds including the above fossil remains, stand only
from fifteen to twenty feet above the level of high-water;
and hence the elevation of the land has been small (without
there has been an intercalated period of subsidence, of which
we have no evidence) since the great quadrupeds wandered
over the surrounding plains; and the external features of
the country must then have been very nearly the same as
now. What, it may naturally be asked, was the character
of the vegetation at that period ; was the country as wretch-
edly sterile as it now is? As so many of the co-embedded
shells are the same with those now living in the bay, I was
at first inclined to think that the former vegetation was
probably similar to the existing one; but this would have
been an erroneous inference, for some of these same shells
live on the luxuriant coast of Brazil; and generally, the
character of the inhabitants of the sea are useless as guides
to judge of those on the land. Nevertheless, from the fol-
lowing considerations, I do not believe that the simple fact
of many gigantic quadrupeds having lived on the plains

THE VOYAGE OF THE BEAGLE 97

round Bahia Blanca, is any sure guide that they formerly
were clothed with a luxuriant vegetation : I have no doubt
that the sterile country a little southward, near the Rio
Negro, with its scattered thorny trees, would support many
and large quadrupeds.

That large animals require a luxuriant vegetation, has
been a general assumption which has passed from one work
to another; but I do not hesitate to say that it is completely
false, and that it has vitiated the reasoning of geologists
on some points of great interest in the ancient history of
the world. The prejudice has probably been derived from
India, and the Indian islands, where troops of elephants,
noble forests, and impenetrable jungles, are associated to-
gether in every one's mind. If, however, we refer to any
work of travels through the southern parts of Africa, we
shall find allusions in almost every page either to the desert
character of the country, or to the numbers of large ani-
mals inhabiting it. The same thing is rendered evident
by the many engravings which have been published of vari-
ous parts of the interior. When the Beagle was at Cape
Town, I made an excursion of some days' length into the
country, which at least was sufficient to render that which
I had read more fully intelligible.

Dr. Andrew Smith, who, at the head of his adventurous
party, has lately succeeded in passing the Tropic of Capri-
corn, informs me that, taking into consideration the whole
of the southern part of Africa, there can be no doubt of its
being a sterile country. On the southern and south-eastern
coasts there are some fine forests, but with these exceptions,
the traveller may pass for days together through open plains,
covered by a poor and scanty vegetation. It is difficult to
convey any accurate idea of degrees of comparative fertil-
ity; but it may be safely said that the amount of vegetation
supported at any one time5 by Great Britain, exceeds, per-
haps even tenfold, the quantity on an equal area, in the
interior parts of Southern Africa. The fact that bullock-
waggons can travel in any direction, excepting near the

6 1 mean by this to exclude the total amount which may have been
successively produced and consumed during a given period.

VOL. XXIX — D HC

98 CHARLES DARWIN

coast, without more than occasionally half an hour's delay
in cutting down bushes, gives, perhaps, a more definite notion
of the scantiness of the vegetation. Now, if we look to the
animals inhabiting these wide plains, we shall find their
numbers extraordinarily great, and their bulk immense. We
must enumerate the elephant, three species of rhinoceros,
and probably, according to Dr. Smith, two others, the hippo-
potamus, the giraffe, the bos caffer — as large as a full-grown
bull, and the elan — but little less, two zebras, and the quac-
cha, two gnus, and several antelopes even larger than these
latter animals. It may be supposed that although the spe-
cies are numerous, the individuals of each kind are few.
By the kindness of Dr. Smith, I am enabled to show that
the case is very different. He informs me, that in lat. 24°,
in one day's march with the bullock-waggons, he saw, with-
out wandering to any great distance on either side, between
one hundred and one hundred and fifty rhinoceroses, which
belonged to three species : the same day he saw several herds
of giraffes, amounting together to nearly a hundred; and
that although no elephant was observed, yet they are found
in this district. At the distance of a little more than one
hour's march from their place of encampment on the pre-
vious night, his party actually killed at one spot eight hippo-
potamuses, and saw many more. In this same river there
were likewise crocodiles. Of course it was a case quite ex-
traordinary, to see so many great animals crowded together,
but it evidently proves that they must exist in great num-
bers. Dr. Smith describes the country passed through that
day, as " being thinly covered with grass, and bushes about
four feet high, and still more thinly with mimosa-trees."
The waggons were not prevented travelling in a nearly
straight line.

Besides these large animals, every one the least ac-
quainted with the natural history of the Cape, has read of
the herds of antelopes, which can be compared only with the
flocks of migratory birds. The numbers indeed of the lion,
panther, and hyaena, and the multitude of birds of prey,
plainly speak of the abundance of the smaller quadrupeds:
one evening seven lions were counted at the same time prowl-
ing round Dr. Smith's encampment. As this able naturalist

THE VOYAGE OF THE BEAGLE 99

remarked to me, the carnage each day in Southern Africa
must indeed be terrific ! I confess it is truly surprising how
such a number of animals can find support in a country
producing so little food. The larger quadrupeds no doubt
roam over wide tracts in search of it ; and their food chiefly
consists of underwood, which probably contains much nutri-
ment in a small bulk. Dr. Smith also informs me that the
vegetation has a rapid growth ; no sooner is a part consumed,
than its place is supplied by a fresh stock. There can be
no doubt, however, that our ideas respecting the apparent
amount of food necessary for the support of large quadru-
peds are much exaggerated : it should have been remembered
that the camel, an animal of no mean bulk, has always been
considered as the emblem of the desert.

The belief that where large quadrupeds exist, the vegeta-
tion must necessarily be luxuriant, is the more remarkable,
because the converse is far from true. Mr. Burchell observed
to me that when entering Brazil, nothing struck him more
forcibly than the splendour of the South American vegeta-
tion contrasted with that of South Africa, together with
the absence of all large quadrupeds. In his Travels,* he has
suggested that the comparison of the respective weights (if
there were sufficient data) of an equal number of the largest
herbivorous quadrupeds of each country would be extremely
curious. If we take on the one side, the elephant,7 hippo-
potamus, giraffe, bos caffer, elan, certainly three, and prob-
ably five species of rhinoceros; and on the American side,
two tapirs, the guanaco, three deer, the vicuna, peccari, capy-
bara (after which we must choose from the monkeys to
complete the number), and then place these two groups

' Travels in the Interior of South Africa, vol. ii. p. 207.

T The elephant which was killed at Exeter Change was estimated (being

partly weighed) at five tons and a half. The elephant actress, as I was

informed, weighed one ton less; so that we may take five as the average of

a full-grown elephant. I was told at the Surrey Gardens, that a hippopot-

, amus which was sent to England cut up into pieces was estimated at three
tons and a half; we will call it three. From these premises we may give
three tons and a half to each of the five rhinoceroses; perhaps a ton to the

, piraffe, and half to the bos caffer as well as to the elan (a large ox weighs
from 1200 to 1500 pounds). This will give an average (from the above
estimates) of 2.7 of a ton for the ten largest herbivorous animals of South-

6048
to 250, or 24 to i, for the ten largest animals from the two continents.

100 CHARLES DARWIN

alongside each other, it is not easy to conceive ranks more
disproportionate in size. After the above facts, we are com-
pelled to conclude, against anterior probability,8 that among
the mammalia there exists no close relation between the
bulk of the species, and the quantity of the vegetation, in
the countries which they inhabit.

With regard to the number of large quadrupeds, there
certainly exists no quarter of the globe which will bear com-
parison with Southern Africa. After the different state-
ments which have been given, the extremely desert character
of that region will not be disputed. In the European divi-
sion of the world, we must look back to the tertiary epochs,
to find a condition of things among the mammalia, resem-
bling that now existing at the Cape of Good Hope. Those
tertiary epochs, which we are apt to consider as abounding
to an astonishing degree with large animals, because we
find the remains of many ages accumulated at certain spots,
could hardly boast of more large quadrupeds than Southern
Africa does at present. If we speculate on the condition
of the vegetation during these epochs, we are at least bound
so far to consider existing analogies, as not to urge as
absolutely necessary a luxuriant vegetation, when we see
a state of things so totally different at the Cape of Good
Hope.

We know9 that the extreme regions of North America,
many degrees beyond the limit where the ground at the depth
of a few feet remains perpetually congealed, are covered by
forests of large and tall trees. In a like manner, in Siberia,
we have woods of birch, fir, aspen, and larch, growing in a
latitude10 (64°) where the mean temperature of the air falls
below the freezing point, and where the earth is so com-

8 If we suppose the case of the discovery of a skeleton of a Greenland
whale in a fossil state, not a single cetaceous animal being known to exist,
what naturalist would have ventured conjecture on the possibility of a
carcass so gigantic being supported on the minute Crustacea and mollusca
living in the frozen seas of the extreme North?

9 See Zoological Remarks to Capt. Back's Expedition, by Dr. Richardson.
He says, "The subsoil north of latitude 56° is perpetually frozen, the thaw
on the coast not penetrating above three feet, and at Bear Lake, in lati-
tude 64°, not more than twenty inches. The frozen substratum does not
of itself destroy vegetation, for forests flourish on the surface, at a distance
from the coast."

10 See Humboldt, Fragments Asiatiques, p. 386 : Barton's Geography of
Plants: and Malte Brun. In the latter work it is said that the limit of
the growth of trees in Siberia may be drawn under the parallel of 70°.

THE VOYAGE OF THE BEAGLE 101

pletely frozen, that the carcass of an animal embedded in it
is perfectly preserved. With these facts we must grant, as
far as quantity alone of vegetation is concerned, that the
great quadrupeds of the later tertiary epochs might, in most
parts of Northern Europe and Asia, have lived on the spots
where their remains are now found. I do not here speak of
the kind of vegetation necessary for their support; because,
as there is evidence of physical changes, and as the animals
have become extinct, so may we suppose that the species of
plants have likewise been changed.

These remarks, I may be permitted to add, directly bear
on the case of the Siberian animals preserved in ice. The
firm conviction of the necessity of a vegetation possessing
a character of tropical luxuriance, to support such large
animals, and the impossibility of reconciling this with the
proximity of perpetual congelation, was one chief cause of
the several theories of sudden revolutions of climate, and of
overwhelming catastrophes, which were invented to account
for their entombment. I am far from supposing that the
climate has not changed since the period when those ani-
mals lived, which now lie buried in the ice. At present I
only wish to show, that as far as quantity of food alone is
concerned, the ancient rhinoceroses might have roamed over
the steppes of central Siberia (the northern parts probably
being under water) even in their present condition, as well
as the living rhinoceroses and elephants over the Karros
of Southern Africa.

I will now give an account of the habits of some of the
more interesting birds which are common on the wild plains
of Northern Patagonia; and first for the largest, or South
American ostrich. The ordinary habits of the ostrich are
familiar to every one. They live on vegetable matter, such
as roots and grass; but at Bahia Blanca I have repeatedly
seen three or four come down at low water to the extensive
mud-banks which are then dry, for the sake, as the Gauchos
say, of feeding on small fish. Although the ostrich in its
habits is so shy, wary, and solitary, and although so fleet
in its pace, it is caught without much difficulty by the In-
dian or Gaucho armed with the bolas. When several horse-

102 CHARLES DARWIN

men appear in a semicircle, it becomes confounded, and does
not know which way to escape. They generally prefer run-
ning against the wind; yet at the first start they expand
their wings, and like a vessel make all sail. On one fine
hot day I saw several ostriches enter a bed of tall rushes,
where they squatted concealed, till quite closely approached.
It is not generally known that ostriches readily take to the
water. Mr. King informs me that at the Bay of San Bias,
and at Port Valdes in Patagonia, he saw these birds swim-
ming several times from island to island. They ran into
the water both when 'driven down to a point, and likewise
of their own accord when not frightened: the distance
crossed was about two hundred yards. When swimming,
very little of their bodies appear above water; their necks
are extended a little forward, and their progress is slow.
On two occasions I saw some ostriches swimming across the
Santa Cruz river, where its course was about four hundred
yards wide, and the stream rapid. Captain Sturt,u when
descending the Murrumbidgee, in Australia, saw two emus
in the act of swimming.

The inhabitants of the country readily distinguish, even
at a distance, the cock bird from the hen. The former is
larger and darker-coloured," and has a bigger head. The
ostrich, I believe the cock, emits a singular, deep-toned, hiss-
ing note: when first I heard it, standing in the midst of
some sand-hillocks, I thought it was made by some wild
beast, for it is a sound that one cannot tell whence it comes,
or from how far distant. When we were at Bahia Blanca
in the months of September and October, the eggs, in extra-
ordinary numbers, were found all over the country. They
lie either scattered and single, in which case they are never
hatched, and are called by the Spaniards huachos; or they
are collected together into a shallow excavation, which forms
the nest. Out of the four nests which I saw, three con-
tained twenty-two eggs each, and the fourth twenty-seven.
In one day's hunting on horseback sixty-four eggs were
found; forty- four of these were in two nests, and the re-
maining twenty, scattered huachos. The Gauchos unani-

11 Sturt's Travels, vol. ii. p. 74.

12 A Gaucho assured me that he had once seen a snow-white or Albinc
variety, and that it was a most beautiful bird.

THE VOYAGE OF THE BEAGLE 103

mously affirm, and there is no reason to doubt their state-
ment, that the male bird alone hatches the eggs, and for
some time afterwards accompanies the young. The cock
when on the nest lies very close ; I have myself almost ridden
over one. It is asserted that at such times they are occa-
sionally fierce, and even dangerous, and that they have been
known to attack a man on horseback, trying to kick and
leap on him. My informer pointed out to me an old man,
whom he had seen much terrified by one chasing him. I
observe in Burchell's travels in South Africa, that he re-
marks, " Having killed a male ostrich, and the feathers being
dirty, it was said by the Hottentots to be a nest bird." I
understand that the male emu in the Zoological Gardens
takes charge of the nest: this habit, therefore, is common
to the family.

The Gauchos unanimously affirm that several females
lay in one nest. I have been positively told that four or
five hen birds have been watched to go in the middle of the
day, one after the other, to the same nest. I may add, also,
that it is believed in Africa, that two or more females lay
in one nest.u Although this habit at first appears very
strange, I think the cause may be explained in a simple
manner. The number of eggs in the nest varies from twenty
to forty, and even to fifty; and according to Azara, some-
times to seventy or eighty. Now, although it is most prob-
able, from the number of eggs found in one district being
so extraordinarily great in proportion to the parent birds,
and likewise from the state of the ovarium of the hen, that
she may in the course of the season lay a large number, yet
the time required must be very long. Azara states,1* that a
female in a state of domestication laid seventeen eggs, each
at the interval of three days one from another. If the hen
was obliged to hatch her own eggs, before the last was laid
the first probably would be addled; but if each laid a few
eggs at successive periods, in different nests, and several
hens, as is stated to be the case, combined together, then
the eggs in one collection would be nearly of the same age.
If the number of eggs in one of these nests is, as I believe,
not greater on an average than the number laid by one

18 Burchell's Travels, vol. i. p. 280. u Azara, vol. iv. p. 173.

104 CHARLES DARWIN

female in the season, then there must be as many nests as
females, and each cock bird will have its fair share of the
labour of incubation; and that during a period when the
females probably could not sit, from not having finished
laying.16 I have before mentioned the great numbers of
huachos, or deserted eggs ; so that in one day's hunting
twenty were found in this state. It appears odd that so
many should be wasted. Does it not arise from the difficulty
of several females associating together, and finding a male
ready to undertake the office of incubation ? It is evident
that there must at first be some degree of association be-
tween at least two females ; otherwise the eggs would remain
scattered over the wide plain, at distances far too great to
allow of the male collecting them into one nest : some au-
thors have believed that the scattered eggs were deposited
for the young birds to feed on. This can hardly be the case
in America, because the huachos, although often found
addled and putrid, are generally whole.

When at the Rio Negro in Northern Patagonia, I re-
peatedly heard the Gauchos talking of a very rare bird which
they called Avestruz Petise. They described it as being less
than the common ostrich (which is there abundant), but
with a very close general resemblance. They said its colour
was dark and mottled, and that its legs were shorter, and
feathered lower down than those of the common ostrich.
It is more easily caught by the bolas than the other species.
The few inhabitants who had seen both kinds, affirmed they
could distinguish them apart from a long distance. The
eggs of the small species appeared, however, more generally
known; and it was remarked, with surprise, that they were
very little less than those of the Rhea, but of a slightly differ-
ent form, and with a tinge of pale blue. This species occurs
most rarely on the plains bordering the Rio Negro ; but about
a degree and a half further south they are tolerably abun-
dant. When at Port Desire, in Patagonia (lat. 48°), Mr.
Martens shot an ostrich; and I looked at it, forgetting at

the moment, in the most unaccountable manner, the whole
subject of the Petises, and thought it was a not full-grown
bird of the common sort. It was cooked and eaten before
my memory returned. Fortunately the head, neck, legs,
wings, many of the larger feathers, and a large part of the
skin, had been preserved; and from these a very nearly per-
fect specimen has been put together, and is now exhibited
in the museum of the Zoological Society. Mr. Gould, in de-
scribing this new species, has done me the honour of calling
it after my name.

Among the Patagonian Indians in the Strait of Magellan,
we found a half Indian, who had lived some years with
the tribe, but had been born in the northern provinces. I
asked him if he had ever heard of the Avestruz Petise? He
answered by saying, " Why, there are none others in these
southern countries." He informed me that the number of
eggs in the nest of the petise is considerably less than in that
of the other kind, namely, not more than fifteen on an aver-
age ; but he asserted that more than one female deposited
them. At Santa Cruz we saw several of these birds. They
were excessively wary: I think they could see a person ap-
proaching when too far off to be distinguished themselves.
In ascending the river few were seen ; but in our quiet and
rapid descent, many, in pairs and by fours or fives, were
observed. It was remarked that this bird did not expand
its wings, when first starting at full speed, after the manner
of the northern kind. In conclusion I may observe, that
the Struthio rhea inhabits the country of La Plata as far
as a little south of the Rio Negro in lat. 41°, and that the
Struthio Darwinii takes its place in Southern Patagonia;
the part about the Rio Negro being neutral territory. M.
A. d'Orbigny,16 when at the Rio Negro, made great exer-
tions to procure this bird, but never had the good fortune to
succeed. Dobrizhoffer" long ago was aware of there being
two kinds of ostriches; he says, "You must know, more-

18 When at the Rio Negro, we heard much of the indefatigable labours
of this naturalist. M. Alcide d'Orbigny, during the years 1825 to 1833,
traversed s_everal large portions of South America, and has made a collec-
tion, and is now publishing the results on a scale of magnificence, which
at once places himself in the list of American travellers second only to
Humboldt.

over, that Emus differ in size and habits in different tracts
of land; for those that inhabit the plains of Buenos Ayres
and Tucuman are larger, and have black, white and grey,
feathers; those near to the Strait of Magellan are smaller
and more beautiful, for their white feathers are tipped with
black at the extremity, and their black ones in like manner
terminate in white."

A very singular little bird, Tinochorus rumicivorus, is
here common : in its habits and general appearance, it nearly
equally partakes of the characters, different as they are, of
the quail and snipe. The Tinochorus is found in the whole
of southern South America, wherever there are sterile plains,
or open dry pasture land. It frequents in pairs or small
flocks the most desolate places, where scarcely another living
creature can exist. Upon being approached they squat close,
and then are very difficult to be distinguished from the
ground. When feeding they walk rather slowly, with their
legs wide apart. They dust themselves in roads and sandy
places, and frequent particular spots, where they may be
found day after day: like partridges, they take wing in a
flock. In all these respects, in the muscular gizzard adapted
for vegetable food, in the arched beak and fleshy nostrils,
short legs and form of foot, the Tinochorus has a close affin-
ity with quails. But as soon as the bird is seen flying, its
whole appearance changes; the long pointed wings, so dif-
ferent from those in the gallinaceous order, the irregular
manner of flight, and plaintive cry uttered at the moment
of rising, recall the idea of a snipe. The sportsmen of the
Beagle unanimously called it the short-billed snipe. To this
genus, or rather to the family of the Waders, its skeleton
shows that it is really related.

The Tinochorus is closely related to some other South
American birds. Two species of the genus Attagis are in
almost every respect ptarmigans in their habits; one lives
in Tierra del Fuego, above the limits of the forest land ; and
the other just beneath the snow-line on the Cordillera of
Central Chile. A bird of another closely allied genus, Chi-
onis alba, is an inhabitant of the antarctic regions; it feeds
on sea-weed and shells on the tidal rocks. Although not

THE VOYAGE OF THE BEAGLE 107

web-footed, from some unaccountable habit, it is frequently
met with far out at sea. This small family of birds is one
of those which, from its varied relations to other families,
although at present offering only difficulties to the sys-
tematic naturalist, ultimately may assist in revealing the
grand scheme, common to the present and past ages, on
which organized beings have been created.

The genus Furnarius contains several species, all small
birds, living on the ground, and inhabiting open dry coun-
tries. In structure they cannot be compared to any Eu-
ropean form. Ornithologists have generally included them
among the creepers, although opposed to that family in every
habit. The best known species is the common oven-bird of
La Plata, the Casara or housemaker of the Spaniards. The
nest, whence it takes its name, is placed in the most ex-
posed situations, as on the top of a post, a bare rock, or on
a cactus. It is composed of mud and bits of straw, and has
strong thick walls: in shape it precisely resembles an oven,
or depressed beehive. The opening is large and arched,
and directly in front, within the nest, there is a partition,
which reaches nearly to the roof, thus forming a passage
or antechamber to the true nest.

Another and smaller species of Furnarius (F. cunicu-
larius), resembles the oven-bird in the general reddish tint
of its plumage, in a peculiar shrill reiterated cry, and in an
odd manner of running by starts. From its affinity, the
Spaniards call it Casarita (or little housebuilder), although
its nidification is quite different. The Casarita builds its
nest at the bottom of a narrow cylindrical hole, which is
said to extend horizontally to nearly six feet under ground.
Several of the country people told me, that when boys, they
had attempted to dig out the nest, but had scarcely ever
succeeded in getting to the end of the passage. The bird
chooses any low bank of firm sandy soil by the side of a
road or stream. Here (at Bahia Blanca) the walls round
the houses are built of hardened mud; and I noticed that
one, which enclosed a courtyard where I lodged, was bored
through by round holes in a score of places. On asking the
owner the cause of this, he bitterly complained of the little
casarita, several of which I afterwards observed at work.

108 CHARLES DARWIN

It is rather curious to find how incapable these birds must
be of acquiring any notion of thickness, for although they
were constantly flitting over the low wall, they continued
vainly to bore through it, thinking it an excellent bank for
their nests. I do not doubt that each bird, as often as it
came to daylight on the opposite side, was greatly surprised
at the marvellous fact.

I have already mentioned nearly all the mammalia com-
mon in this country. Of armadilloes three species occur,
namely, the Dasypus minutus or pichy, the D. villosus or
peludo, and the apar. The first extends ten degrees further
south than any other kind ; a fourth species, the Mulita,
does not come as far south as Bahia Blanca. The four spe-
cies have nearly similar habits ; the peludo, however, is noc-
turnal, while the others wander by day over the open plains,
feeding on beetles, larvae, roots, and even small snakes. The
apar, commonly called mataco, is remarkable by having only
three moveable bands; the rest of its tesselated covering
being nearly inflexible. It has the power of rolling itself
into a perfect sphere, like one kind of English woodlouse.
In this state it is safe from the attack of dogs; for the dog
not being able to take the whole in its mouth, tries to bite
one side, and the ball slips away. The smooth hard cover-
ing of the mataco offers a better defence than the sharp
spines of the hedgehog. The pichy prefers a very dry soil;
and the sand-dunes near the coast, where for many months
it can never taste water, is its favourite resort: it often tries
to escape notice, by squatting close to the ground. In the
course of a day's ride, near Bahia Blanca, several were gen-
erally met with. The instant one was perceived, it was
necessary, in order to catch it, almost to tumble off one's
horse; for in soft soil the animal burrowed so quickly, that
its hinder quarters would almost disappear before one could
alight. It seems almost a pity to kill such nice little ani-
mals, for as a Gaucho said, while sharpening his knife on
the back of one, "Son tan mansos" (they are so quiet).

Of reptiles there are many kinds: one snake (a Trigono-
cephalus, or Cophias18), from the size of the poison channel
in its fangs, must be very deadly. Cuvier, in opposition to

13 M. Bibron calls it T. crepitans.

THE VOYAGE OF THE BEAGLE 109

some other naturalists, makes this a sub-genus of the rattle-
snake, and intermediate between it and the viper. In con-
firmation of this opinion, I observed a fact, which appears
to me very curious and instructive, as showing how every
character, even though it may be in some degree independ-
ent of structure, has a tendency to vary by slow degrees.
The extremity of the tail of this snake is terminated by a
point, which is very slightly enlarged; and as the animal
glides along, it constantly vibrates the last inch; and this
part striking against the dry grass and brushwood, produces
a rattling noise, which can be distinctly heard at the dis-
tance of six feet. As often as the animal was irritated or
surprised, its tail was shaken; and the vibrations were ex-
tremely rapid. Even as long as the body retained its irrita-
bility, a tendency to this habitual movement was evident.
This Trigonocephalus has, therefore, in some respects the
structure of a viper, with the habits of a rattlesnake: the
noise, however, being produced by a simpler device. The
expression of this snake's face was hideous and fierce ; the
pupil consisted of a vertical slit in a mottled and coppery
iris; the jaws were broad at the base, and the nose termi-
nated in a triangular projection. I do not think I ever saw
anything more ugly, excepting, perhaps, some of the vam-
pire bats. I imagine this repulsive aspect originates from
the features being placed in positions, with respect to each
other, somewhat proportional to those of the human face;
and thus we obtain a scale of hideousness.

Amongst the Batrachian reptiles, I found only one little
toad (Phryniscus nigricans), which was most singular from
its colour. If we imagine, first, that it had been steeped in
the blackest ink, and then, when dry, allowed to crawl over
a board, freshly painted with the brightest vermilion, so
as to colour the soles of its feet and parts of its stomach, a
good idea of its appearance will be gained. If it had been
an unnamed species, surely it ought to have been called
Diabolicus, for it is a fit toad to preach in the ear of Eve.
Instead of being nocturnal in its habits, as other toads are,
and living in damp obscure recesses, it crawls during the heat
of the day about the dry sand-hillocks and arid plains, where
not a single drop of water can be found. It must necessarily

110 CHARLES DARWIN

depend on the dew for its moisture; and this probably is
absorbed by the skin, for it is known, that these reptiles pos-
sess great powers of cutaneous absorption. At Maldonado,
I found one in a situation nearly as dry as at Bahia Blanca,
and thinking to give it a great treat, carried it to a pool of
water; not only, was the little animal unable to swim, but
I think without help it would soon have been drowned.

Of lizards there were many kinds, but only one (Proc-
totretus multimaculatus) remarkable from its habits. It
lives on the bare sand near the sea coast, and from its mot-
tled colour, the brownish scales being speckled with white,
yellowish red, and dirty blue, can hardly be distinguished
from the surrounding surface. When frightened, it at-
tempts to avoid discovery by feigning death, with out-
stretched legs, depressed body, and closed eyes: if further
molested, it buries itself with great quickness in the loose
sand. This lizard, from its flattened body and short legs,
cannot run quickly.

I will here add a few remarks on the hybernation of ani-
mals in this part of South America. When we first arrived
at Bahia Blanca, September 7th, 1832, we thought nature
had granted scarcely a living creature to this sandy and dry
country. By digging, however, in the ground, several in-
sects, large spiders, and lizards were found in a half-torpid
state. On the I5th, a few animals began to appear, and by
the 1 8th (three days from the equinox), everything an-
nounced the commencement of spring. The plains were or-
namented by the flowers of a pink wood-sorrel, wild peas,
cenotherae, and geraniums; and the birds began to lay their
eggs. Numerous Lamellicorn and Heteromerous insects, the
latter remarkable for their deeply sculptured bodies, were
slowly crawling about; while the lizard tribe, the constant
inhabitants of a sandy soil, darted about in every direction.
During the first eleven days, whilst nature was dormant, the
mean temperature taken from observations made every two
hours on board the Beagle, was 51°; and in the middle of
the day the thermometer seldom ranged above 55°. On the
eleven succeeding days, in which all living things became so
animated, the mean was 58°, and the range in the middle
of the day between 60° and 70°. Here, then, an increase of

THE VOYAGE OF THE BEAGLE HI

seven degrees in mean temperature, but a greater one of
extreme heat, was sufficient to awake the functions of life.
At Monte Video, from which we had just before sailed, in
the twenty-three days included between the 26th of July
and the igih of August, the mean temperature from 276 ob-
servations was 58°. 4; the mean hottest day being 65°. 5, and
the coldest 46°. The lowest point to which the thermometer
fell was 41 ".5, and occasionally in the middle of the day it
rose to 69° or 70°. Yet with this high temperature, almost
every beetle, several genera of spiders, snails, and land-shells,
toads and lizards were all lying torpid beneath stones. But
we have seen that at Bahia Blanca, which is four degrees
southward, and therefore with a climate only a very little
colder, this same temperature with a rather less extreme
heat, was sufficient to awake all orders of animated beings.
This shows how nicely the stimulus required to arouse hy-
bernating animals is governed by the usual climate of the
district, and not by the absolute heat. It is well known that
within the tropics, the hybernation, or more properly aestiva-
tion, of animals is determined not by the temperature, but
by the times of drought. Near Rio de Janeiro, I was at first
surprised to observe, that, a few days after some little de-
pressions had been filled with water, they were peopled by
numerous full-grown shells and beetles, which must have
been lying dormant. Humboldt has related the strange acci-
dent of a hovel having been erected over a spot where a
young crocodile lay buried in the hardened mud. He adds,
"The Indians often find enormous boas, which they call Uji,
or water serpents, in the same lethargic state. To reanimate
them, they must be irritated or wetted with water."

I will only mention one other animal, a zoophyte (I be-
lieve Virgularia Patagonica), a kind of sea-pen. It consists
of a thin, straight, fleshy stem, with alternate rows of polypi
on each side, and surrounding an elastic stony axis, varying
in length from eight inches to two feet. The stem at one ex-
tremity is truncate, but at the other is terminated by a
vermiform fleshy appendage. The stony axis which gives
strength to the stem may be traced at this extremity into a
mere vessel filled with granular matter. At low water hun-
dreds of these zoophytes might be seen, projecting like stub-

112 CHARLES DARWIN

ble, with the truncate end upwards, a few inches above the
surface of the muddy sand. When touched or pulled they
suddenly drew themselves in with force, so as nearly or quite
to disappear. By this action, the highly elastic axis must
be bent at the lower extremity, where it is naturally slightly
curved; and I imagine it is by this elasticity alone that the
zoophyte is enabled to rise again through the mud. Each
polypus, though closely united to its brethren, has a dis-
tinct mouth, body, and tentacula. Of these polypi, in a large
specimen, there must be many thousands ; yet we see that
they act by one movement: they have also one central axis
connected with a system of obscure circulation, and the ova
are produced in an organ distinct from the separate indi-
viduals.1' Well may one be allowed to ask, what is an indi-
vidual? It is always interesting to discover the foundation
of the strange tales of the old voyagers ; and I have no doubt
but that the habits of this Virgularia explain one such case.
Captain Lancaster, in his voyage20 in 1601, narrates that on
the sea-sands of the Island of Sombrero, in the East Indies,
he " found a small twig growing up like a young tree, and
on offering to pluck it up it shrinks down to the ground,
and sinks, unless held very hard. On being plucked up, a
great worm is found to be its root, and as the tree groweth
in greatness, so doth the worm diminish ; and as soon as the
worm is entirely turned into a tree it rooteth in the earth,
and so becomes great. This transformation is one of the
strangest wonders that I saw in all my travels: for if this
tree is plucked up, while young, and the leaves and bark
stripped off, it becomes a hard stone when dry, much like
white coral : thus is this worm twice transformed into

19 The cavities leading from the fleshy compartments of the extremity, were
filled with a yellow pulpy matter, which, examined under a microscope,
presented an extraordinary appearance. The mass consisted of rounded,
semi-transparent, irregular grains, aggregated together into particles of
various sizes. _ All such particles, and the separate grains, possessed the
power of rapid movement; generally revolving around different axes, but
sometimes progressive. The movement was visible with a very weak power,
but even with the highest its cause could not be perceived. It was very
different from the circulation of the fluid in the elastic bag, containing
the thin extremity of the axis. On other occasions, when dissecting small
marine animals beneath the microscope, I have seen particles of pulpy matter,
some of large size, as soon as they were disengaged, commence revolving.
1 have imagined, I know not with how much truth, that this granulo-
pulpy matter was in process of being converted into ova. Certainly in this
zoophyte such appeared to be the case.

different natures. Of these we gathered and brought home
many."

During my stay at Bahia Blanca, while waiting for the
Beagle, the place was in a constant state of excitement, from
rumours of wars and victories, between the troops of Rosas
and the wild Indians. One day an account came that a small
party forming one of the postas on the line to Buenos Ayres,
had been found all murdered. The next day three hundred
men arrived from the Colorado, under the command of Com-
mandant Miranda. A large portion of these men were In-
dians (mansos, or tame), belonging to the tribe of the Ca-
cique Bernantio. They passed the night here; and it was
impossible to conceive anything more wild and savage than
the scene of their bivouac. Some drank till they were
intoxicated; others swallowed the steaming blood of the
cattle slaughtered for their suppers, and then, being sick
from drunkenness, they cast it up again, and were besmeared
with filth and gore.

Nam simul expletus dapibus, vinoque sepultus
Cervicem inflexam posuit, jacuitque per antrum
Immensus, saniem eructans, ac frusta cruenta
Per somnum commixta mero.

In the morning they started for the scene of the murder,
with orders to follow the "rastro," or track, even if it led
them to Chile. We subsequently heard that the wild In-
dians had escaped into the great Pampas, and from some
cause the track had been missed. One glance at the rastro
tells these people a whole history. Supposing they examine
the track of a thousand horses, they will soon guess the num-
ber of mounted ones by seeing how many have cantered ; by
the depth of the other impressions, whether any horses were
loaded with cargoes; by the irregularity of the footsteps,
how far tired; by the manner in which the food has been
cooked, whether the pursued travelled in haste; by the gen-
eral appearance, how long it has been since they passed.
They consider a rastro of ten days or a fortnight, quite
recent enough to be hunted out. We also heard that Miranda
struck from the west end of the Sierra Ventana, in a direct

114 CHARLES DARWIN

line to the island of Cholechel, situated seventy leagues up
the Rio Negro. This is a distance of between two and three
hundred miles, through a country completely unknown.
What other troops in the world are so independent? With
the sun for their guide, mare's flesh for food, their saddle-
cloths for beds, — as long as there is a little water, these men
would penetrate to the end of the world.

A few days afterwards I saw another troop of these ban-
ditti-like soldiers start on an expedition against a tribe of
Indians at the small Salinas, who had been betrayed by a
prisoner cacique. The Spaniard who brought the orders
for this expedition was a very intelligent man. He gave
me an account of the last engagement at which he was pres-
ent. Some Indians, who had been taken prisoners, gave
information of a tribe living north of the Colorado. Two
hundred soldiers were sent; and they first discovered the
Indians by a cloud of dust from their horses' feet, as they
chanced to be travelling. The country was mountainous and
wild, and it must have been far in the interior, for the Cor-
dillera were in sight. The Indians, men, women, and chil-
dren, were about one hundred and ten in number, and they
were nearly all taken or killed, for the soldiers sabre every
man. The Indians are now so terrified that they offer no
resistance in a body, but each flies, neglecting even his wife
and children; but when overtaken, like wild animals, they
fight against any number to the last moment. One dying In-
dian seized with his teeth the thumb of his adversary, and
allowed his own eye to be forced out sooner than relinquish
his hold. Another, who was wounded, feigned death, keeping
a knife ready to strike one more fatal blow. My informer
said, when he was pursuing an Indian, the man cried out
for mercy, at the same time that he was covertly loosing the
bolas from his waist, meaning to whirl it round his head and
so strike his pursuer. " I however struck him with my sabre
to the ground, and then got off my horse, and cut his throat
with my knife." This is a dark picture ; but how much more
shocking is the unquestionable fact, that all the women who
appear above twenty years old are massacred in cold blood !
When I exclaimed that this appeared rather inhuman, he
answered, " Why, what can be done ? they breed so ! "

THE VOYAGE OF THE BEAGLE US

Every one here is fully convinced that this is the most
just war, because it is against barbarians. Who would
believe in this age that such atrocities could be committed in
a Christian civilized country? The children of the Indians
are saved, to be sold or given away as servants, or rather
slaves for as long a time as the owners can make them
believe themselves slaves; but I believe in their treatment
there is little to complain of.

In the battle four men ran away together. They were
pursued, one was killed, and the other three were taken alive.
They turned out to be messengers or ambassadors from a
large body of Indians, united in the common cause of
defence, near the Cordillera. The tribe to which they had
been sent was on the point of holding a grand council; the
feast of mare's flesh was ready, and the dance prepared: in
the morning the ambassadors were to have returned to the
Cordillera. They were remarkably fine men, very fair, above
six feet high, and all under thirty years of age. The three
survivors of course possessed very valuable information ; and
to extort this they were placed in a line. The two first being
questioned, answered, "No se " (I do not know), and were
one after the other shot. The third also said " No se ; " add-
ing, " Fire, I am a man, and can die ! " Not one syllable
would they breathe to injure the united cause of their coun-
try ! The conduct of the above-mentioned cacique was very
different; he saved his life by betraying the intended plan
of warfare, and the point of union in the Andes. It was
believed that there were already six or seven hundred In-
dians together, and that in summer their numbers would be
doubled. Ambassadors were to have been sent to the Indians
at the small Salinas, near Bahia Blanca, whom I have men-
tioned that this same cacique had betrayed. The communi-
cation, therefore, between the Indians, extends from the
Cordillera to the coast of the Atlantic.

General Rosas's plan is to kill all stragglers, and having
driven the remainder to a common point, to attack them in
a body, in the summer, with the assistance of the Chilenos.
This operation is to be repeated for three successive years.
I imagine the summer is chosen as the time for the main
attack, because the plains are then without water, and the

116 CHARLES DARWIN

Indians can only travel in particular directions. The escape
of the Indians to the south of the Rio Negro, where in such
a vast unknown country they would be safe, is prevented by
a treaty with the Tehuelches to this effect ; — that Rosas pays
them so much to slaughter every Indian who passes to the
south of the river, but if they fail in so doing, they them-
selves are to be exterminated. The war is waged chiefly
against the Indians near the Cordillera; for many of the
tribes on this eastern side are fighting with Rosas. The
' general, however, like Lord Chesterfield, thinking that his
friends may in a future day become his enemies, always
places them in the front ranks, so that their numbers may
be thinned. Since leaving South America we have heard
that this war of extermination completely failed.

Among the captive girls taken in the same engagement,
there were two very pretty Spanish ones, who had been car-
ried away by the Indians when young, and could now only
speak the Indian tongue. From their account they must
have come from Salta, a distance in a straight line of nearly
one thousand miles. This gives one a grand idea of the
immense territory over which the Indians roam: yet, great
as it is, I think there will not, in another half-century, be
a wild Indian northward of the Rio Negro. The warfare
is too bloody to last; the Christians killing every Indian,
and the Indians doing the same by the Christians. It is
melancholy to trace how the Indians have given way before
the Spanish invaders. Schirdel21 says that in 1535, when
Buenos Ayres was founded, there were villages containing
two and three thousand inhabitants. Even in Falconer's
time (1750) the Indians made inroads as far as Luxan,
Areco, and Arrecife, but now they are driven beyond the
Salado. Not only have whole tribes been exterminated, but
the remaining Indians have become more barbarous : instead
of living in large villages, and being employed in the arts of
fishing, as well as of the chase, they now wander about the
open plains, without home or fixed occupation.

I heard also some account of an engagement which took
place, a few weeks previously to the one mentioned, at
Cholechel. This is a very important station on account of

"Purchas's Collection of Voyages. I believe the date was really 1537.

THE VOYAGE OF THE BEAGLE 117

being a pass for horses; and it was, in consequence, for
some time the head-quarters of a division of the army.
When the troops first arrived there they found a tribe of
Indians, of whom they killed twenty or thirty. The cacique
escaped in a manner which astonished every one. The chief
Indians always have one or two picked horses, which they
keep ready for any urgent occasion. On one of these, an old
white horse, the cacique sprung, taking with him his little
son. The horse had neither saddle nor bridle. To avoid the
shots, the Indian rode in the peculiar method of his nation ;
namely, with an arm round the horse's neck, and one leg
only on its back. Thus hanging on one side, he was seen
patting the horse's head, and talking to him. The pursuers
urged every effort in the chase; the Commandant three
times changed his horse, but all in vain. The old Indian
father and his son escaped, and were free. What a fine pic-
ture one can form in one's mind, — the naked, bronze-like
figure of the old man with his little boy, riding like a
Mazeppa on the white horse, thus leaving far behind him the
host of his pursuers!

I saw one day a soldier striking fire with a piece of flint,
which I immediately recognised as having been a part of the
head of an arrow. He told me it was found near the island
of Cholechel, and that they are frequently picked up there.
It was between two and three inches long, and therefore
twice as large as those now used in Tierra del Fuego : it was
made of opaque cream-coloured flint, but the point and barbs
had been intentionally broken off. It is well known that no
Pampas Indians now use bows and arrows. I believe a small
tribe in Banda Oriental must be excepted; but they are
widely separated from the Pampas Indians, and border close
on those tribes that inhabit the forest, and live on foot. It
appears, therefore, that these arrow-heads are antiquarian1*
relics of the Indians, before the great change in habits
consequent on the introduction of the horse into South
America.

™ Azara has even doubted whether the Pampas Indians ever used bows.

i8th. — I hired a Gaucho to accompany me
on my ride to Buenos Ayres, though with some diffi-
culty, as the father of one man was afraid to let him
go, and another, who seemed willing, was described to me
as so fearful, that I was afraid to take him, for I was told
that even if he saw an ostrich at a distance, he would mis-
take it for an Indian, and would fly like the wind away.
The distance to Buenos Ayres is about four hundred miles,
and nearly the whole way through an uninhabited country.
We started early in the morning; ascending a few hundred
feet from the basin of green turf on which Bahia Blanca
stands, we entered on a wide desolate plain. It consists of
a crumbling argillaceo-calcareous rock, which, from the dry
nature of the climate, supports only scattered tufts of with-
ered grass, without a single bush or tree to break the monot-
onous uniformity. The weather was fine, but the atmos-
phere remarkably hazy; I thought the appearance foreboded
a gale, but the Gauchos said it was owing to the plain, at
some great distance in the interior, being on fire. After a
long gallop, having changed horses twice, we reached the Rio
Sauce : it is a deep, rapidj little stream, not above twenty-five
feet wide. The second posta on the road to Buenos Ayres
stands on its banks ; a little above there is a ford for horses,
where the water does not reach to the horses' belly ; but from
that point, in its course to the sea, it is quite impassable,
and hence makes a most useful barrier against the Indians-

118

THE VOYAGE OF THE BEAGLE 119

Insignificant as this stream is, the Jesuit Falconer, whose
information is generally so very correct, figures it as a con-
siderable river, rising at the foot of the Cordillera. With
respect to its source, I do not doubt that this is the case;
for the Gauchos assured me, that in the middle of the dry
summer, this stream, at the same time with the Colorado,
has periodical floods; which can only originate in the snow
melting on the Andes. It is extremely improbable that a
stream so small as the Sauce then was, should traverse the
entire width of the continent; and indeed, if it were the
residue of a large river, its waters, as in other ascertained
cases, would be saline. During the winter we must look to
the springs round the Sierra Ventana as the source of its
pure and limpid stream. I suspect the plains of Patagonia,
like those of Australia, are traversed by many water-courses,
which only perform their proper parts at certain periods.
Probably this is the case with the water which flows into the
head of Port Desire, and likewise with the Rio Chupat, on
the banks of which masses of highly cellular scoria? were
found by the officers employed in the survey.

As it was early in the afternoon when we arrived, we
took fresh horses, and a soldier for a guide, and started for
the Sierra de la Ventana. This mountain is visible from
the anchorage at Bahia Blanca; and Capt. Fitz Roy cal-
culates its height to be 3340 feet — an altitude very remark-
able on this eastern side of the continent. I am not aware
that any foreigner, previous to my visit, had ascended this
mountain; and indeed very few of the soldiers at Bahia
Blanca knew anything about it. Hence we heard of beds
of coal, of gold and silver, of caves, and of forests, all of
which inflamed my curiosity, only to disappoint it. The
distance from the posta was about six leagues, over a level
plain of the same character as before. The ride was, how-
ever, interesting, as the mountain began to show its true
form. When we reached the foot of the main ridge, we had
much difficulty in finding any water, and we thought we
should have been obliged to have passed the night without
any. At last we discovered some by looking close to the
mountain, for at the distance even of a few hundred yards,
the streamlets were buried and entirely lost in the friable

120 CHARLES DARWIN

calcareous stone and loose detritus. I do not think Nature
ever made a more solitary, desolate pile of rock; — it well
deserves its name of Hurtado, or separated. The mountain
is steep, extremely rugged, and broken, and so entirely desti-
tute of trees, and even bushes, that we actually could not
make a skewer to stretch out our meat over the fire of thistle-
stalks.1 The strange aspect of this mountain is contrasted
by the sea-like plain, which not only abuts against its steep
sides, but likewise separates the parallel ranges. The uni-
formity of the colouring gives an extreme quietness to the
view; — the whitish grey of the quartz rock, and the light
brown of the withered grass of the plain, being unrelieved
by any brighter tint. From custom, one expects to see in
the neighbourhood of a lofty and bold mountain, a broken
country strewed over with huge fragments. Here nature
shows that the last movement before the bed of the sea is
changed into dry land may sometimes be one of tranquillity.
Under these circumstances I was curious to observe how
far from the parent rock any pebbles could be found. On
the shores of Bahia Blanca, and near the settlement, there
were some of quartz, which certainly must have come from
this source: the distance is forty-five miles.

The dew, which in the early part of the night wetted the
saddle-cloths under which we slept, was in the morning
frozen. The plain, though appearing horizontal, had in-
sensibly sloped up to a height of between 800 and 900 feet
above the sea. In the morning (gth of September) the guide
told me to ascend the nearest ridge, which he thought would
lead me to the four peaks that crown the summit. The climb-
ing up such rough rocks was very fatiguing; the sides
were so indented, that what was gained in one five minutes
was often lost in the next. At last, when I reached the ridge,
my disappointment was extreme in finding a precipitous
valley as deep as the plain, which cut the chain transversely
in two, and separated me from the four points. This valley
is very narrow, but flat-bottomed, and it forms a fine horse-
pass for the Indians, as it connects the plains on the north-
ern and southern sides of the range. Having descended, and

a species of Eryngium.

THE VOYAGE OF THE BEAGLE 121

while crossing it, I saw two horses grazing: I immediately
hid myself in the long grass, and began to reconnoitre; but
as I could see no signs of Indians I proceeded cautiously on
my second ascent. It was late in the day, and this part of
the mountain, like the other, was steep and rugged. I was
on the top of the second peak by two o'clock, but got there
with extreme difficulty; every twenty yards I had the cramp
in the upper part of both thighs, so that I was afraid I
should not have been able to have got down again. It was
also necessary to return by another road, as it was out of
the question to pass over the saddle-back. I was therefore
obliged to give up the two higher peaks. Their altitude was
but little greater, and every purpose of geology had been
answered; so that the attempt was not worth the hazard
of any further exertion. I presume the cause of the cramp
was the great change in the kind of muscular action, from
that of hard riding to that of still harder climbing. It is
a lesson worth remembering, as in some cases it might cause
much difficulty.

I have already said the mountain is composed of white
quartz rock, and with it a little glossy clay-slate is associ-
ated. At the height of a few hundred feet above the plain,
patches of conglomerate adhered in several places to the
solid rock. They resembled in hardness, and in the nature
of the cement, the masses which may be seen daily forming
on some coasts. I do not doubt these pebbles were in a simi-
lar manner aggregated, at a period when the great calcare-
ous formation was depositing beneath the surrounding sea.
We may believe that the jagged and battered forms of the
hard quartz yet show the effects of the waves of an open
ocean.

I was, on the whole, disappointed with this ascent. Even
the view was insignificant ; — a plain like the sea, but with-
out its beautiful colour and defined outline. The scene, how-
ever, was novel, and a little danger, like salt to meat, gave
it a relish. That the danger was very little was certain, for
my two companions made a good fire — a thing which is never
done when it is suspected that Indians are near. I reached
the place of our bivouac by sunset, and drinking much mate,
and smoking several cigaritos, soon made up my bed for the

122 CHARLES DARWIN

night. The wind was very strong and cold, but I never slept
more comfortably.

September loth. — In the morning, having fairly scudded
before the gale, we arrived by the middle of the day at the
Sauce posta. On the road we saw great numbers of deer,
and near the mountain a guanaco. The plain, which abuts
against the Sierra, is traversed by some curious gullies, of
which one was about twenty feet wide, and at least thirty
deep ; we were obliged in consequence to make a considerable
circuit before we could find a pass. We stayed the night
at the posta, the conversation, as was generally the case,
being about the Indians. The Sierra Ventana was formerly
a great place of resort; and three or four years ago there
was much fighting there. My guide had been present when
many Indians were killed: the women escaped to the top of
the ridge, and fought most desperately with great stones;
many thus saving themselves.

September nth. — Proceeded to the third posta in com-
pany with the lieutenant who commanded it. The distance
is called fifteen leagues; but it is only guess-work, and is
generally overstated. The road was uninteresting, over a
dry grassy plain; and on our left hand at a greater or less
distance there were some low hills ; a continuation of which
we crossed close to the posta. Before our arrival we met
a large herd of cattle and horses, guarded by fifteen soldiers ;
but we were told many had been lost. It is very difficult to
drive animals across the plains; for if in the night a puma,
or even a fox, approaches, nothing can prevent the horses
dispersing in every direction ; and a storm will have the
same effect. A short time since, an officer left Buenos Ayres
with five hundred horses, and when he arrived at the army
he had under twenty.

Soon afterwards we perceived by the cloud of dust, that
a party of horsemen were coming towards us; when far dis-
tant my companions knew them to be Indians, by their long
hair streaming behind their backs. The Indians generally
have a fillet round their heads, but never any covering; and
their black hair blowing across their swarthy faces, height-
ens to an uncommon degree the wildness of their appearance.
They turned out to be a party of Bernantio's friendly tribe,

THE VOYAGE OF THE BEAGLE 123

going to a salina for salt. The Indians eat much salt, their
children sucking it like sugar. This habit is very different
from that of the Spanish Gauchos, who, leading the same
kind of life, eat scarcely any; according to Mungo Park,8
it is people who live on vegetable food who have an uncon-
querable desire for salt. The Indians gave us good-humoured
nods as they passed at full gallop, driving before them a
troop of horses, and followed by a train of lanky dogs.

September I2th and i^th. — I stayed at this posta two days,
waiting for a troop of soldiers, which General Rosas had
the kindness to send to inform me, would shortly travel to
Buenos Ayres; and he advised me to take the opportunity
of the escort. In the morning we rode to some neighbouring
hills to view the country, and to examine the geology. After
dinner the soldiers divided themselves into two parties for
a trial of skill with the bolas. Two spears were stuck in
the ground twenty-five yards apart, but they were struck
and entangled only once in four or five times. The balls can
be thrown fifty or sixty yards, but with little certainty. This,
however, does not apply to a man on horseback; for when
the speed of the horse is added to the force of the arm, it
is said, that they can be whirled with effect to the distance
of eighty yards. As a proof of their force, I may mention,
that at the Falkland Islands, when the Spaniards murdered
some of their own countrymen and all the Englishmen, a
young friendly Spaniard was running away, when a great
tall man, by name Luciano, came at full gallop after him,
shouting to him to stop, and saying that he only wanted to
speak to him. Just as the Spaniard was on the point of
reaching the boat, Luciano threw the balls: they struck him
on the legs with such a jerk, as to throw him down and
to render him for some time insensible. The man, after
Luciano had had his talk, was allowed to escape. He told
us that his legs were marked by great weals, where the thong
had wound round, as if he had been flogged with a whip.
In the middle of the day two men arrived, who brought a
parcel from the next posta to be forwarded to the general:
so that besides these two, our party consisted this evening
of my guide and self, the lieutenant, and his four soldiers.
8 Travels in Africa, p. 333.

124 CHARLES DARWIN

The latter were strange beings ; the first a fine young negro ;
the second half Indian and negro; and the two others non-
descripts ; namely, an old Chilian miner, the colour of ma-
hogany, and another partly a mulatto; but two such mon-
grels, with such detestable expressions, I never saw before.
At night, when they were sitting round the fire, and playing
at cards, I retired to view such a Salvator Rosa scene. They
were seated under a low cliff, so that I could look down
upon them; around the party were lying dogs, arms, rem-
nants of deer and ostriches ; and their long spears were stuck
in the turf. Further in the dark background, their horses
were tied up, ready for any sudden danger. If the stillness
of the desolate plain was broken by one of the dogs barking,
a soldier, leaving the fire, would place his head close to the
ground, and thus slowly scan the horizon. Even if the noisy
teru-tero uttered its scream, there would be a pause in the
conversation, and every head, for a moment, a little inclined.

What a life of misery these men appear to us to lead !
They were at least ten leagues from the Sauce posta, and
since the murder committed by the Indians, twenty from
another. The Indians are supposed to have made their at-
tack in the middle of the night; for very early in the morn-
ing after the murder, they were luckily seen approaching
this posta. The whole party here, however, escaped, together
with the troop of horses ; each one taking a line for himself,
and driving with him as many animals as he was able to
manage.

The little hovel, built of thistle-stalks, in which they slept,
neither kept out the wind nor rain ; indeed in the latter case
the only effect the roof had, was to condense it into larger
drops. They had nothing to eat excepting what they could
catch, such as ostriches, deer, armadilloes, etc., and their
only fuel was the dry stalks of a small plant, somewhat re-
sembling an aloe. The sole luxury which these men enjoyed
was smoking the little paper cigars, and sucking mate. I
used to think that the carrion vultures, man's constant at-
tendants on these dreary plains, while seated on the little
neighbouring cliffs seemed by their very patience to say,
" Ah ! when the Indians come we shall have a feast."

In the morning we all sallied forth to hunt, and although

THE VOYAGE OF THE BEAGLE 125

we had not much success, there were some animated chases.
Soon after starting the party separated, and so arranged
their plans, that at a certain time of the day (in guessing
which they show much skill) they should all meet from dif-
ferent points of the compass on a plain piece of ground,
and thus drive together the wild animals. One day I went
out hunting at Bahia Blanca, but the men there merely rode
in a crescent, each being about a quarter of a mile apart
from the other. A fine male ostrich being turned by the
headmost riders, tried to escape on one side. The Gauchos
pursued at a reckless pace, twisting their horses about with
the most admirable command, and each man whirling the
balls round his head. At length the foremost threw them,
revolving through the air: in an instant the ostrich rolled
over and over, its legs fairly lashed together by the thong.

The plains abound with three kinds of partridge,3 two
of which are as large as hen pheasants. Their destroyer,
a small and pretty fox, was also singularly numerous; in
the course of the day we could not have seen less than forty
or fifty. They were generally near their earths, but the dogs
killed one. When we returned to the posta, we found two
of the party returned who had been hunting by themselves.
They had killed a puma, and had found an ostrich's nest with
twenty-seven eggs in it. Each of these is said to equal in
weight eleven hen's eggs ; so that we obtained from this one
nest as much food as 297 hen's eggs would have given.

September i^th. — As the soldiers belonging to the next
posta meant to return, and we should together make a party
of five, and all armed, I determined not to wait for the ex-
pected troops. My host, the lieutenant, pressed me much
to stop. As he had been very obliging — not only providing
me with food, but lending me his private horses — I wanted
to make him some remuneration. I asked my guide whether
I might do so, but he told me certainly not; that the only
answer I should receive, probably would be, " We have meat
for the dogs in our country, and therefore do not grudge it
to a Christian." It must not be supposed that the rank of
lieutenant in such an army would at all prevent the accept-

can only be called a partridge with regard to its habits.

126 CHARLES DARWIN

ance of payment: it was only the high sense of hospitality,
which every traveller is bound to acknowledge as nearly uni-
versal throughout these provinces. After galloping some
leagues, we came to a low swampy country, which extends
for nearly eighty miles northward, as far as the Sierra Ta-
palguen. In some parts there were fine damp plains, covered
with grass, while others had a soft, black, and peaty soil.
There were also many extensive but shallow lakes, and large
beds of reeds. The country on the whole resembled the bet-
ter parts of the Cambridgeshire fens. At night we had some
difficulty in finding amidst the swamps, a dry place for our
bivouac.

September i5th. — Rose very early in the morning and
shortly after passed the posta where the Indians had mur-
dered the five soldiers. The officer had eighteen chuzo
wounds in his body. By the middle of the day, after a hard
gallop, we reached the fifth posta : on account of some diffi-
culty in procuring horses we stayed there the night. As this
point was the most exposed on the whole line, twenty-one
soldiers were stationed here; at sunset they returned from
hunting, bringing with them seven deer, three ostriches, and
many armadilloes and partridges. When riding through the
country, it is a common practice to set fire to the plain ;
and hence at night, as on this occasion, the horizon was
illuminated in several places by brilliant conflagrations.
This is done partly for the sake of puzzling any stray In-
dians, but chiefly for improving the pasture. In grassy
plains unoccupied by the larger ruminating quadrupeds, it
seems necessary to remove the superfluous vegetation by fire,
so as to render the new year's growth serviceable.

The rancho at this place did not boast even of a roof,
but merely consisted of a ring of thistle-stalks, to break
the force of the wind. It was situated on the borders of an
extensive but shallow lake, swarming with wild fowl, among
which the black-necked swan was conspicuous.

The kind of plover, which appears as if mounted on
stilts (Himantopus nigricollis), is here common in flocks of
considerable size. It has been wrongfully accused of in-
elegance; when wading about in shallow water, which is its
favourite resort, its gait is far from awkward. These birds

THE VOYAGE OF THE BEAGLE 127

in a flock utter a noise, that singularly resembles the cry of
a pack of small dogs in full chase: waking in the night, I
have more than once been for a moment startled at the dis-
tant sound. The teru-tero (Vanellus cayanus) is another
bird, which often disturbs the stillness of the night. In ap-
pearance and habits it resembles in many respects our pee-
wits; its wings, however, are armed with sharp spurs, like
those on the legs of the common cock. As our peewit takes
its name from the sound of its voice, so does the teru-tero.
While riding over the grassy plains, one is constantly pur-
sued by these birds, which appear to hate mankind, and I
am sure deserve to be hated for their never-ceasing, unvaried,
harsh screams. To the sportsman they are most annoying,
by telling every other bird and animal of his approach: to
the traveller in the country, they may possibly, as Molina
says, do good, by warning him of the midnight robber. Dur-
ing the breeding season, they attempt, like our peewits, by
feigning to be wounded, to draw away from their nests dogs
and other enemies. The eggs of this bird are esteemed a
great delicacy.

September i6th. — To the seventh posta at the foot of the
Sierra Tapalguen. The country was quite level, with a
coarse herbage and a soft peaty soil. The hovel was here
remarkably neat, the posts and rafters being made of about
a dozen dry thistle-stalks bound together with thongs of
hide; and by the support of these Ionic-like columns, the
roof and sides were thatched with reeds. We were here told
a fact, which I would not have credited, if I had not had
partly ocular proof of it; namely, that, during the previous
night hail as large as small apples, and extremely hard, had
fallen with such violence, as to kill the greater number of the
wild animals. One of the men had already found thirteen
deer (Cervus campestris) lying dead, and I saw their fresh
hides; another of the party, a few minutes after my arrival,
brought in seven more. Now I well know, that one man
without dogs could hardly have killed seven deer in a week.
The men believed they had seen about fifteen ostriches (part
of one of which we had for dinner) ; and they said that
several were running about evidently blind in one eye.
Numbers of smaller birds, as ducks, hawks, and partridges,

128 CHARLES DARWIN

were killed. I saw one of the latter with a black mark on
its bacL, as if it had been struck with a paving-stone. A
fence of thistle-stalks round the hovel was nearly broken
down, and my informer, putting his head out to see what was
the matter, received a severe cut, and now wore a bandage.
The storm was said to have been of limited extent: we
certainly saw from our last night's bivouac a dense cloud
and lightning in this direction. It is marvellous how such
strong animals as deer could thus have been killed; but I
have no doubt, from the evidence I have given, that the
story is not in the least exaggerated. I am glad, however,
to have its credibility supported by the Jesuit Dobrizhoffen/
who, speaking of a country much to the northward, says,
hail fell of an enormous size and killed vast numbers of cattle :
the Indians hence called the place Lalegraicavalca, meaning
" the little white things." Dr. Malcolmson, also, informs me
that he witnessed in 1831 in India, a hail-storm, which
killed numbers of large birds and much injured the cattle.
These hailstones were flat, and one was ten inches in cir-
cumference, and another weighed two ounces. They
ploughed up a gravel-walk like musket-balls, and passed
through glass-windows, making round holes, but not crack-
ing them.

Having finished our dinner, of hail-stricken meat, we
crossed the Sierra Tapalguen; a low range of hills, a few
hundred feet in height, which commences at Cape Corrientes.
The rock in this part is pure quartz ; further eastward I
understand it is granitic. The hills are of a remarkable
form; they consist of flat patches of table-land, surrounded
by low perpendicular cliffs, like the outliers of a sedimentary
deposit. The hill which I ascended was very small, not
above a couple of hundred yards in diameter; but I saw
others larger. One which goes by the name of the " Corral,"
is said to be two or three miles in diameter, and encompassed
by perpendicular cliffs, between thirty and forty feet high,
excepting at one spot, where the entrance lies. Falconer5
gives a curious account of the Indians driving troops of
wild horses into it, and then by guarding the entrance, keep-

ing them secure. I have never heard of any other instance
of table-land in a formation of quartz, and which, in the
hill I examined, had neither cleavage nor stratification. I
was told that the rock of the " Corral " was white, and would
strike fire.

We did not reach the posta on the Rio Tapalguen till
after it was dark. At supper, from something which was
said, I was suddenly struck with horror at thinking that I
was eating one of the favourite dishes of the country,
namely, a half-formed calf, long before its proper time of
birth. It turned out to be Puma; the meat is very white,
and remarkably like veal in taste. Dr. Shaw was laughed
at for stating that " the flesh of the lion is in great esteem,
having no small affinity with veal, both in colour, taste,
and flavour." Such certainly is the case with the Puma.
The Gauchos differ in their opinion, whether the Jaguar is
good eating, but are unanimous in saying that cat is ex-
cellent.

September ifth. — We followed the course of the Rio
Tapalguen, through a very fertile country, to the ninth
posta. Tapalguen, itself, or the town of Tapalguen, if it
may be so called, consists of a perfectly level plain, studded
over, as far as the eye can reach, with the toldos or oven-
shaped huts of the Indians. The families of the friendly
Indians, who were fighting on the side of Rosas, resided
here. We met and passed many young Indian women, rid-
ing by two or three together on the same horse: they, as
well as many of the young men, were strikingly handsome, —
their fine ruddy complexions being the picture of health.
Besides the toldos, there were three ranches; one inhabited
by the Commandant, and the two others by Spaniards with
small shops.

We were here able to buy some biscuit. I had now been
several days without tasting anything besides meat: I did
not at all dislike this new regimen ; but I felt as if it would
only have agreed with me with hard exercise. I have heard
that patients in England, when desired to confine themselves
exclusively to an animal diet, even with the hope of life
before their eyes, have hardly been able to endure it. Yet
the Gaucho in the Pampas, for months together, touches

nothing but beef. But they eat, I observe, a very large
proportion of fat, which is of a less animalized nature; and
they particularly dislike dry meat, such as that of the Agouti.
Dr. Richardson,* also, has remarked, " that when people
have fed for a long time solely upon lean animal food, the
desire for fat becomes so insatiable, that they can consume
a large quantity of unmixed and even oily fat without
nausea:" this appears to me a curious physiological fact.
It is, perhaps, from their meat regimen that the Gauchos,
like other carnivorous animals, can abstain long from food.
I was told that at Tandeel, some troops voluntarily pursued
a party of Indians for three days, without eating or drinking.

We saw in the shops many articles, such as horsecloths,
belts, and garters, woven by the Indian women. The pat-
terns were very pretty, and the colours brilliant; the work-
manship of the garters was so good that an English mer-
chant at Buenos Ayres maintained they must have been
manufactured in England, till he found the tassels had been
fastened by split sinew.

September i8th. — We had a very long ride this day. At
the twelfth posta, which is seven leagues south of the Rio
Salado, we came to the first estancia with cattle and white
women. Afterwards we had to ride for many miles through
a country flooded with water above our horses' knees. By
crossing the stirrups, and riding Arab-like with our legs
bent up, we contrived to keep tolerably dry. It was nearly
dark when we arrived at the Salado; the stream was deep,
and about forty yards wide; in summer, however, its bed
becomes almost dry, and the little remaining water nearly
as salt as that of the sea. We slept at one of the great estan-
cias of General Rosas. It was fortified, and of such an
extent, that arriving in the dark I thought it was a town
and fortress. In the morning we saw immense herds of
cattle, the general here having seventy-four square leagues
of land. Formerly nearly three hundred men were em-
ployed about this estate, and they defied all the attacks of
the Indians.

September ipth. — Passed the Guardia del Monte. This
is a nice scattered little town, with many gardens, full of

peach and quince trees. The plain here looked like that
around Buenos Ayres ; the turf being short and bright green,
with beds of clover and thistles, and with bizcacha holes.
I was very much struck with the marked change in the
aspect of the country after having crossed the Salado. From
a coarse herbage we passed on to a carpet of fine green ver-
dure. I at first attributed this to some change in the nature
of the soil, but the inhabitants assured me that here, as
well as in Banda Oriental, where there is as great a differ-
ence between the country round Monte Video and the
thinly-inhabited savannahs of Colonia, the whole was to be
attributed to the manuring and grazing of the cattle. Ex-
actly the same fact has been observed in the prairies7 of
North America, where coarse grass, between five and six
feet high, when grazed by cattle, changes into common pas-
ture land. I am not botanist enough to say whether the
change here is owing to the introduction of new species,
to the altered growth of the same, or to a difference in their
proportional numbers. Azara has also observed with aston-
ishment this change: he is likewise much perplexed by the
immediate appearance of plants not occurring in the neigh-
bourhood, on the borders of any track that leads to a newly-
constructed hovel. In another part he says,8 " ces chevaux
(sauvages) ont la manie de preferer les chemins, et le bord
des routes pour deposer leurs excremens, dont on trouve des
monceaux dans ces endroits." Does this not partly explain
the circumstance? We thus have lines of richly manured
land serving as channels of communication across wide dis-
tricts.

Near the Guardia we find the southern limit of two Eu-
ropean plants, now become extraordinarily common. The
fennel in great profusion covers the ditch-banks in the neigh-
bourhood of Buenos Ayres, Monte Video, and other towns.
But the cardoon (Cynara cardunculus) has a far wider
range:9 it occurs in these latitudes on both sides of the

0 M. A. d'Orbigny (vol. i. p. 474) says that the cardoon and artichoke
are both found wild. Dr. Hooker (Botanical Magazine, vol. Iv. p. 2862),
has described a variety of the Cynara from this part of South America
under the name of incrmis. He states that botanists are now generally

Cordillera, across the continent. I saw it in unfrequented
spots in Chile, Entre Rios, and Banda Oriental. In the
latter country alone, very many (probably several hundred)
square miles are covered by one mass of these prickly plants,
and are impenetrable by man or beast. Over the undulating
plains, where these great beds occur, nothing else can now
live. Before their introduction, however, the surface must
have supported, as in other parts, a rank herbage. I doubt
whether any case is on record of an invasion on so grand
a scale of one plant over the aborigines. As I have already
said, I nowhere saw the cardoon south of the Salado; but
it is probable that in proportion as that country becomes
inhabited, the cardoon will extend its limits. The case is
different with the giant thistle (with variegated leaves) of
the Pampas, for I met with it in the valley of the Sauce.
According to the principles so well laid down by Mr. Lyell,
few countries have undergone more remarkable changes,
since the year 1535, when the first colonist of La Plata landed
with seventy-two horses. The countless herds of horses,
cattle, and sheep, not only have altered the whole aspect of
the vegetation, but they have almost banished the guanaco,
deer and ostrich. Numberless other changes must likewise
have taken place; the wild pig in some parts probably re-
places the peccari ; packs of wild dogs may be heard howling
on the wooded banks of the less-frequented streams; and
the common cat, altered into a large and fierce animal, in-
habits rocky hills. As M. d'Orbigny has remarked, the in-
crease in numbers of the carrion-vulture, since the introduc-
tion of the domestic animals, must have been infinitely great ;
and we have given reasons for believing that they have ex-
tended their southern range. No doubt many plants, besides
the cardoon and fennel, are naturalized; thus the islands
near the mouth of the Parana, are thickly clothed with
peach and orange trees, springing from seeds carried there
by the waters of the river.

agreed that the cardoon and the artichoke are varieties of one plant. I may
add, that an intelligent farmer assured me that he had observed in a deserted

which I have mentioned a few lines lower down, under the title of giant
thistle. Whether it is a true thistle I do not know; but it is quite different
from the cardoon; and more like a thistle properly so called.

THE VOYAGE OF THE BEAGLE 133

While changing horses at the Guardia several people ques-
tioned us much about the army, — I never saw anything like
the enthusiasm for Rosas, and for the success of the " most
just of all wars, because against barbarians." This expres-
sion, it must be confessed, is very natural, for till lately,
neither man, woman nor horse, was safe from the attacks
of the Indians. We had a long day's ride over the same
rich green plain, abounding with various flocks, and with
here and there a solitary estancia, and its one ombu tree.
In the evening it rained heavily: on arriving at a post-
house we were told by the owner, that if we had not a
regular passport we must pass on, for there were so
many robbers he would trust no one. When he read, how-
ever, my passport, which began with " El Naturalista Don
Carlos," his respect and civility were as unbounded as his
suspicions had been before. What a naturalist might be,
neither he nor his countrymen, I suspect, had any idea;
but probably my title lost nothing of its value from that
cause.

September 20th. — We arrived by the middle of the day at
Buenos Ayres. The outskirts of the city looked quite pretty,
with the agave hedges, and groves of olive, peach and willow
trees, all just throwing out their fresh green leaves. I rode
to the house of Mr. Lumb, an English merchant, to whose
kindness and hospitality, during my stay in the country, I
was greatly indebted.

The city of Buenos Ayres is large;10 and I should think
one of the most regular in the world. Every street is at right
angles to the one it crosses, and the parallel ones being equi-
distant, the houses are collected into solid squares of equal
dimensions, which are called quadras. On the other hand,
the houses themselves are hollow squares ; all the rooms open-
ing into a neat little courtyard. They are generally only
one story high, with flat roofs, which are fitted with seats,
and are much frequented by the inhabitants in summer. In
the centre of the town is the Plaza, where the public offices,
fortress, cathedral, etc., stand. Here also, the old viceroys,
before the revolution, had their palaces. The general assem-

or importance on the banks of the Plata, has 15,000.

blage of buildings possesses considerable architectural beauty,
although none individually can boast of any.

The great corral, where the animals are kept for slaugh-
ter to supply food to this beef-eating population, is one of
the spectacles best worth seeing. The strength of the horse
as compared to that of the bullock is quite astonishing: a
man on horseback having thrown his lazo round the horns
of a beast, can drag it anywhere he chooses. The animal
ploughing up the ground with outstretched legs, in vain
efforts to resist the force, generally dashes at full speed to
one side; but the horse immediately turning to receive the
shock, stands so firmly that the bullock is almost thrown
down, and it is surprising that their necks are not broken.
The struggle is not, however, one of fair strength; the
horse's girth being matched against the bullock's extended
neck. In a similar manner a man can hold the wildest horse,
if caught with the lazo, just behind the ears. When the
bullock has been dragged to the spot where it is to be
slaughtered, the matador with great caution cuts the ham-
strings. Then is given the death bellow; a noise more ex-
pressive of fierce agony than any I know. I have often dis-
tinguished it from a long distance, and have always known
that the struggle was then drawing to a close. The whole
sight is horrible and revolting : the ground is almost made of
bones ; and the horses and riders are drenched with gore.

2?th.—In the evening I set out on an
excursion to St. Fe, which is situated nearly three hun-
dred English miles from Buenos Ayres, on the banks of
the Parana. The roads in the neighbourhood of the city after
the rainy weather, were extraordinarily bad. I should never
have thought it possible for a bullock waggon to have
crawled along: as it was, they scarcely went at the rate of a
mile an hour, and a man was kept ahead, to survey the best
line for making the attempt. The bullocks were terribly
jaded: it is a great mistake to suppose that with improved
roads, and an accelerated rate of travelling, the sufferings of
the animals increase in the same proportion. We passed a
train of waggons and a troop of beasts on their road to
Mendoza. The distance is about 580 geographical miles, and
the journey is generally performed in fifty days. These
waggons are very long, narrow, and thatched with reeds;
they have only two wheels, the diameter of which in some
cases is as much as ten feet. Each is drawn by six bullocks,
which are urged on by a goad at least twenty feet long : this
is suspended from within the roof; for the wheel bullocks a
smaller one is kept; and for the intermediate pair, a point
projects at right angles from the middle of the long one.

The whole apparatus looked like some implement of war.

September 28th. — We passed the small town of Luxan,
where there is a wooden bridge over the river — a most unus-

ual convenience in this country. We passed also Areco.
The plains appeared level, but were not so in fact; for in
various places the horizon was distant. The estancias are
here wide apart; for there is little good pasture, owing- to
the land being covered by beds either of an acrid clover,
or of the great thistle. The latter, well known from the
animated description given by Sir F. Head, were at this
time of the year two- thirds grown; in some parts they were
as high as the horse's back, but in others they had not yet
sprung up, and the ground was bare and dusty as on a turn-
pike-road. The clumps were of the most brilliant green, and
they made a pleasing miniature-likeness of broken forest
land. When the thistles are full grown, the great beds are
impenetrable, except by a few tracts, as intricate as those
in a labyrinth. These are only known to the robbers, who
at this season inhabit them, and sally forth at night to rob
and cut throats with impunity. Upon asking at a house
whether robbers were numerous, I was answered, " The this-
tles are not up yet ;" — the meaning of which reply was not at
first very obvious. There is little interest in passing over
these tracts, for they are inhabited by few animals or birds,
excepting the bizcacha and its friend the little owl.

The bizcacha1 is well known to form a prominent feature
in the zoology of the Pampas. It is found as far south as
the Rio Negro, in lat. 41°, but not beyond. It cannot, like
the agouti, subsist on the gravelly and desert plains of Pata-
gonia, but prefers a clayey or sandy soil, which produces a
different and more abundant vegetation. Near Mendoza, at
the foot of the Cordillera, it occurs in close neighbourhood
with the allied alpine species. It is a very curious circum-
stance in its geographical distribution, that it has never been
seen, fortunately for the inhabitants of Banda Oriental, to
the eastward of the river Uruguay : yet in this province there
are plains which appear admirably adapted to its habits.
The Uruguay has formed an insuperable obstacle to its
migration: although the broader barrier of the Parana has
been passed, and the bizcacha is common in Entre Rios, the

*The bizcacha (Lagostomus trichodactylus) somewhat resembles a large
rabbit, but with bigger gnawing teeth and a long tail; it has, however, only
three toes behind, like the agouti. During the last three or four years the
•kins of these animals have been sent to England for the sake of the fur.

THE VOYAGE OF THE BEAGLE 137

province between these two great rivers. Near Buenos Ayres
these animals are exceedingly common. Their most favour-
ite resort appears to be those parts of the plain which during
one-half of the year are covered with giant thistles, to the
exclusion of other plants. The Gauchos affirm that it lives
on roots; which, from the great strength of its gnawing
teeth, and the kind of places frequented by it, seems probable.
In the evening the bizcachas come out in numbers, and quietly
sit at the mouths of their burrows on their haunches. At
such times they are very tame, and a man on horseback pass-
ing by seems only to present an object for their grave con-
templation. They run very awkwardly, and when running
out of danger, from their elevated tails and short front legs,
much resemble great rats. Their flesh, when cooked, is very
white and good, but it is seldom used.

The bizcacha has one very singular habit; namely, drag-
ging every hard object to the mouth of its burrow: around
each group of holes many bones of cattle, stones, thistle-
stalks, hard lumps of earth, dry dung, etc., are collected into
an irregular heap, which frequently amounts to as much as
a wheelbarrow would contain. I was credibly informed that
a gentleman, when riding on a dark night, dropped his
watch; he returned in the morning, and by searching the
neighbourhood of every bizcacha hole on the line of road,
as he expected, he soon found it. This habit of picking
up whatever may be lying on the ground anywhere near its
habitation, must cost much trouble. For what purpose it
is done, I am quite unable to form even the most remote
conjecture: it cannot be for defence, because the rubbish
is chiefly placed above the mouth of the burrow, which
enters the ground at a very small inclination. No doubt
there must exist some good reason; but the inhabitants of
the country are quite ignorant of it. The only fact which
I know analogous to it, is the habit of that extraordinary
Australian bird, the Calodera maculata, which makes an
elegant vaulted passage of twigs for playing in, and
which collects near the spot, land and sea-shells, bones,
and the feathers of birds, especially brightly coloured
ones. Mr. Gould, who has described these facts, informs
me, that the natives, when they lose any hard object,

138 CHARLES DARWIN

search the playing passages, and he has known a tobacco-
pipe thus recovered.

The little owl (Athene cunicularia), which has been so
often mentioned, on the plains of Buenos Ayres exclusively
inhabits the holes of the bizcacha; but in Banda Oriental it
is its own workman. During the open day, but more espe-
cially in the evening, these birds may be seen in every direc-
tion standing frequently by pairs on the hillock near their
burrows. If disturbed they either enter the hole, or, utter-
ing a shrill harsh cry, move with a remarkably undulatory
flight to a short distance, and then turning round, steadily
gaze at their pursuer. Occasionally in the evening they may
be heard hooting. I found in the stomachs of two which
I opened the remains of mice, and I one day saw a small
snake killed and carried away. It is said that snakes are
their common prey during the daytime. I may here men-
tion, as showing on what various kinds of food owls subsist,
that a species killed among the islets of the Chonos Archi-
pelago, had its stomach full of good-sized crabs. In India*
there is a fishing genus of owls, which likewise catches crabs.

In the evening we crossed the Rio Arrecife on a simple
raft made of barrels lashed together, and slept at the post-
house on the other side. I this day paid horse-hire for
thirty-one leagues; and although the sun was glaring hot I
was but little fatigued. When Captain Head talks of riding
fifty leagues a day, I do not imagine the distance is equal
to 150 English miles. At all events, the thirty-one leagues
was only 76 miles in a straight line, and in an open country
I should think four additional miles for turnings would be
a sufficient allowance.

2()th and joth. — We continued to ride over plains of the
same character. At San Nicolas I first saw the noble river
of the Parana. At the foot of the cliff on which the town
stands, some large vessels were at anchor. Before arriving
at Rozario, we crossed the Saladillo, a stream of fine clear
running water, but too saline to drink. Rozario is a large
town built on a dead level plain, which forms a cliff about
sixty feet high over the Parana. The river here is very
broad, with many islands, which are low and wooded, as is
"Journal of Asiatic Soc., vol. v. p. 363.

THE VOYAGE OF THE BEAGLE 139

also the opposite shore. The view would resemble that of a
great lake, if it were not for the linear-shaped islets, which
alone give the idea of running water. The cliffs are the most
picturesque part; sometimes they are absolutely perpendicu-
lar, and of a red colour; at other times in large broken
masses, covered with cacti and mimosa-trees. The real
grandeur, however, of an immense river like this, is derived
from reflecting how important a means of communication
and commerce it forms between one nation and another; to
what a distance it travels; and from how vast a territory
it drains the great body of fresh water which flows past
your feet.

For many leagues north and south of San Nicolas and
Rozario, the country is really level. Scarcely anything which
travellers have written about its extreme flatness, can be
considered as exaggeration. Yet I could never find a spot
where, by slowly turning round, objects were not seen at
greater distances in some directions than in others; and
this manifestly proves inequality in the plain. At sea, a
person's eye being six feet above the surface of the water,
his horizon is two miles and four-fifths distant. In like
manner, the more level the plain, the more nearly does the
horizon approach within these narrow limits; and this, in
my opinion, entirely destroys that grandeur which one would
have imagined that a vast level plain would have possessed.

October ist. — We started by moonlight and arrived at the
Rio Tercero by sunrise. The river is also called the Sala-
dillo, and it deserves the name, for the water is brackish.
I stayed here the greater part of the day, searching for fossil
bones. Besides a perfect tooth of the Toxodon, and many
scattered bones, I found two immense skeletons near each
other, projecting in bold relief from the perpendicular cliff
of the Parana. They were, however, so completely decayed,
that I could only bring away small fragments of one of the
great molar teeth ; but these are sufficient to show that the
remains belonged to a Mastodon, probably to the same spe-
cies with that, which formerly must have inhabited the Cor-
dillera in Upper Peru in such great numbers. The men
who took me in the canoe, said they had long known of these
skeletons, and had often wondered how they had got there:

140 CHARLES DARWIN

the necessity of a theory being felt, they came to the con-
clusion that, like the bizcacha, the mastodon was formerly
a burrowing animal ! In the evening we rode another stage,
and crossed the Monge, another brackish stream, bearing the
dregs of the washings of the Pampas.

October 2nd. — We passed through Corunda, which, from
the luxuriance of its gardens, was one of the prettiest vil-
lages I saw. From this point to St. Fe the road is not very
safe. The western side of the Parana northward, ceases to
be inhabited; and hence the Indians sometimes come down
thus far, and waylay travellers. The nature of the country
also favours this, for instead of a grassy plain, there is an
open woodland, composed of low prickly mimosas. We
passed some houses that had been ransacked and since de-
serted; we saw also a spectacle, which my guides viewed
with high satisfaction; it was the skeleton of an Indian
with the dried skin hanging on the bones, suspended to the
branch of a tree.

In the morning we arrived at St. Fe. I was surprised
to observe how great a change of climate a difference of only
three degrees of latitude between this place and Buenos
Ayres had caused. This was evident from the dress and
complexion of the men — from the increased size of the
ombu-trees — the number of new cacti and other plants —
and especially from the birds. In the course of an hour I
remarked half-a-dozen birds, which I had never seen at
Buenos Ayres. Considering that there is no natural bound-
ary between the two places, and that the character of the
country is nearly similar, the difference was much greater
than I should have expected.

October jrd and 4th. — I was confined for these two days
to my bed by a headache. A good-natured old womai\
who attended me, wished me to try many odd remedies. A
common practice is, to bind an orange-leaf or a bit of black
plaster to each temple: and a still more general plan is, to
split a bean into halves, moisten them, and place one on
each temple, where they will easily adhere. It is not thought
proper ever to remove the beans or plaster, but to allow
them to drop off; and sometimes, if a man, with patches on
his head, is asked, what is the matter? he will answer, "I

THE VOYAGE OF THE BEAGLE 141

had a headache the day before yesterday." Many of the
remedies used by the people of the country are ludicrously
strange, but too disgusting to be mentioned. One of the
least nasty is to kill and cut open two puppies and bind
them on each side of a broken limb. Little hairless dogs are
in great request to sleep at the feet of invalids.

St. Fe is a quiet little town, and is kept clean and in good
order. The governor, Lopez, was a common soldier at the
time of the revolution; but has now been seventeen years
in power. This stability of government is owing to his
tyrannical habits; for tyranny seems as yet better adapted
to these countries than republicanism. The governor's fa-
vourite occupation is hunting Indians: a short time since
he slaughtered forty-eight, and sold the children at the rate
of three or four pounds apiece.

October $th. — We crossed the Parana to St. Fe Bajada,
a town on the opposite shore. The passage took some hours,
as the river here consisted of a labyrinth of small streams,
separated by low wooded islands. I had a letter of intro-
duction to an old Catalonian Spaniard, who treated me with
the most uncommon hospitality. The Bajada is the capital
of Entre Rios. In 1825 the town contained 6000 inhabitants,
and the province 30,000; yet, few as the inhabitants are, no
province has suffered more from bloody and desperate revo-
lutions. They boast here of representatives, ministers, a
standing army, and governors : so it is no wonder that they
have their revolutions. At some future day this must be
one of the richest countries of La Plata. The soil is varied
and productive; and its almost insular form gives it two
grand lines of communication by the rivers Parana and
Uruguay.

I was delayed here five days, and employed myself in ex-
amining the geology of the surrounding country, which was
very interesting. We here see at the bottom of the cliffs,
beds containing sharks' teeth and sea-shells of extinct spe-
cies, passing above into an indurated marl, and from that
into the red clayey earth of the Pampas, with its calcareous
concretions and the bones of terrestrial quadrupeds. This
vertical section clearly tells us of a large bay of pure salt-

142 CHARLES DARWIN

water, gradually encroached on, and at last converted into
the bed of a muddy estuary, into which floating carcasses
were swept. At Punta Gorda, in Banda Oriental, I found
an alternation of the Pampsean estuary deposit, with a lime-
stone containing some of the same extinct sea-shells; and
this shows either a change in the former currents, or more
probably an oscillation of level in the bottom of the ancient
estuary. Until lately, my reasons for considering the Pam-
paean formation to be an estuary deposit were, its general
appearance, its position at the mouth of the existing great
river the Plata, and the presence of so many bones of ter-
restrial quadrupeds: but now Professor Ehrenberg has had
the kindness to examine for me a little of the red earth,
taken from low down in the deposit, close to the skeletons
of the mastodon, and he finds in it many infusoria, partly
salt-water and partly fresh-water forms, with the latter
rather preponderating; and therefore, as he remarks, the
water must have been brackish. M. A. d'Orbigny found on
the banks of the Parana, at the height of a hundred feet,
great beds of an estuary shell, now living a hundred miles
lower down nearer the sea; and I found similar shells at a
less height on the banks of the Uruguay; this shows that
just before the Pampas was slowly elevated into dry land,
the water covering it was brackish. Below Buenos Ayres
there are upraised beds of sea-shells of existing species,
which also proves that the period of elevation of the Pam-
pas was within the recent period.

In the Pampaean deposit at the Bajada I found the osse-
ous armour of a gigantic armadillo-like animal, the inside
of which, when the earth was removed, was like a great
cauldron; I found also teeth of the Toxodon and Mastodon,
and one tooth of a Horse, in the same stained and decayed
state. This latter tooth greatly interested me,* and I took
scrupulous care in ascertaining that it had been embedded
contemporaneously with the other remains; for I was not
then aware that amongst the fossils from Bahia Blanca
there was a horse's tooth hidden in the matrix: nor was it
then known with certainty that the remains of horses are

living in America at the time of Columbus.

common in North America. Mr. Lyell has lately brought
from the United States a tooth of a horse; and it is an in-
teresting fact, that Professor Owen could find in no species,
either fossil or recent, a slight but peculiar curvature char-
acterizing it, until he thought of comparing it with my speci-
men found here: he has named this American horse Equus
curvidens. Certainly it is a marvellous fact in the history
of the Mammalia, that in South America a native horse
should have lived and disappeared, to be succeeded in after-
ages by the countless herds descended from the few intro-
duced with the Spanish colonists!

The existence in South America of a fossil horse, of the
mastodon, possibly of an elephant,4 and of a hollow-horned
ruminant, discovered by MM. Lund and Clausen in the
caves of Brazil, are highly interesting facts with respect to
the geographical distribution of animals. At the present
time, if we divide America, not by the Isthmus of Panama,
but by the southern part of Mexico5 in lat. 20°, where the
great table-land presents an obstacle to the migration of
species, by affecting the climate, and by forming, with the
exception of some valleys and of a fringe of low land on
the coast, a broad barrier ; we shall then have the two zoo-
logical provinces of North and South America strongly con-
trasted with each other. Some few species alone have
passed the barrier, and may be considered as wanderers from
the south, such as the puma, opossum, kinkajou, and peccari.
South America is characterized by possessing many peculiar
gnawers, a family of monkeys, the llama, peccari, tapir,
opossums, and, especially, several genera of Edentata, the
order which includes the sloths, ant-eaters, and armadilloes.
North America, on the other hand, is characterized (putting
on one side a few wandering species) by numerous peculiar
gnawers, and by four genera (the ox, sheep, goat, and ante-

8tThis is the geographical division followed by Lichtenstein, Swainson,
Erichson, and Richardson. The section from Vera Cruz to Acapulco, given
by Humboldt in the Polit. Essay on Kingdom of N. Spain will show how
immense a barrier the Mexican table-land forms. Dr. Richardson, in his
admirable Report on the Zoology of N. America read before the Brit.
Assoc. 1836 (p. 157), talking of the identification of a Mexican animal
with the Synetheres prehensilis, says, " We do not know with what pro-
priety, but if correct, it is, if not a solitary instance, at least very nearly
so, of a rodent animal being common to North and South America."

lope) of hollow-horned ruminants, of which great division
South America is not known to possess a single species.
Formerly, but within the period when most of the now ex-
isting shells were living, North America possessed, besides
hollow-horned ruminants, the elephant, mastodon, horse, and
three genera of Edentata, namely, the Megatherium, Megal-
onyx, and Mylodon. Within nearly this same period (as
proved by the shells at Bahia Blanca) South America pos-
sessed, as we have just seen, a mastodon, horse, hollow-
horned ruminant, and the same three genera (as well as
several others) of the Edentata. Hence it is evident that
North and South America, in having within a late geo-
logical period these several genera in common, were much
more closely related in the character of their terrestrial in-
habitants than they now are. The more I reflect on this
case, the more interesting it appears: I know of no other
instance where we can almost mark the period and manner
of the splitting up of one great region into two well-char-
acterized zoological provinces. The geologist, who is fully
impressed with the vast oscillations of level which have
affected the earth's crust within late periods, will not fear
to speculate on the recent elevation of the Mexican plat-
form, or, more probably, on the recent submergence of land
in the West Indian Archipelago, as the cause of the present
zoological separation of North and South America. The
South American character of the West Indian mammals*
seems to indicate that this archipelago was formerly united
to the southern continent, and that it has subsequently been
an area of subsidence.

When America, and especially North America, possessed
its elephants, mastodons, horse, and hollow-horned rumi-
nants, it was much more closely related in its zoological
characters to the temperate parts of Europe and Asia than
it now is. As the remains of these genera are found on
both sides of Behring's Straits' and on the plains of Siberia,

•See Dr. Richards9n's Report, p. 157; also L'Institut, 1837, p. 253.
Cuvier says the kinkajou is found in the larger Antilles, but this is doubt-
ful. M. Gervais states that the Didelphis crancrivora is found there. It
is certain that the West Indies possess some mammifers peculiar to them-
selves. A tooth of a mastodon has been brought from Bahama; Edin. New
Phil. Journ., 1826, p. 395.

THE VOYAGE OF THE BEAGLE 145

we are led to look to the north-western side of North Amer-
ica as the former point of communication between the Old
and so-called New World. And as so many species, both
living and extinct, of these same genera inhabit and have
inhabited the Old World, it seems most probable that the
North American elephants, mastodons, horse, and hollow-
horned ruminants migrated, on land since submerged near
Behring's Straits, from Siberia into North America, and
thence, on land since submerged in the West Indies, into
South America, where for a time they mingled with the
forms characteristic of that southern continent, and have
since become extinct.

While travelling through the country, I received several
vivid descriptions of the effects of a late great drought; and
the account of this may throw some light on the cases where
vast numbers of animals of all kinds have been embedded
together. The period included between the years 1827 and
1830 is called the " gran seco," or the great drought. During
this time so little rain fell, that the vegetation, even to the
thistles, failed; the brooks were dried up, and the whole
country assumed the appearance of a dusty high road. This
was especially the case in the northern part of the province
of Buenos Ayres and the southern part of St. Fe. Very
great numbers of birds, wild animals, cattle, and horses
perished from the want of food and water. A man told me
that the deer8 used to come into his courtyard to the well,
which he had been obliged to dig to supply his own family
with water; and that the partridges had hardly strength to
fly away when pursued. The lowest estimation of the loss
of cattle in the province of Buenos Ayres alone, was taken
at one million head. A proprietor at San Pedro had pre-
viously to these years 20,000 cattle; at the end not one re-

8 In Captain Owen's Surveying Voyage (vol. ii. p. 274) there is a curious
account of the effects of a drought on the elephants, at Benguela (west
coast of Africa). " A number of these animals had some time since entered
the town, in a body, to possess themselves of the wells, not being able to
procure any water in the country. The inhabitants mustered, when a des-
perate conflict ensued, which terminated in the ultimate discomfiture of the
invaders, but not until they had killed one man. and wounded several
others." The town is said to have a population of nearly three thousand!
Dr. Malcolmson informs me that, during a great drought in India, the wild
animals entered the tents of some troops at Ellore, and that a hare drank
out of a vessel held by the adjutant of the regiment.

146 CHARLES DARWIN

mained. San Pedro is situated in the middle of the finest
country; and even now abounds again with animals; yet,
during the latter part of the " gran seco," live cattle were
brought in vessels for the consumption of the inhabitants.
The animals roamed from their estancias, and, wandering
far southward, were mingled together in such multitudes,
that a government commission was sent from Buenos Ayres
to settle the disputes of the owners. Sir Woodbine Parish
informed me of another and very curious source of dispute ;
the ground being so long dry, such quantities of dust were
blown about, that in this open country the landmarks be-
came obliterated, and people could not tell the limits of their
estates.

I was informed by an eye-witness that the cattle in herds
of thousands rushed into the Parana, and being exhausted
by hunger they were unable to crawl up the muddy banks,
and thus were drowned. The arm of the river which runs
by San Pedro was so full of putrid carcasses, that the master
of a vessel told me that the smell rendered it quite impass-
able. Without doubt several hundred thousand animals
thus perished in the river: their bodies when putrid were
seen floating down the stream; and many in all probability
were deposited in the estuary of the Plata. All the small
rivers became highly saline, and this caused the death of
vast numbers in particular spots ; for when an animal drinks
of such water it does not recover. Azara describes* the
fury of the wild horses on a similar occasion, rushing into
the marshes, those which arrived first being overwhelmed
and crushed by those which followed. He adds that more
than once he has seen the carcasses of upwards of a thou-
sand wild horses thus destroyed. I noticed that the smaller
streams in the Pampas were paved with a breccia of bones,
but this probably is the effect of a gradual increase, rather
than of the destruction at any one period. Subsequently
to the drought of 1827 to 1832, a very rainy season followed,
which caused great floods. Hence it is almost certain that
some thousands of the skeletons were buried by the deposits
of the very next year. What would be the opinion of a
geologist, viewing such an enormous collection of bones, of

9 Travels, vol. i. p. 374.

THE VOYAGE OF THE BEAGLE 147

all kinds of animals and of all ages, thus embedded in one
thick earthy mass? Would he not attribute it to a flood
having swept over the surface of the land, rather than to
the common order of things?10

October isth. — I had intended to push my excursion fur-
ther, but not being quite well, I was compelled to return by
a balandra, or one-masted vessel of about a hundred tons'
burden, which was bound to Buenos Ayres. As the weather
was not fair, we moored early in the day to a branch of a
tree on one of the islands. The Parana is full of islands,
which undergo a constant round of decay and renovation.
In the memory of the master several large ones had dis-
appeared, and others again had been formed and protected
by vegetation. They are composed of muddy sand, without
even the smallest pebble, and were then about four feet
above the level of the river ; but during the periodical floods
they are inundated. Th;y all present one character; numer-
ous willows and a few other trees are bound together by a
great variety of creeping plants, thus forming a thick jungle.
These thickets afford a retreat for capybaras and jaguars.
The fear of the latter animal quite destroyed all pleasure
in scrambling through the woods. This evening I had not
proceeded a hundred yards, before finding indubitable signs
of the recent presence of the tiger, I was obliged to come
back. On every island there were tracks; and as on the
former excursion " el rastro de los Indies " had been the
subject of conversation, so in this was " el rastro del tigre."

The wooded banks of the great rivers appear to be the
favourite haunts of the jaguar; but south of the Plata, I
was told that they frequented the reeds bordering lakes:
wherever they are, they seem to require water. Their com-
mon prey is the capybara, so that it is generally said, where
capybaras are numerous there is little danger from the
jaguar. Falconer states that near the southern side of the
mouth of the Plata there are many jaguars, and that they
chiefly live on fish ; this account I have heard repeated. On
the Parana they have killed many wood-cutters, and have

10 These droughts to & certain degree seem to be almost periodical; I was
told the dates of several others, and the intervals were about fifteen years.

148 CHARLES DARWIN

even entered vessels at night. There is a man now living
in the Bajada, who, coming up from below when it was
dark, was seized on the deck; he escaped, however, with
the loss of the use of one arm. When the floods drive these
animals from the islands, they are most dangerous. I was
told that a few years since a very large one found its way
into a church at St. Fe: two padres entering one after the
other were killed, and a third, who came to see what was the
matter, escaped with difficulty. The beast was destroyed by
being shot from a corner of the building which was un-
roofed. They commit also at these times great ravages
among cattle and horses. It is said that they kill their prey
by breaking their necks. If driven from the carcass, they
seldom return to it. The Gauchos say that the jaguar, when
wandering about at night, is much tormented by the foxes
yelping as they follow him. This is a curious coincidence
with the fact which is generally affirmed of the jackals ac-
companying, in a similarly officious manner, the East Indian
tiger. The jaguar is a noisy animal, roaring much by night,
and especially before bad weather.

One day, when hunting on the banks of the Uruguay, I
was shown certain trees, to which these animals constantly
recur for the purpose, as it is said, of sharpening their
claws. I saw three well-known trees; in front, the bark
was worn smooth, as if by the breast of the animal, and on
each side there were deep scratches, or rather grooves, ex-
tending in an oblique line, nearly a yard in length. The
scars were of different ages. A common method of as-
certaining whether a jaguar is in the neighbourhood is to
examine these trees. I imagine this habit of the jaguar is
exactly similar to one which may any day be seen in the
common cat, as with outstretched legs and exserted claws it
scrapes the leg of a chair ; and I have heard of young fruit-
trees in an orchard in England having been thus much in-
jured. Some such habit must also be common to the puma,
for on the bare hard soil of Patagonia I have frequently
seen scores so deep that no other animal could have made
them. The object of this practice is, I believe, to tear off
the ragged points of their claws, and not, as the Gauchos
think, to sharpen them. The jaguar is killed, without much

THE VOYAGE OF THE BEAGLE 149

difficulty, by the aid of dogs baying and driving him up a
tree, where he is despatched with bullets.

Owing to bad weather we remained two days at our moor-
ings. Our only amusement was catching fish for our dinner :
there were several kinds, and all good eating. A fish called
the "armado" (a Silurus) is remarkable from a harsh grat-
ing noise which it makes when caught by hook and line,
and which can be distinctly heard when the fish is beneath
the water. This same fish has the power of firmly catching
hold of any object, such as the blade of an oar or the fishing-
line, with the strong spine both of its pectoral and dorsal
fin. In the evening the weather was quite tropical, the
thermometer standing at 79°. Numbers of fireflies were
hovering about, and the musquitoes were very troublesome.
I exposed my hand for five minutes, and it was soon black
with them ; I do not suppose there could have been less than
fifty, all busy sucking.

October i^th. — We got under way and passed Punta
Gorda, where there is a colony of tame Indians from the
province of Missiones. We sailed rapidly down the current,
but before sunset, from a silly fear of bad weather, we
brought-to in a narrow arm of the river. I took the boat
and rowed some distance up this creek. It was very narrow,
winding, and deep; on each side a wall thirty or forty feet
high, formed by trees intwined with creepers, gave to the
canal a singularly gloomy appearance. I here saw a very
extraordinary bird, called the Scissor-beak (Rhynchops
nigra). It has short legs, web feet, extremely long-pointed
wings, and is of about the size of a tern. The beak is flat-
tened laterally, that is, in a plane at right angles to that
of a spoonbill or duck. It is as flat and elastic as an ivory
paper-cutter, and the lower mandible, differing from every
other bird, is an inch and a half longer than the upper. In
a lake near Maldonado, from which the water had been
nearly drained, and which, in consequence, swarmed with
small fry, I saw several of these birds, generally in small
flocks, flying rapidly backwards and forwards close to the >
surface of the lake. They kept their bills wide open, and
the lower mandible half buried in the water. Thus skimming
the surface, they ploughed it in their course : the water was

150 CHARLES DARWIN

quite smooth, and it formed a most curious spectacle to be-
hold a flock, each bird leaving its narrow wake on the mir-
ror-like surface. In their flight they frequently twist about
with extreme quickness, and dexterously manage with their
projecting lower mandible to plough up small fish, which are
secured by the upper and shorter half of their scissor-like

bills. This fact I repeatedly saw, as, like swallows, they
continued to fly backwards and forwards close before me.
Occasionally when leaving the surface of the water their
flight was wild, irregular, and rapid; they then uttered loud
harsh cries. When these birds are fishing, the advantage
of the long primary feathers of their wings, in keeping them
dry, is very evident. When thus employed, their forms re-
semble the symbol by which many artists represent marine
birds. Their tails are much used in steering their irregular
course.

These birds are common far inland along the course of
the Rio Parana ; it is said that they remain here during the
whole year, and breed in the marshes. During the day they
rest in liocks on the grassy plains at some distance from
the water. Being at anchor, as I have said, in one of the
deep creeks between the islands of the Parana, as the even-
ing drew to a close, one of these scissor-beaks suddenly ap-
peared. The water was quite still, and many little fish were
rising. The bird continued for a long time to skim the
surface, flying in its wild and irregular manner up and down
the narrow canal, now dark with the growing night and the
shadows of the overhanging trees. At Monte Video, I ob-
served that some large flocks during the day remained on the
mud-banks at the head of the harbour, in the same manner
as on the grassy plains near the Parana; and every even-

THE VOYAGE OF THE BEAGLE 151

ing they took flight seaward. From these facts I suspect
that the Rhynchops generally fishes by night, at which time
many of the lower animals come most abundantly to the
surface. M. Lesson states that he has seen these birds
opening the shells of the mactrse buried in the sand-banks on
the coast of Chile: from their weak bills, with the lower
mandible so much projecting, their short legs and long
wings, it is very improbable that this can be a general habit.
In our course down the Parana, I observed only three
other birds, whose habits are worth mentioning. One is a
small kingfisher (Ceryle Americana) ; it has a longer tail
than the European species, and hence does not sit in so stiff
and upright a position. Its flight also, instead of being di-
rect and rapid, like the course of an arrow, is weak and
undulatory, as among the soft-billed birds. It utters a low
note, like the clicking together of two small stones. A small
green parrot (Conurus murinus), with a grey breast, ap-
pears to prefer the tall trees on the islands to any other
situation for its building-place. A number of nests are
placed so close together as to form one great mass of sticks.
These parrots always live in flocks, and commit great ravages
on the corn-fields. I was told, that near Colonia 2500 were
killed in the course of one year. A bird with a forked tail,
terminated by two long feathers (Tyrannus savana), and
named by the Spaniards scissor-tail, is very common near
Buenos Ayres: it commonly sits on a branch of the ontbu
tree, near a house, and thence takes a short flight in pursuit
of insects, and returns to the same spot. When on the wing
it presents in its manner of flight and general appearance
a caricature-likeness of the common swallow. It has the
power of turning very shortly in the air, and in so doing
opens and shuts its tail, sometimes in a horizontal or lateral
and sometimes in a vertical direction, just like a pair of
scissors.

October i6th. — Some leagues below Rozario, the western
shore of the Parana is bounded by perpendicular cliffs,
which extend in a long line to below San Nicolas; hence it

1 more resembles a sea-coast than that of a fresh-water river.

'it is a great drawback to the scenery of the Parana, that,
from the soft nature of its banks, the water is very muddy.

152 CHARLES DARWIN

The Uruguay, flowing through a granitic country, is much
clearer; and where the two channels unite at the head of
the Plata, the waters may for a long distance be distin-
guished by their black and red colours. In the evening, the
wind being not quite fair, as usual we immediately moored,
and the next day, as it blew rather freshly, though with a
favouring current, the master was much too indolent to think
of starting. At Bajada, he was described to me as " hombre
muy aflicto " — a man always miserable to get on ; but cer-
tainly he bore all delays with admirable resignation. He
was an old Spaniard, and had been many years in this
country. He professed a great liking to the English, but
stoutly maintained that the battle of Trafalgar was merely
won by the Spanish captains having been all bought over;
and that the only really gallant action on either side was
performed by the Spanish admiral. It struck me as rather
characteristic, that this man should prefer his countrymen
being thought the worst of traitors, rather than unskilful or
cowardly.

i8th and ipth. — We continued slowly to sail down the
noble stream: the current helped us but little. We met,
during our descent, very few vessels. One of the best gifts
of nature, in so grand a channel of communication, seems
here wilfully thrown away — a river in which ships might
navigate from a temperate country, as surprisingly abundant
in certain productions as destitute of others, to another pos-
sessing a tropical climate, and a soil which, according to
the best of judges, M. Bonpland, is perhaps unequalled in
fertility in any part of the world. How different would
have been the aspect of this river if English colonists had
by good fortune first sailed up the Plata ! What noble towns
would now have occupied its shores ! Till the death of
Francia, the Dictator of Paraguay, these two countries must
remain distinct, as if placed on opposite sides of the globe.
And when the old bloody-minded tyrant is gone to his long
account, Paraguay will be torn by revolutions, violent in
proportion to the previous unnatural calm. That country
will have to learn, like every other South American state,
that a republic cannot succeed till it contains a certain body
of men imbued with the principles of justice and honour.

THE VOYAGE OF THE BEAGLE 153

October 20th. — Being arrived at the mouth of the Parana,
and as I was very anxious to reach Buenos Ayres, I went
on shore at Las Conchas, with the intention of riding there.
Upon landing, I found to my great surprise that I was to
a certain degree a prisoner. A violent revolution having
broken out, all the ports were laid under an embargo. I
could not return to my vessel, and as for going by land to
the city, it was out of the question. After a long conversa-
tion with the commandant, I obtained permission to go the
next day to General Rolor, who commanded a division of
the rebels on this side the capital. In the morning I rode
to the encampment. The general, officers, and soldiers, all
appeared, and I believe really were, great villains. The
general, the very evening before he left the city, voluntarily
went to the Governor, and with his hand to his heart, pledged
his word of honour that he at least would remain faithful
to the last. The general told me that the city was in a state
of close blockade, and that all he could do was to give me
a passport to the commander-in-chief of the rebels at Quil-
mes. We had therefore to take a great sweep round the
city, and it was with much difficulty that we procured horses.
My reception at the encampment was quite civil, but I was
told it was impossible that I could be allowed to enter the
city. I was very anxious about this, as I anticipated the
Beagle's departure from the Rio Plata earlier than it took
place. Having mentioned, however, General Rosas's oblig-
ing kindness to me when at the Colorado, magic itself could
not have altered circumstances quicker than did this con-
versation. I was instantly told that though they could not
give me a passport, if I chose to leave my guide and horses,
I might pass their sentinels. I was too glad to accept of
this, and an officer was sent with me to give directions that
I should not be stopped at the bridge. The road for the
space of a league was quite deserted. I met one party of
soldiers, who were satisfied by gravely looking at an old
passport : and at length I was not a little pleased to find my-
self within the city.

This revolution was supported by scarcely any pretext of
grievances : but in a state which, in the course of nine months
(from February to October, 1820), underwent fifteen

154 CHARLES DARWIN

changes in its government — each governor, according to the
constitution, being elected for three years — it would be very
unreasonable to ask for pretexts. In this case, a party of
men — who, being attached to Rosas, were disgusted with
the governor Balcarce — to the number of seventy left the
city, and with the cry of Rosas the whole country took arms.
The city was then blockaded, no provisions, cattle or horses,
were allowed to enter; besides this, there was only a little
skirmishing, and a few men daily killed. The outside party
tvell knew that by stopping the supply of meat they would
certainly be victorious. General Rosas could not have known
of this rising ; but it appears to be quite consonant with the
plans of his party. A year ago he was elected governor, but
he refused it, unless the Sala would also confer on him
extraordinary powers. This was refused, and since then
his party have shown that no other governor can keep his
place. The warfare on both sides was avowedly protracted
till it was possible to hear from Rosas. A note arrived a
few days after I left Buenos Ayres, which stated that the
General disapproved of peace having been broken, but that
he thought the outside party had justice on their side. On
the bare reception of this, the Governor, ministers, and part
of the military, to the number of some hundreds, fled from
the city. The rebels entered, elected a new governor, and
were paid for their services to the number of 5500 men.
From these proceedings, it was clear that Rosas ultimately
would become the dictator: to the term king, the people in
this, as in other republics, have a particular dislike. Since
leaving South America, we have heard that Rosas has
been elected, with powers and for a time altogether opposed
to the constitutional principles of the republic.

HAVING been delayed for nearly a fortnight in the
city, I was glad to escape on board a packet bound
for Monte Video. A town in a state of blockade
must always be a disagreeable place of residence ; in this case
moreover there were constant apprehensions from robbers
within. The sentinels were the worst of all; for, from
their office and from having arms in their hands, they robbed
with a degree of authority which other men could not
imitate.

Our passage was a very long and tedious one. The Plata
looks like a noble estuary on the map ; but is in truth a poor
affair. A wide expanse of muddy water has neither gran-
deur nor beauty. At one time of the day, the two shores,
both of which are extremely low, could just be distinguished
from the deck. On arriving at Monte Video I found that
the Beagle would not sail for some time, so I prepared for a
short excursion in this part of Banda Oriental. Everything
which I have said about the country near Maldonado is ap-
plicable to Monte Video; but the land, with the one excep-
tion of the Green Mount 450 feet high, from which it takes
its name, is far more level. Very little of the undulating
grassy plain is enclosed; but near the town there are a few
hedge-banks, covered with agaves, cacti, and fennel.

November i^ih. — We left Monte Video in the afternoon.

155

156 CHARLES DARWIN

I intended to proceed to Colonia del Sacramiento, situated
on the northern bank of the Plata and opposite to Buenos
Ayres, and thence, following up the Uruguay, to the village
of Mercedes on the Rio Negro (one of the many rivers of
this name in South America), and from this point to return
direct to Monte Video. We slept at the house of my guide
at Canelones. In the morning we rose early, in the hopes
of being able to ride a good distance; but it was a vain at-
tempt, for all the rivers were flooded. We passed in boats
the streams of Canelones, St. Lucia, and San Jose, and thus
lost much time. On a former excursion I crossed the Lucia
near its mouth, and I was surprised to observe how easily
our horses, although not used to swim, passed over a width
of at least six hundred yards. On mentioning this at Monte
Video, I was told that a vessel containing some mounte-
banks and their horses, being wrecked in the Plata, one horse
swam seven miles to the shore. In trie course of the day I
was amused by the dexterity with which a Gaucho forced
a restive horse to swim a river. He stripped off his clothes,
and jumping on its back, rode into the water till it was out
of its depth; then slipping off over the crupper, he caught
hold of the tail, and as often as the horse turned round,
the man frightened it back by splashing water in its face.
As soon as the horse touched the bottom on the other side,
the man pulled himself on, and was firmly seated, bridle
in hand, before the horse gained the bank. A naked man
on a naked horse is a fine spectacle; I had no idea how well
the two animals suited each other. The tail of a horse is a
very useful appendage ; I have passed a river in a boat with
four people in it, which was ferried across in the same way
as the Gaucho. If a man and horse have to cross a broad
river, the best plan is for the man to catch hold of the pom-
mel or mane, and help himself with the other arm.

We slept and stayed the following day at the post of
Cufre. In the evening the postman or letter-carrier arrived.
He was a day after his time, owing to the Rio Rozario being
flooded. It would not, however, be of much consequence;
for, although he had passed through some of the principal
towns in Banda Oriental, his luggage consisted of two let-
ters ! The view from the house was pleasing ; an undulating

THE VOYAGE OF THE BEAGLE 157

green surface, with distant glimpses of the Plata. I find
that I look at this province with very different eyes from
what I did upon my first arrival. I recollect I then thought
it singularly level; but now, after galloping over the Pam-
pas, my only surprise is, what could have induced me ever
to call it level. The country is a series of undulations, in
themselves perhaps not absolutely great, but, as compared
to the plains of St. Fe, real mountains. From these in-
equalities there is an abundance of small rivulets, and the
turf is green and luxuriant.

November i"jih. — We crossed the Rozario, which was
deep and rapid, and passing the village of Colla, arrived
at midday at Colonia del Sacramiento. The distance is
twenty leagues, through a country covered with fine grass,
but poorly stocked with cattle or inhabitants. I was in-
vited to sleep at Colonia, and to accompany on the follow-
ing day a gentleman to his estancia, where there were some
limestone rocks. The town is built on a stony promontory
something in the same manner as at Monte Video. It is
strongly fortified, but both fortifications and town suffered
much in the Brazilian war. It is very ancient; and the
irregularity of the streets, and the surrounding groves of
old orange and peach trees, gave it a pretty appearance.
The church is a curious ruin; it was used as a powder-
magazine, and was struck by lightning in one of the ten
thousand thunder-storms of the Rio Plata. Two-thirds of
the building were blown away to the very foundation; and
the rest stands a shattered and curious monument of the
united powers of lightning and gunpowder. In the evening
I wandered about the half-demolished walls of the town. It
was the chief seat of the Brazilian war ; — a war most in-
jurious to this country, not so much in its immediate effects,
as in being the origin of a multitude of generals and all
other grades of officers. More generals are numbered (but
| not paid) in the United Provinces of La Plata than in the
United Kingdom of Great Britain. These gentlemen have
learned to like power, and do not object to a little skirmish-
ing. Hence there are many always on the watch to create
disturbance and to overturn a government which as yet
has never rested on any staple foundation. I noticed, how-

158 CHARLES DARWIN

ever, both here and in other places, a very general interest
in the ensuing election for the President; and this appears
a good sign for the prosperity of this little country. The
inhabitants do not require much education in their repre-
sentatives; I heard some men discussing the merits of those
for Colonia ; and it was said that, " although they were not
men of business, they could all sign their names:" with this
they seemed to think every reasonable man ought to be
satisfied.

i8th. — Rode with my host to his estancia, at the Arroyo
de San Juan. In the evening we took a ride round the
estate: it contained two square leagues and a half, and was
situated in what is called a rincon; that is, one side was
fronted by the Plata, and the two others guarded by im-
passable brooks. There was an excellent port for little ves-
sels, and an abundance of small wood, which is valuable
as supplying fuel to Buenos Ayres. I was curious to know
the value of so complete an estancia. Of cattle there were
3000, and it would well support three or four times that
number; of mares 800, together with 150 broken-in horses,
and 600 sheep. There was plenty of water and limestone,
a rough house, excellent corrals, and a peach orchard. For
all this he had been offered £2000, and he only wanted £500
additional, and probably would sell it for less. The chief
trouble with an estancia is driving the cattle twice a week
to a central spot, in order to make them tame, and to count
them. • This latter operation would be thought difficult,
where there are ten or fifteen thousand head together. It
is managed on the principle that the cattle invariably di-
vide themselves into little troops of from forty to one hun-
dred. Each troop is recognized by a few peculiarly marked
animals, and its number is known: so that, one being lost
out of ten thousand, it is perceived by its absence from one
of the tropillas. During a stormy night the cattle all mingle
together; but the next morning the tropillas separate as
before ; so that each animal must know its fellow out of ten
thousand others.

On two occasions I met with in this province some oxen
of a very curious breed, called nata or niata. They appear
externally to hold nearly the same relation to other cattle,

THE VOYAGE OF THE BEAGLE 159

which bull or pug dogs do to other dogs. Their forehead
is very short and broad, with the nasal end turned up, and
the upper lip much drawn back; their lower jaws project
beyond the upper, and have a corresponding upward curve ;
hence their teeth are always exposed. Their nostrils are
seated high up and are very open; their eyes project out-
wards. When walking they carry their heads low, on a short
neck; and their hinder legs are rather longer compared
with the front legs than is usual. Their bare teeth, their
short heads, and upturned nostrils give them the most ludi-
crous self-confident air of defiance imaginable.

Since my return, I have procured a skeleton head,
through the kindness of my friend Captain Sulivan, R. N.,
which is now deposited in the College of Surgeons.1 Don
F. Muniz, of Luxan, has kindly collected for me all the in-
formation which he could respecting this breed. From his
account it seems that about eighty or ninety years ago, they
were rare and kept as curiosities at Buenos Ayres. The
breed is universally believed to have originated amongst
the Indians southward of the Plata; and that it was with
them the commonest kind. Even to this day, those reared
in the provinces near the Plata show their less civilized
origin, in being fiercer than common cattle, and in the cow
easily deserting her first calf, if visited too often or mo-
lested. It is a singular fact that an almost similar structure
to the abnormal2 one of the niata breed, characterizes, as I
am informed by Dr. Falconer, that great extinct ruminant
of India, the Sivatherium. The breed is very true; and a
niata bull and cow invariably produce niata calves. A niata
bull with a common cow, or the reverse cross, produces off-
spring having an intermediate character, but with the niata
characters strongly displayed: according to Senor Muniz,
there is the clearest evidence, contrary to the common belief
of agriculturists in analogous cases, that the niata cow when
crossed with a common bull transmits her peculiarities more
strongly than the niata bull when crossed with a common

I hope he will publish in some Journal.

cow. When the pasture is tolerably long, the niata cattle
feed with the tongue and palate as well as common cattle;
but during the great droughts, when so many animals per-
ish, the niata breed is under a great disadvantage, and would
be exterminated if not attended to; for the common cattle,
like horses, are able just to keep alive, by browsing with
their lips on twigs of trees and reeds; this the niatas cannot
so well do, as their lips do not join, and hence they are found
to perish before the common cattle. This strikes me as a
good illustration of how little we are able to judge from the
ordinary habits of life, on what circumstances, occurring
only at long intervals, the rarity or extinction of a species
may be determined.

November ipth. — Passing the valley of Las Vacas, we
slept at a house of a North American, who worked a lime-
kiln on the Arroyo de las Vivoras. In the morning we rode
to a projecting headland on the banks of the river, called
Punta Gorda. On the way we tried to find a jaguar. There
were plenty of fresh tracks, and we visited the trees, on
which they are said to sharpen their claws; but we did not
succeed in disturbing one. From this point the Rio Uru-
guay presented to our view a noble volume of water. From
the clearness and rapidity of the stream, its appearance was
far superior to that of its neighbour the Parana. On the
opposite coast, several branches from the latter river entered
the Uruguay. As the sun was shining, the two colours of
the waters could be seen quite distinct.

In the evening we proceeded on our road towards Mer-
cedes on the Rio Negro. At night we asked permission to
sleep at an estancia at which we happened to arrive. It was
a very large estate, being ten leagues square, and the owner
is one of the greatest landowners in the country. His neph-
ew had charge of it, and with him there was a captain in
the army, who the other day ran away from Buenos Ayres.
Considering their station, their conversation was rather
amusing. They expressed, as was usual, unbounded astonish-
ment at the globe being round, and could scarcely credit
that a hole would, if deep enough, come out on the other
side. They had, however, heard of a country where there
were six months of light and six of darkness, and where

THE VOYAGE OF THE BEAGLE 161

the inhabitants were very tall and thin ! They were curious
about the price and condition of horses and cattle in Eng-
land. Upon finding out we did not catch our animals with
the lazo, they cried out, "Ah, then, you use nothing but
the bolas:" the idea of an enclosed country was quite new
to them. The captain at last said, he had one question to
ask me, which he should be very much obliged if I would
answer with all truth. I trembled to think how deeply sci-
entific it would be: it was, "Whether the ladies of Buenos
Ayres were not the handsomest in the world." I replied, like
a renegade, " Charmingly so." He added, " I have one other
question: Do ladies in any other part of the world wear
such large combs ? " I solemnly assured him that they did
not. They were absolutely delighted. The captain ex-
claimed, " Look there ! a man who has seen half the world
says it is the case ; we always thought so, but now we know
it." My excellent judgment in combs and beauty procured
me a most hospitable reception; the captain forced me to
take his bed, and he would sleep on his recado.

21 st. — Started at sunrise, and rode slowly during the
whole day. The geological nature of this part of the prov-
ince was different from the rest, and closely resembled that
of the Pampas. In consequence, there were immense beds
of the thistle, as well as of the cardoon: the whole country,
indeed, may be called one great bed of these plants. The
two sorts grow separate, each plant in company with its
own kind. The cardoon is as high as a horse's back, but the
Pampas thistle is often higher than the crown of the rider's
head. To leave the road for a yard is out of the question;
and the road itself is partly, and in some cases entirely
closed. Pasture, of course there is none; if cattle or horses
once enter the bed, they are for the time completely lost.
Hence it is very hazardous to attempt to drive cattle at
this season of the year; for when jaded enough to face the
thistles, they rush among them, and are seen no more. In
these districts there are very few estancias, and these few
are situated in the neighbourhood of damp valleys, where
fortunately neither of these overwhelming plants can exist.
As night came on before we arrived at our journey's end,
we slept at a miserable little hovel inhabited by the poorest
VOL. xxix — F HC

162 CHARLES DARWIN

people. The extreme though rather formal courtesy of our
host and hostess, considering their grade of life, was quite
delightful.

November 22nd, — Arrived at an estancia on the Berquelo
belonging to a very hospitable Englishman, to whom I had
a letter of introduction from my friend Mr. Lumb. I stayed
here three days. One morning I rode with my host to the
Sierra del Pedro Flaco, about twenty miles up the Rio
Negro. Nearly the whole country was covered with good
though coarse grass, which was as high as a horse's belly;
yet there were square leagues without a single head of cattle.
The province of Banda Oriental, if well stocked, would sup-
port an astonishing number of animals; at present the an-
nual export of hides from Monte Video amounts to three
hundred thousand; and the home consumption, from waste,
is very considerable. An " estanciero " told me that he often
had to send large herds of cattle a long journey to a salting
establishment, and that the tired beasts were frequently
obliged to be killed and skinned; but that he could never
persuade the Gauchos to eat of them, and every evening
a fresh beast was slaughtered for their suppers ! The view
of the Rio Negro from the Sierra was more picturesque than
any other which I saw in this province. The river, broad,
deep, and rapid, wound at the foot of a rocky precipitous
cliff: a belt of wood followed its course, and the horizon
terminated in the distant undulations of the turf-plain.

When in this neighbourhood, I several times heard of
the Sierra de las Cuentas: a hill distant many miles to the
northward. The name signifies hill of beads. I was assured
that vast numbers of little round stones, of various colours,
each with a small cylindrical hole, are found there. For-
merly the Indians used to collect them, for the purpose of
making necklaces and bracelets — a taste, I may observe,
which is common to all savage nations, as well as to the most
polished. I did not know what to understand from this
story, but upon mentioning it at the Cape of Good Hope
to Dr. Andrew Smith, he told me that he recollected find-
ing on the south-eastern coast of Africa, about one hundred
miles to the eastward of St. John's river, some quartz crys-
tals with their edges blunted from attrition, and mixed with

THE VOYAGE OF THE BEAGLE 163

gravel on the sea-beach. Each crystal was about five lines
in diameter, and from an inch to an inch and a half in
length. Many of them had a small canal extending from
one extremity to the other, perfectly cylindrical, and of a
size that readily admitted a coarse thread or a piece of fine
catgut. Their colour was red or dull white. The natives
were acquainted with this structure in crystals. I have
mentioned these circumstances because, although no crystal-
lized body is at present known to assume this form, it may
lead some future traveller to investigate the real nature of
such stones.

While staying at this estancia, I was amused with what
I saw and heard of the shepherd-dogs of the country.3 When
riding, it is a common thing to meet a large flock of sheep
guarded by one or two dogs, at the distance of some miles
from any house or man. I often wondered how so firm a
friendship had been established. The method of education
consists in separating the puppy, while very young, from
the bitch, and in accustoming it to its future companions.
An ewe is held three or four times a day for the little thing
to suck, and a nest of wool is made for it in the sheep-pen ;
at no time is it allowed to associate with other dogs, or with
the children of the family. The puppy is, moreover, gen-
erally castrated; so that, when grown up, it can scarcely
have any feelings in common with the rest of its kind. From
this education it has no wish to leave the flock, and just
as another dog will defend its master, man, so will these
the sheep. It is amusing to observe, when approaching a
flock, how the dog immediately advances barking, and the
sheep all close in his rear, as if round the oldest ram. These
dogs are also easily taught to bring home the flock, at a
certain hour in the evening. Their most troublesome fault,
when young, is their desire of playing with the sheep; for
in their sport they sometimes gallop their poor subjects most
unmercifully.

The shepherd-dog comes to the house every day for some
meat, and as soon as it is given him, he skulks away as if

3 M. A. d'Orbigny has given nearly a similar account of these dogs,
torn. i. p. 175.

164 CHARLES DARWIN

ashamed of himself. On these occasions the house-dogs are
very tyrannical, and the least of them will attack and pursue
the stranger. The minute, however, the latter has reached
the flock, he turns round and begins to bark, and then all
the house-dogs take very quickly to their heels. In a similar
manner a whole pack of the hungry wild dogs will scarcely
ever (and I was told by some never) venture to attack a
flock guarded by even one of these faithful shepherds. The
whole account appears to me a curious instance of the plia-
bility of the affections in the dog; and yet, whether wild or
however educated, he has a feeling of respect or fear for
those that are fulfilling their instinct of association. For
we can understand on no principle the wild dogs being
driven away by the single one with its flock, except that they
consider, from some confused notion, that the one thus asso-
ciated gains power, as if in company with its own kind.
F. Cuvier has observed, that all animals that readily enter
into domestication, consider man as a member of their own
society, and thus fulfil their instinct of association. In
the above case the shepherd-dog ranks the sheep as its fel-
low-brethren, and thus gains confidence; and the wild dogs,
though knowing that the individual sheep are not dogs, but
are good to eat, yet partly consent to this view when seeing
them in a flock with a shepherd-dog at their head.

One evening a " domidor " (a subduer of horses) came
for the purpose of breaking-in some colts. I will describe
the preparatory steps, for I believe they have not been men-
tioned by other travellers. A troop of wild young horses
is driven into the corral, or large enclosure of stakes, and
the door is shut. We will suppose that one man alone has
to catch and mount a horse, which as yet had never felt
bridle or saddle. I conceive, except by a Gaucho, such a feat
would be utterly impracticable. The Gaucho picks out a
full-grown colt; and as the beast rushes round the circus,
he throws his lazo so as to catch both the front legs. In-
stantly the horse rolls over with a heavy shock, and whilst
struggling on the ground, the Gaucho, holding the lazo
tight, makes a circle, so as to catch one of the hind legs,
just beneath the fetlock, and draws it close to the two front
legs: he then hitches the lazo, so that the three are bound

THE VOYAGE OF THE BEAGLE 165

together. Then sitting on the horse's neck, he fixes a strong
bridle, without a bit, to the lower jaw: this he does by pass-
ing a narrow thong through the eye-holes at the end of the
reins, and several times round both jaw and tongue. The
two front legs are now tied closely together with a strong
leathern thong, fastened by a slip-knot. The lazo, which
bound the three together, being then loosed, the horse rises
with difficulty. The Gaucho now holding fast the bridle
fixed to the lower jaw, leads the horse outside the corral. If
a second man is present (otherwise the trouble is much
greater) he holds the animal's head, whilst the first puts on
the horsecloths and saddle, and girths the whole tog-ether.
During this operation, the horse, from dread and astonish-
ment at thus being bound round the waist, throws himself
over and over again on the ground, and, till beaten, is un-
willing to rise. At last, when the saddling is finished, the
poor animal can hardly breathe from fear, and is white with
foam and sweat. The man now prepares to mount by press-
ing heavily on the stirrup, so that the horse may not lose
its balance ; and at the moment that he throws his leg over
the animal's back, he pulls the slip-knot binding the front
legs, and the beast is free. Some " domidors " pull the knot
while the animal is lying on the ground, and, standing over
the saddle, allow him to rise beneath them. The horse, wild
with dread, gives a few most violent bounds, and then starts
off at full gallop: when quite exhausted, the man, by pa-
tience, brings him back to the corral, where, reeking hot and
scarcely alive, the poor beast is let free. Those animals
which will not gallop away, but obstinately throw themselves
on the ground, are by far the most troublesome. This process
is tremendously severe, but in two or three trials the horse
is tamed. It is not, however, for some weeks that the animal
is ridden with the iron bit and solid ring, for it must learn
to associate the will of its rider with the feel of the rein,
before the most powerful bridle can be of any service.

Animals are so abundant in these countries, that hu-
manity and self-interest are not closely united; therefore I
fear it is that the former is here scarcely known. One day,
riding in the Pampas with a very respectable " estanciero,"
my horse, being tired, lagged behind. The man often shouted

166 CHARLES DARWIN

to me to spur him. When I remonstrated that it was a pity,
for the horse was quite exhausted, he cried out, " Why not ?
— never mind — spur him — it is my horse." I had then some
difficulty in making him comprehend that it was for the
horse's sake, and not on his account, that I did not choose
to use my spurs. He exclaimed, with a look of great sur-
prise, " Ah, Don Carlos, que cosa ! " It was clear that such
an idea had never before entered his head.

The Gauchos are well known to be perfect riders. The
idea of being thrown, let the horse do what it likes, never
enters their head. Their criterion of a good rider is, a man
who can manage an untamed colt, or who, if his horse falls,
alights on his own feet, or can perform other such exploits.
I have heard of a man betting that he would throw his horse
down twenty times, and that nineteen times he would not
fall himself. I recollect seeing a Gaucho riding a very
stubborn horse, which three times successively reared so
high as to fall backwards with great violence. The man
judged with uncommon coolness the proper moment for
slipping off, not an instant before or after the right time;
and as soon as the horse got up, the man jumped on his back,
and at last they started at a gallop. The Gaucho never ap-
pears to exert any muscular force. I was one day watching
a good rider, as we were galloping along at a rapid pace,
and thought to myself, " Surely if the horse starts, you
appear so careless on your seat, you must fall." At this mo-
ment, a male ostrich sprang from its nest right beneath the
horse's nose : the young colt bounded on one side like a stag ;
but as for the man, all that could be said was, that he started
and took fright with his horse.

In Chile and Peru more pains are taken with the mouth
of the horse than in La Plata, and this is evidently a conse-
quence of the more intricate nature of the country. In
Chile a horse is not considered perfectly broken, till he can
be brought up standing, in the midst of his full speed, on
any particular spot, — for instance, on a cloak thrown on
the ground: or, again, he will charge a wall, and rearing,
scrape the surface with his hoofs. I have seen an animal
bounding with spirit, yet merely reined by a fore-finger and
thumb, taken at full gallop across a courtyard, and then

THE VOYAGE OF THE BEAGLE 167

made to wheel round the post of a veranda with great speed,
but at so equal a distance, that the rider, with outstretched
arm, all the while kept one finger rubbing the post. Then
making a demi-volte in the air, with the other arm out-
stretched in a like manner, he wheeled round, with aston-
ishing force, in an opposite direction.

Such a horse is well broken; and although this at first
may appear useless, it is far otherwise. It is only carrying
that which is daily necessary into perfection. When a bul-
lock is checked and caught by the lazo, it will sometimes
gallop round and round in a circle, and the horse being
alarmed at the great strain, if not well broken, will not
readily turn like the pivot of a wheel. In consequence many
men have been killed; for if the lazo once takes a twist
round a man's body, it will instantly, from the power of the
two opposed animals, almost cut him in twain. On the
same principle the races are managed ; the course is only
two or three hundred yards long, the wish being to have
horses that can make a rapid dash. The racehorses are
trained not only to stand with their hoofs touching a line,
but to draw all four feet together, so as at the first spring
to bring into play the full action of the hind-quarters. In
Chile I was told an anecdote, which I believe was true; and
it offers a good illustration of the use of a well-broken ani-
mal. A respectable man riding one day met two others, one
of whom was mounted on a horse, which he knew to have
been stolen from himself. He challenged them ; they an-
swered him by drawing their sabres and giving chase. The
man, on his good and fleet beast, kept just ahead: as he
passed a thick bush he wheeled round it, and brought up
his horse to a dead check. The pursuers were obliged to
shoot on one side and ahead. Then instantly dashing on,
right behind them, he buried his knife in the back of one,
wounded the other, recovered his horse from the dying
robber, and rode home. For these feats of horsemanship
two things are necessary: a most severe bit, like the Mame-
luke, the power of which, though seldom used, the horse
knows full well; and large blunt spurs, that can be applied
either as a mere touch, or as an instrument of extreme pain.
I conceive that with English spurs, the slightest touch of

which pricks the skin, it would be impossible to break in a
horse after the South American fashion.

At an estancia near Las Vacas large numbers of mares
are weekly slaughtered for the sake of their hides, although
worth only five paper dollars, or about half a crown apiece.
It seems at first strange that it can answer to kill mares
for such a trifle ; but as it is thought ridiculous in this coun-
try ever to break in or ride a mare, they are of no value
except for breeding. The only thing for which I ever saw
mares used, was to tread out wheat from the ear ; for which
purpose they were driven round a circular enclosure, where
the wheat-sheaves were strewed. The man employed for
slaughtering the mares happened to be celebrated for his
dexterity with the lazo. Standing at the distance of twelve
yards from the mouth of the corral, he has laid a wager
that he would catch by the legs every animal, without miss-
ing one, as it rushed past him. There was another man
who said he would enter the corral on foot, catch a mare,
fasten her front legs together, drive her out, throw her down,
kill, skin, and stake the hide for drying (which latter is a
tedious job) ; and he engaged that he would perform this
whole operation on twenty-two animals in one day. Or he
would kill and take the skin off fifty in the same time. This
would have been a prodigious task, for it is considered a
good day's work to skin and stake the hides of fifteen or
sixteen animals.

November 26th. — I set out on my return in a direct line
for Monte Video. Having heard of some giant's bones at
a neighbouring farm-house on the Sarandis, a small stream
entering the Rio Negro, I rode there accompanied by my
host, and purchased for the value of eighteen pence the head
of the Toxodon.4 When found it was quite perfect; but
the boys knocked out some of the teeth with stones, and then
set up the head as a mark to throw at. By a most fortunate
chance I found a perfect tooth, which exactly fitted one of
the sockets in this skull, embedded by itself on the banks
of the Rio Tercero, at the distance of about 180 miles from
this place. I found remains of this extraordinary animal

* I must express my obligation to Mr. Keane, at whose house I was stay-
ing on the Berquelo, and to Mr. Lumb at Buenos Ayres, for without their
assistance these valuable remains would never have reached England.

THE VOYAGE OF THE BEAGLE 160

at two other places, so that it must formerly have been com-
mon. I found here, also, some large portions of the armour
of a gigantic armadillo-like animal, and part of the great
head of a Mylodon. The bones of this head are so fresh,
that they contain, according to the analysis by Mr. T. Reeks,
seven per cent of animal matter; and when placed in a
spirit-lamp, they burn with a small flame. The number
of the remains embedded in the grand estuary deposit which
forms the Pampas and covers the granitic rocks of Banda
Oriental, must be extraordinarily great. I believe a straight
line drawn in any direction through the Pampas would cut
through some skeleton or bones. Besides those which I
found during my short excursions, I heard of many others,
and the origin of such names as " the stream of the animal,"
" the hill of the giant," is obvious. At other times I heard
of the marvellous property of certain rivers, which had the
power of changing small bones into large ; or, as some main-
tained, the bones themselves grew. As far as I am aware,
not one of these animals perished, as was formerly supposed,
in the marshes or muddy river-beds of the present land, but
. their bones have been exposed by the streams intersecting the
subaqueous deposit in which they were originally embedded.
We may conclude that the whole area of the Pampas is one
wide sepulchre of these extinct gigantic quadrupeds.

By the middle of the day, on the 28th, we arrived at
Monte Video, having been two days and a half on the road.
The country for the whole way was of a very uniform char-
acter, some parts being rather more rocky and hilly than
near the Plata. Not far from Monte Video we passed
through the village of Las Pietras, so named from some
large rounded masses of syenite. Its appearance was rather
pretty. In this country a few fig-trees round a group of
houses, and a site elevated a hundred feet above the gen-
eral level, ought always to be called picturesque.

During the last six months I have had an opportunity of
seeing a little of the character of the inhabitants of these
provinces. The Gauchos, or countrymen, are very superior
to those who reside in the towns. The Gaucho is invariably
most obliging, polite, and hospitable: I did not meet with

170 CHARLES DARWIN

even one instance of rudeness or inhospitality. He is mod-
est, both respecting himself and country, but at the same
time a spirited, bold fellow. On the other hand, many rob-
beries are committed, and there is much bloodshed: the
habit of constantly wearing the knife is the chief cause
of the latter. It is lamentable to hear how many lives are
lost in trifling quarrels. In fighting, each party tries to
mark the face of his adversary by slashing his nose or eyes;
as is often attested by deep and horrid-looking scars. Rob-
beries are a natural consequence of universal gambling,
much drinking, and extreme indolence. At Mercedes I asked
two men why they did not work. One gravely said the days
were too long; the other that he was too poor. The number
of horses and the profusion of food are the destruction of
all industry. Moreover, there are so many feast-days; and
again, nothing can succeed without it be begun when the
moon is on the increase; so that half the month is lost from
these two causes.

Police and justice are quite inefficient. If a man who is
poor commits murder and is taken, he will be imprisoned,
and perhaps even shot; but if he is rich and has friends,
he may rely on it no very severe consequence will ensue.
It is curious that the most respectable inhabitants of the
country invariably assist a murderer to escape : they seem
to think that the individual sins against the government,
and not against the people. A traveller has no protection
besides his fire-arms; and the constant habit of carrying
them is the main check to more frequent robberies.

The character of the higher and more educated classes
•who reside in the towns, partakes, but perhaps in a lesser
degree, of the good parts of the Gaucho, but is, I fear, stained
by many vices of which he is free. Sensuality, mockery of
all religion, and the grossest corruption, are far from un-
common. Nearly every public officer can be bribed. The
head man in the post-office sold forged government franks.
The governor and prime minister openly combined to plun-
der the state. Justice, where gold came into play, was
hardly expected by any one. I knew an Englishman, who
went to the Chief Justice (he told me, that not then under-
standing the ways of the place, he trembled as he entered

THE VOYAGE OF THE BEAGLE 171

the room), and said, " Sir, I have come to offer you two hun-
dred (paper) dollars (value about five pounds sterling) if
you will arrest before a certain time a man who has cheated
me. I know it is against the law, but my lawyer (naming
him) recommended me to take this step." The Chief Jus-
tice smiled acquiescence, thanked him, and the man before
night was safe in prison. With this entire want of prin-
ciple in many of the leading men, with the country full of
ill-paid turbulent officers, the people yet hope that a demo-
cratic form of government can succeed!

On first entering society in these countries, two or three
features strike one as particularly remarkable. The polite
and dignified manners pervading every rank of life, the
excellent taste displayed by the women in their dresses, and
the equality amongst all ranks. At the Rio Colorado some
men who kept the humblest shops used to dine with Gen-
eral Rosas. A son of a major at Bahia Blanca gained his
livelihood by making paper cigars, and he wished to accom-
pany me, as guide or servant, to Buenos Ayres, but his
father objected on the score of the danger alone. Many
officers in the army can neither read nor write, yet all meet
in society as equals. In Entre Rios, the Sala consisted of
only six representatives. One of them kept a common shop,
and evidently was not degraded by the office. All this rs
what would be expected in a new country; nevertheless the
absence of gentlemen by profession appears to an English-
man something strange.

When speaking of these countries, the manner in which
they have been brought up by their unnatural parent, Spain,
should always be borne in mind. On the whole, perhaps,
more credit is due for what has been done, than blame for
that which may be deficient. It is impossible to doubt but
that the extreme liberalism of these countries must ulti-
mately lead to good results. The very general toleration of
foreign religions, the regard paid to the means of education,
the freedom of the press, the facilities offered to all for-
eigners, and especially, as I am bound to add, to every one
professing the humblest pretensions to science, should be
recollected with gratitude by those who have visited Spanish
South America.

December 6th. — The Beagle sailed from the Rio Plata,
never again to enter its muddy stream. Our course was
directed to Port Desire, on the coast of Patagonia. Before
proceeding any further, I will here put together a few
observations made at sea.

Several times when the ship has been some miles off the
mouth of the Plata, and at other times when off the shores
of Northern Patagonia, we have been surrounded by insects.
One evening, when we were about ten miles from the Bay
of San Bias, vast numbers of butterflies, in bands or flocks
of countless myriads, extended as far as the eye could range.
Even by the aid of a telescope it was not possible to see a
space free from butterflies. The seamen cried out " it was
snowing butterflies," and such in fact was the appearance.
More species than one were present, but the main part be-
longed to a kind very similar to, but not identical with, the
common English Colias edusa. Some moths and hymenop-
tera accompanied the butterflies; and a fine beetle (Calo-
soma) flew on board. Other instances are known of this
beetle having been caught far out at sea; and this is the
more remarkable, as the greater number of the Carabidae
seldom or never take wing. The day had been fine and calm,
and the one previous to it equally so, with light and variable
airs. Hence we cannot suppose that the insects were blown
off the land, but we must conclude that they voluntarily took
flight. The great bands of the Colias seem at first to afford
an instance like those on record of the migrations of another
butterfly, Vanessa cardui;5 but the presence of other insects
makes the case distinct, and even less intelligible. Before
sunset a strong breeze sprung up from the north, and this
must have caused tens of thousands of the butterflies and
other insects to have perished.

On another occasion, when seventeen miles off Cape Cor-
rientes, I had a net overboard to catch pelagic animals.
Upon drawing it up, to my surprise, I found a considerable
number of beetles in it, and although in the open sea, they
did not appear much injured by the salt water. I lost some
of the specimens, but those which I preserved belonged
to the genera Colymbetes, Hydroporus, Hydrobius (two spe-

8 Lyell's Principles of Geology, vol. iii. p. 63.

THE VOYAGE OF THE BEAGLE 173

cies), Notaphus, Cynucus, Adimonia, and Scavabaeus. At
first I thought that these insects had been blown from the
shore; but upon reflecting that out of the eight species four
were aquatic, and two others partly so in their habits, it
appeared to me most probable that they were floated into the
sea by a small stream which drains a lake near Cape Cor-
rientes. On any supposition it is an interesting circum-
stance to find live insects swimming in the open ocean seven-
teen miles from the nearest point of land. There are several
accounts of insects having been blown off the Patagonian
shore. Captain Cook observed it, as did more lately Captain
King of the Adventure. The cause probably is due to the
want of shelter, both of trees and hills, so that an insect on
the wing with an off-shore breeze, would be very apt to
be blown out to sea. The most remarkable instance I have
known of an insect being caught far from the land, was that
of a large grasshopper (Acrydium), which flew on board,
when the Beagle was to windward of the Cape de Verd
Islands, and when the nearest point of land, not directly
opposed to the trade-wind, was Cape Blanco on the coast of
Africa, 370 miles distant.*

On several occasions, when the Beagle has been within
the mouth of the Plata, the rigging has been coated with
the web of the Gossamer Spider. One day (November ist,
1832) I paid particular attention to this subject. The weather
had been fine and clear, and in the morning the air was full
of patches of the flocculent web, as on an autumnal day in
England. The ship was sixty miles distant from the land, in
the direction of a steady though light breeze. Vast numbers
of a small spider, about one-tenth of an inch in length, and of
a dusky red colour, were attached to the webs. There must
have been, I should suppose, some thousands on the ship. The
little spider, when first coming in contact with the rigging,
was always seated on a single thread, and not on the floccu-
lent mass. This latter seems merely to be produced by the
entanglement of the single threads. The spiders were all of
one species, but of both sexes, together with young ones.
These latter were distinguished by their smaller size and

passage from harbour to harbour, wandering from the vessel, are soon lost,
and all disappear.

more dusky colour. I will not give the description of this
spider, but merely state that it does not appear to me to be
included in any of Latreille's genera. The little aeronaut as
soon as it arrived on board was very active, running about,
sometimes letting itself fall, and then reascending the same
thread; sometimes employing itself in making a small and
very irregular mesh in the corners between the ropes. It
could run with facility on the surface of the water. When
disturbed it lifted up its front legs, in the attitude of atten-
tion. On its first arrival it appeared very thirsty, and with
exserted maxillae drank eagerly of drops of water ; this same
circumstance has been observed by Strack: may it not be in
consequence of the little insect having passed through a dry
and rarefied atmosphere? Its stock of web seemed inex-
haustible. While watching some that were suspended by a
single thread, I several times observed that the slightest
breath of air bore them away out of sight, in a horizontal
line.

On another occasion (25th) under similar circumstances,
I repeatedly observed the same kind of small spider,
either when placed or having crawled on some little emi-
nence, elevate its abdomen, send forth a thread, and then
sail away horizontally, but with a rapidity which was quite
unaccountable. I thought I could perceive that the spider,
before performing the above preparatory steps, connected
its legs together with the most delicate threads, but I am not
sure whether this observation was correct.

One day, at St. Fe, I had a better opportunity of observing
some similar facts. A spider which was about three-tenths
of an inch in length, and which in its general appearance
resembled a Citigrade (therefore quite different from the
gossamer), while standing on the summit of a post, darted
forth four or five threads from its spinners. These, glitter-
ing in the sunshine, might be compared to diverging rays of
light; they were not, however, straight, but in undulations
like films of silk blown by the wind. They were more than a
yard in length, and diverged in an ascending direction from
the orifices. The spider then suddenly let go its hold of the
post, and was quickly borne out of sight. The day was hot
and apparently calm; yet under such circumstances, the at-

THE VOYAGE OF THE BEAGLE 175

mosphere can never be so tranquil as not to affect a vane so
delicate as the thread of a spider's web. If during a warm
day we look either at the shadow of any object cast on a
bank, or over a level plain at a distant landmark, the effect
of an ascending current of heated air is almost always evi-
dent: such upward currents, it has been remarked, are also
shown by the ascent of soap-bubbles, which will not rise in
an in-doors room. Hence I think there is not much difficulty
in understanding the ascent of the fine lines projected from
a spider's spinners, and afterwards of the spider itself; the
divergence of the lines has been attempted to be explained, I
believe by Mr. Murray, by their similar electrical condition.
The circumstance of spiders of the same species, but of dif-
ferent sexes and ages, being found on several occasions at
the distance of many leagues from the land, attached in vast
numbers to the lines, renders it probable that the habit of
sailing through the air is as characteristic of this tribe, as
that of diving is of the Argyroneta. We may then reject
Latreille's supposition, that the gossamer owes its origin
indifferently to the young of several genera of spiders:
although, as we have seen, the young of other spiders do
possess the power of performing aerial voyages.7

During our different passages south of the Plata, I often
towed astern a net made of bunting, and thus caught many
curious animals. Of Crustacea there were many strange
and undescribed genera. One, which in some respects is
allied to the Notopods (or those crabs which have their
posterior legs placed almost on their backs, for the purpose
of adhering to the under side of rocks), is very remarkable
from the structure of its hind pair of legs. The penultimate
joint, instead of terminating in a simple claw, ends in three
bristle-like appendages of dissimilar lengths — the longest
equalling that of the entire leg. These claws are very thin,
and are serrated with the finest teeth, directed backwards:
their curved extremities are flattened, and on this part five
most minute cups are placed which seem to act in the same
manner as the suckers on the arms of the cuttle-fish. As
the animal lives in the open sea, and probably wants a place

tions on the habits of spiders.

176 CHARLES DARWIN

of rest, I suppose this beautiful and most anomalous struc-
ture is adapted to take hold of floating marine animals.

In deep water, far from the land, the number of living
creatures is extremely small: south of the latitude 35°, I
never succeeded in catching anything besides some beroe,
and a few species of minute entomostracous crustacea.
In shoaler water, at the distance of a few miles from the
coast, very many kinds of crustacea and some other animals
are numerous, but only during the night. Between latitudes
56° and 57° south of Cape Horn, the net was put astern
several times ; it never, however, brought up anything besides
a few of two extremely minute species of Entomostraca.
Yet whales and seals, petrels and albatross, are exceedingly
abundant throughout this part of the ocean. It has always
been a mystery to me on what the albatross, which lives far
from the shore, can subsist ; I presume that, like the condor,
it is able to fast long ; and that one good feast on the carcass
of a putrid whale lasts for a long time. The central and
intertropical parts of the Atlantic swarm with Pteropoda,
Crustacea, and Radiata, and with their devourers the flying-
fish, and again with their devourers the bonitos and albi-
cores; I presume that the numerous lower pelagic animals
feed on the Infusoria, which are now known, from the
researches of Ehrenberg, to abound in the open ocean: but
on what, in the clear blue water, do these Infusoria subsist?

While sailing a little south of the Plata on one very dark
night, the sea presented a wonderful and most beautiful
spectacle. There was a fresh breeze, and every part of the
surface, which during the day is seen as foam, now glowed
with a pale light. The vessel drove before her bows two
billows of liquid phosphorus, and in her wake she was fol-
lowed by a milky train. As far as the eye reached, the crest
of every wave was bright, and the sky above the horizon,
from the reflected glare of these livid flames, was not so
utterly obscure as over the vault of the heavens.

As we proceed further southward the sea is seldom phos-
phorescent; and off Cape Horn I do not recollect more than
once having seen it so, and then it was far from being bril-
liant. This circumstance probably has a close connection
with the scarcity of organic beings in that part of the ocean.

THE VOYAGE OF THE BEAGLE 177

After the elaborate paper,8 by Ehrenberg, on the phos-
phorescence of the sea, it is almost superfluous on my part
to make any observations on the subject. I may however
add, that the same torn and irregular particles of gelatinous
matter, described by Ehrenberg, seem in the southern as
well as in the northern hemisphere, to be the common cause
of this phenomenon. The particles were so minute as easily
to pass through fine gauze ; yet many were distinctly visible
by the naked eye. The water when placed in a tumbler and
agitated, gave out sparks, but a small portion in a watch-
glass scarcely ever was luminous. Ehrenberg states that
these particles all retain a certain degree of irritability. My
observations, some of which were made directly after taking
up the water, gave a different result. I may also mention,
that having used the net during one night, I allowed it to
become partially dry, and having occasion twelve hours
afterwards to employ it again, I found the whole surface
sparkled as brightly as when first taken out of the water.
It does not appear probable in this case, that the particles
could have remained so long alive. On one occasion having
kept a jelly-fish of the genus Dianaea till it was dead, the
water in which it was placed became luminous. When the
waves scintillate with bright green sparks, I believe it is
generally owing to minute Crustacea. But there can be no
doubt that very many other pelagic animals, when alive, are
phosphorescent.

On two occasions I have observed the sea luminous at
considerable depths beneath the surface. Near the mouth
of the Plata some circular and oval patches, from two to
four yards in diameter, and with defined outlines, shone with
a steady but pale light; while the surrounding water only
gave out a few sparks. The appearance resembled the reflec-
tion of the moon, or some luminous body ; for the edges were
sinuous from the undulations of the surface. The ship,
which drew thirteen feet of water, passed over, without dis-
turbing these patches. Therefore we must suppose that some
animals were congregated together at a greater depth than
the bottom of the vessel.

Near Fernando Noronha the sea gave out light in flashes.

178 CHARLES DARWIN

The appearance was very similar to that which might be
expected from a large fish moving rapidly through a lumi-
nous fluid. To this cause the sailors attributed it; at the
time, however, I entertained some doubts, on account of the
frequency and rapidity of the flashes. I have already
remarked that the phenomenon is very much more common
in warm than in cold countries; and I have sometimes im-
agined that a disturbed electrical condition of the atmos-
phere was most favourable to its production. Certainly I
think the sea is most luminous after a few days of more
calm weather than ordinary, during which time it has
swarmed with various animals. Observing that the water
charged with gelatinous particles is in an impure state, and
that the luminous appearance in all common cases is pro-
duced by the agitation of the fluid in contact with the atmos-
phere, I am inclined to consider that the phosphorescence is
the result of the decomposition of the organic particles, by
which process (one is tempted almost to call it a kind of
respiration) the ocean becomes purified.

December 2$rd. — We arrived at Port Desire, situated in
lat. 47°, on the coast of Patagonia. The creek runs for
about twenty miles inland, with an irregular width. The
Beagle anchored a few miles within the entrance, in front of
the ruins of an old Spanish settlement.

The same evening I went on shore. The first landing in
any new country is very interesting, and especially when, as in
this case, the whole aspect bears the stamp of a marked and
individual character. At the height of between two and
three hundred feet above some masses of porphyry a wide
plain extends, which is truly characteristic of Patagonia.
The surface is quite level, and is composed of well-rounded
shingle mixed with a whitish earth. Here and there scat-
tered tufts of brown wiry grass are supported, and still more
rarely, some low thorny bushes. The weather is dry and
pleasant, and the fine blue sky is but seldom obscured. When
standing in the middle of one of these desert plains and
looking towards the interior, the view is generally bounded
by the escarpment of another plain, rather higher, but equally
level and desolate; and in every other direction the horizon

THE VOYAGE OF THE BEAGLE 179

is indistinct from the trembling mirage which seems to rise
from the heated surface.

In such a country the fate of the Spanish settlement was
soon decided; the dryness of the climate during the greater
part of the year, and the occasional hostile attacks of the
wandering Indians, compelled the colonists to desert their
half-finished buildings. The style, however, in which they
were commenced shows the strong and liberal hand of Spain
in the old time. The result of all the attempts to colonize this
side of America south of 41°, has been miserable. Port
Famine expresses by its name the lingering and extreme
sufferings of several hundred wretched people, of whom one
alone survived to relate their misfortunes. At St. Joseph's
Bay, on the coast of Patagonia, a small settlement was made ;
but during one Sunday the Indians made an attack and mas-
sacred the whole party, excepting two men, who remained
captives during many years. At the Rio Negro I conversed
with one of these men, now in extreme old age.

The zoology of Patagonia is as limited as its flora.* On
the arid plains a few black beetles (Heteromera) might be
seen slowly crawling about, and occasionally a lizard darted
from side to side. Of birds we have three carrion hawks,
and in the valleys a few finches and insect-feeders. An ibis
(Theristicus melanops — a species said to be found in cen-
tral Africa) is not uncommon on the most desert parts: in
their stomachs I found grasshoppers, cicadas, small lizards,
and even scorpions.10 At one time of the year these birds
go in flocks, at another in pairs; their cry is very loud and
singular, like the neighing of the guanaco.

The guanaco, or wild llama, is the characteristic quadru-
ped of the plains of Patagonia; it is the South American
representative of the camel of the East. It is an elegant
animal in a state of nature, with a long slender neck and

* I found here a species of cactus, described by Professor Henslow, under
the name of Opuntta Darwinii (Magazine of Zoology and Botany, vol. i.
p. 466), which was remarkable for the irritability of the stamens, when I
inserted either a piece of stick or the end of my_ finger in the flower. The
segments of the perianth also closed on the pistil, but more slowly than
the stamens. Plants of this family, generally considered as tropical, occur
in North America (Lewis and Clarke's Travels, p. 221), in the same high
latitude as here, namely, in both cases, in 47°.

10 These insects were not uncommon beneath stones. I found one can-
nibal scorpion quietly devouring another.

fine legs. It is very common over the whole of the temperate
parts of the continent, as far south as the islands near Cape
Horn. It generally lives in small herds of from half a dozen
to thirty in each ; but on the banks of the St. Cruz we saw
one herd which must have contained at least five hundred.

They are generally wild and extremely wary. Mr. Stokes
told me, that he one day saw through a glass a herd of these
animals which evidently had been frightened, and were run-
ning away at full speed, although their distance was so great
that he could not distinguish them with his naked eye. The
sportsman frequently receives the first notice of their pres-
ence, by hearing from a long distance their peculiar shrill
neighing note of alarm. If he then looks attentively, he will
probably see the herd standing in a line on the side of some
distant hill. On approaching nearer, a few more squeals are
given, and off they set at an apparently slow, but really quick
canter, along some narrow beaten track to a neighbouring
hill. If, however, by chance he abruptly meets a single ani-
mal, or several together, they will generally stand motionless
and intently gaze at him ; then perhaps move on a few yards,
turn round, and look again. What is the cause of this differ-
ence in their shyness? Do they mistake a man in the dis-
tance for their chief enemy the puma? Or does curiosity
overcome their timidity? That they are curious is certain;
for if a person lies on the ground, and plays strange antics,
such as throwing up his feet in the air, they will almost
always approach by degrees to reconnoitre him. It was an
artifice that was repeatedly practised by our sportsmen with
success, and it had moreover the advantage of allowing sev-
eral shots to be fired, which were all taken as parts of the
performance. On the mountains of Tierra del Fuego, I have
more than once seen a guanaco, on being approached, not
only neigh and squeal, but prance and leap about in the most
ridiculous manner, apparently in defiance as a challenge.
These animals are very easily domesticated, and I have seen
some thus kept in northern Patagonia near a house, though
not under any restraint. They are in this state very bold, and
readily attack a man by striking him from behind with both
knees. It is asserted that the motive for these attacks is
jealousy on account of their females. The wild guanacos,

THE VOYAGE OF THE BEAGLE 181

however, have no idea of defence; even a single dog will
secure one of these large animals, till the huntsman can come
up. In many of their habits they are like sheep in a flock.
Thus when they see men approaching in several directions
on horseback, they soon become bewildered, and know not
which way to run. This greatly facilitates the Indian method
of hunting, for they are thus easily driven to a central point,
and are encompassed.

The guanacos readily take to the water: several times at
Port Valdes they were seen swimming from island to island.
Byron, in his voyage, says he saw them drinking salt water.
Some of our officers likewise saw a herd apparently drinking
the briny fluid from a salina near Cape Blanco. I imagine
in several parts of the country, if they do not drink salt
water, they drink none at all. In the middle of the day they
frequently roll in the dust, in saucer-shaped hollows. The
males fight together; two one day passed quite close to me,
squealing and trying to bite each other ; and several were
shot with their hides deeply scored. Herds sometimes appear
to set out on exploring parties: at Bahia Blanca, where,
within thirty miles of the coast, these animals are extremely
unfrequent, I one day saw the tracks of thirty or forty, which
had come in a direct line to a muddy salt-water creek. They
then must have perceived that they were approaching the
sea, for they had wheeled with the regularity of cavalry, and
had returned back in as straight a line as they had advanced.
The guanacos have one singular habit, which is to me quite
inexplicable ; namely, that on successive days they drop their
dung in the same defined heap. I saw one of these heaps
which was eight feet in diameter, and was composed of a
large quantity. This habit, according to M. A. d'Orbigny, is
common to all the species of the genus; it is very useful to
the Peruvian Indians, who use the dung for fuel, and are
thus saved the trouble of collecting it.

The guanacos appear to have favourite spots for lying
down to die. On the banks of the St. Cruz, in certain cir-
cumscribed spaces, which were generally bushy and all near
the river, the ground was actually white with bones. On one
such spot I counted between ten and twenty heads. I par-
ticularly examined the bones; they did not appear, as some

182 CHARLES DARWIN

scattered ones which I had seen, gnawed or broken, as if
dragged together by beasts of prey. The animals in most
cases must have crawled, before dying, beneath and amongst
the bushes. Mr. Bynoe informs me that during a former
voyage he observed the same circumstance on the banks of
the Rio Gallegos. I do not at all understand the reason of
this, but I may observe, that the wounded guanacos at the
St. Cruz invariably walked towards the river. At St. Jago
in the Cape de Verd Islands, I remember having seen in a
ravine a retired corner covered with bones of the goat; we
at the time exclaimed that it was the burial ground of all the
goats in the island. I mention these trifling circumstances,
because in certain cases they might explain the occurrence
of a number of uninjured bones in a cave, or buried under
alluvial accumulations ; and likewise the cause why certain
animals are more commonly embedded than others in sedi-
mentary deposits.

One day the yawl was sent under the command of Mr.
Chaffers with three days' provisions to survey the upper part
of the harbour. In the morning we searched for some water-
ing-places mentioned in an old Spanish chart. We found one
creek, at the head of which there was a trickling rill (the
first we had seen) of brackish water. Here the tide com-
pelled us to wait several hours ; and in the interval I walked
some miles into the interior. The plain as usual consisted
of gravel, mingled with soil resembling chalk in appearance,
but very different from it in nature. From the softness of
these materials it was worn into many gulleys. There was
not a tree, and, excepting the guanaco, which stood on the
hill-top a watchful sentinel over its herd, scarcely an animal
or a bird. All was stillness and desolation. Yet in passing
over these scenes, without one bright object near, an ill-
defined but strong sense of pleasure is vividly excited. One
asked how many ages the plain had thus lasted, and how
many more it was doomed thus to continue.

" None can reply — all seems eternal now.
The wilderness has a mysterious tongue,
Which teaches awful doubt. "u

11 Shelley, Lines on Mt. Blanc.

THE VOYAGE OF THE BEAGLE 183

In the evening we sailed a few miles further up, and then
pitched the tents for the night. By the middle of the next
day the yawl was aground, and from the shoalness of the
water could not proceed any higher. The water being found
partly fresh, Mr. Chaffers took the dingey and went up two
or three miles further, where she also grounded, but in a
fresh-water river. The water was muddy, and though the
stream was most insignificant in size, it would be difficult to
account for its origin, except from the melting snow on the
Cordillera. At the spot where we bivouacked, we were sur-
rounded by bold cliffs and steep pinnacles of porphyry. I do
not think I ever saw a spot which appeared more secluded
from the rest of the world, than this rocky crevice in the
wide plain.

The second day after our return to the anchorage, a party
of officers and myself went to ransack an old Indian grave,
which I had found on the summit of a neighbouring hill.
Two immense stones, each probably weighing at least a
couple of tons, had been placed in front of a ledge of rock
about six feet high. At the bottom of the grave on the hard
rock there was a layer of earth about a foot deep, which
must have been brought up from the plain below. Above it a
pavement of flat stones was placed, on which others were
piled, so as to fill up the space between the ledge and the two
great blocks. To complete the grave, the Indians had con-
trived to detach from the ledge a huge fragment, and to
throw it over the pile so as to rest on the two blocks. We
undermined the grave on both sides, but could not find any
relics, or even bones. The latter probably had decayed long
since (in which case the grave must have been of extreme
antiquity), for I found in another place some smaller heaps,
beneath which a very few crumbling fragments could yet be
distinguished as having belonged to a man. Falconer states,
that where an Indian dies he is buried, but that subsequently
his bones are carefully taken up and carried, let the distance
be ever so great, to be deposited near the sea-coast. This
custom, I think, may be accounted for by recollecting, that
before the introduction of horses, these Indians must have
led nearly the same life as the Fuegians now do, and there-
fore generally have resided in the neighbourhood of the sea.

184 CHARLES DARWIN

The common prejudice of lying where one's ancestors have
lain, would make the now roaming Indians bring the less
perishable part of their dead to their ancient burial-ground
on the coast.

January pth, 1834. — Before it was dark the Beagle an-
chored in the fine spacious harbour of Port St. Julian, situated
about one hundred and ten miles to the south of Port Desire.
We remained here eight days. The country is nearly similar
to that of Port Desire, but perhaps rather more sterile. One
day a party accompanied Captain Fitz Roy on a long walk
round the head of the harbour. We were eleven hours with-
out tasting any water, and some of the party were quite
exhausted. From the summit of a hill (since well named
Thirsty Hill) a fine lake was spied, and two of the party pro-
ceeded with concerted signals to show whether it was fresh
water. What was our disappointment to find a snow-white
expanse of salt, crystallized in great cubes! We attributed
our extreme thirst to the dryness of the atmosphere; but
whatever the cause might be, we were exceedingly glad late
in the evening to get back to the boats. Although we could
nowhere find, during our whole visit, a single drop of fresh
water, yet some must exist ; for by an odd chance I found on
the surface of the salt water, near the head of the bay, a
Colymbetes not quite dead, which must have lived in some
not far distant pool. Three other insects (a Cincindela, like
hybrida, a Cymindis, and a Harpalus, which all live on muddy
flats occasionally overflowed by the sea), and one other
found dead on the plain, complete the list of the beetles. A
good-sized fly (Tabanus) was extremely numerous, and tor-
mented us by its painful bite. The common horsefly, which
is so troublesome in the shady lanes of England, belongs to
this same genus. We here have the puzzle that so frequently
occurs in the case of musquitoes — on the blood of what
animals do these insects commonly feed? The guanaco is
nearly the only warm-blooded quadruped, and it is found in
quite inconsiderable numbers compared with the multitude
of flies.

The geology of Patagonia is interesting. Differently from
Europe, where the tertiary formations appear to have accu-

THE VOYAGE OP THE BEAGLE 185

mulated in bays, here along hundreds of miles of coast we
have one great deposit, including many tertiary shells, all
apparently extinct. The most common shell is a massive
gigantic oyster, sometimes even a foot in diameter. These
beds are covered by others of a peculiar soft white stone, in-
cluding much gypsum, and resembling chalk, but really of
a pumiceous nature. It is highly remarkable, from being
composed, to at least one-tenth of its bulk, of Infusoria.
Professor Ehrenberg has already ascertained in it thirty
oceanic forms. This bed extends for 500 miles along the coast,
and probably for a considerably greater distance. At Port
St. Julian its thickness is more than 800 feet ! These white
beds are everywhere capped by a mass of gravel, forming
probably one of the largest beds of shingle in the world: it
certainly extends from near the Rio Colorado to between 600
and 700 nautical miles southward; at Santa Cruz (a river a
little south of St. Julian), it reaches to the foot of the Cor-
dillera ; half way up the river, its thickness is more than 200
feet; it probably everywhere extends to this great chain,
whence the well-rounded pebbles of porphyry have been
derived: we may consider its average breadth as 200 miles,
and its average thickness as about 50 feet. If this great bed
of pebbles, without including the mud necessarily derived
from their attrition, was piled into a mound, it would form a
great mountain chain ! When we consider that all these
pebbles, countless as the grains of sand in the desert, have
been derived from the slow falling of masses of rock on the
old coast-lines and banks of rivers ; and that these fragments
have been dashed into smaller pieces, and that each of them
has since been slowly rolled, rounded, and far transported,
the mind is stupefied in thinking over the long, absolutely
necessary, lapse of years. Yet all this gravel has been trans-
ported, and probably rounded, subsequently to the deposition
of the white beds, and long subsequently to the underlying
beds with the tertiary shells.

Everything in this southern continent has been effected
on a grand scale : the land, from the Rio Plata to Tierra del
Fuego, a distance of 1200 miles, has been raised in mass (and
in Patagonia to a height of between 300 and 400 feet), within
the period of the now existing sea-shells. The old and

186 CHARLES DARWIN

weathered shells left on the surface of the upraised plain still
partially retain their colours. The uprising movement has
been interrupted by at least eight long periods of rest, during
which the sea ate deeply back into the land, forming at suc-
cessive levels the long lines of cliffs, or escarpments, which
separate the different plains as they rise like steps one behind
the other. The elevatory movement, and the eating-back
power of the sea during the periods of rest, have been
equable over long lines of coast; for I was astonished to
find that the step-like plains stand at nearly corresponding
heights at far distant points. The lowest plain is 90 feet
high; and the highest, which I ascended near the coast, is
950 feet; and of this, only relics are left in the form of flat
gravel-capped hills. The upper plain of Santa Cruz slopes
up to a height of 3000 feet at the foot of the Cordillera. I
have said that within the period of existing sea-shells, Pata-
gonia has been upraised 300 to 400 feet : I may add, that
within the period when icebergs transported boulders over
the upper plain of Santa Cruz, the elevation has been at least
1500 feet. Nor has Patagonia been affected only by upward
movements: the extinct tertiary shells from Port St. Julian
and Santa Cruz cannot have lived, according to Professor E.
Forbes, in a greater depth of water than from 40 to 250 feet;
but they are now covered with sea-deposited strata from 800
to 1000 feet in thickness : hence the bed of the sea, on which
these shells once lived, must have sunk downwards several
hundred feet, to allow of the accumulation of the superincum-
bent strata. What a history of geological changes does the
simply-constructed coast of Patagonia reveal !

At Port St. Julian,12 in some red mud capping the gravel
on the 90- feet plain, I found half the skeleton of the Macrau-
chenia Patachonica, a remarkable quadruped, full as large as
a camel. It belongs to the same division of the Pachy-
dermata with the rhinoceros, tapir, and palaeotherium ; but
in the structure of the bones of its long neck it shows a clear
relation to the camel, or rather to the guanaco and llama.
From recent sea-shells being found on two of the higher

u I have lately heard that Capt. Sulivan, R.N., has found numerous fossil
bones, embedded in regular strata, on the banks of the R. Gallegos, in lat.
51° 4'. Some of the bones are large; others are small, and appear to have
belonged to an armadillo. This is a most interesting and important discovery.

THE VOYAGE OF THE BEAGLE 187

step-formed plains, which must have been modelled and
upraised before the mud was deposited in which the Macrau-
chenia was entombed, it is certain that this curious quadru-
ped lived long after the sea was inhabited by its present
shells. I was at first much surprised how a large quadruped
could so lately have subsisted, in lat. 49° 15', on these
wretched gravel plains, with their stunted vegetation ; but
the relationship of the Macrauchenia to the Guanaco, now
an inhabitant of the most sterile parts, partly explains this
difficulty.

The relationship, though distant, between the Macrau-
chenia and the Guanaco, between the Toxodon and the
Capybara, — the closer relationship between the many extinct
Edentata and the living sloths, ant-eaters, and armadillos,
now so eminently characteristic of South American zoology,
— and the still closer relationship between the fossil and liv-
ing species of Ctenomys and Hydrochaerus, are most inter-
esting facts. This relationship is shown wonderfully — as
wonderfully as between the fossil and extinct Marsupial
animals of Australia — by the great collection lately brought
to Europe from the caves of Brazil by MM. Lund and Clau-
sen. In this collection there are extinct species of all the
thirty-two genera, excepting four, of the terrestrial quadru-
peds now inhabiting the provinces in which the caves occur ;
and the extinct species are much more numerous than those
now living: there are fossil ant-eaters, armadillos, tapirs,
peccaries, guanacos, opossums, and numerous South Ameri-
can gnawers and monkeys, and other animals. This wonder-
ful relationship in the same continent between the dead and
the living, will, I do not doubt, hereafter throw more light
on the appearance of organic beings on our earth, and their
disappearance from it, than any other class of facts.

It is impossible to reflect on the changed state of the
American continent without the deepest astonishment. For-
merly it must have swarmed with great monsters: now we
find mere pigmies, compared with the antecedent, allied
races. If Buffon had known of the gigantic sloth and arma-
dillo-like animals, and of the lost Pachydermata, he might
have said with a greater semblance of truth that the creative
force in America had lost its power, rather than that it had

188 CHARLES DARWIN

never possessed great vigour. The greater number, if not all,
of these extinct quadrupeds lived at a late period, and were
the contemporaries of most of the existing sea-shells. Since
they lived, no very great change in the form of the land can
have taken place. What, then, has exterminated so many
species and whole genera? The mind at first is irresistibly
hurried into the belief of some great catastrophe ; but thus
to destroy animals, both large and small, in Southern Pata-
gonia, in Brazil, on the Cordillera of Peru, in North America
up to Behring's Straits, we must shake the entire framework
of the globe. An examination, moreover, of the geology of
La Plata and Patagonia, leads to the belief that all the fea-
tures of the land result from slow and gradual changes. It
appears from the character of the fossils in Europe, Asia,
Australia, and in North and South America, that those con-
ditions which favour the life of the larger quadrupeds were
lately co-extensive with the world: what those conditions
were, no one has yet even conjectured. It could hardly have
been a change of temperature, which at about the same time
destroyed the inhabitants of tropical, temperate, and arctic
latitudes on both sides of the globe. In North America we
positively know from Mr. Lyell, that the large quadrupeds
lived subsequently to that period, when boulders were
brought into latitudes at which icebergs now never arrive:
from conclusive but indirect reasons we may feel sure, that
in the southern hemisphere the Macrauchenia, also, lived
long subsequently to the ice-transporting boulder-period. Did
man, after his first inroad into South America, destroy, as
has been suggested, the unwieldy Megatherium and the
other Edentata? We must at least look to some other cause
for the destruction of the little tucutuco at Bahia Blanca, and
of the many fossil mice and other small quadrupeds in
Brazil. No one will imagine that a drought, even far severer
than those which cause such losses in the provinces of La
Plata, could destroy every individual of every species from
Southern Patagonia to Behring's Straits. What shall we say
of the extinction of the horse ? Did those plains fail of pas-
ture, which have since been overrun by thousands and hun-
dreds of thousands of the descendants of the stock intro-
duced by the Spaniards? Have the subsequently introduced

THE VOYAGE OF THE BEAGLE 189

species consumed the food of the great antecedent races?
Can we believe that the Capybara has taken the food of the
Toxodon, the Guanaco of the Macrauchenia, the existing
small Edentata of their numerous gigantic prototypes? Cer-
tainly, no fact in the long history of the world is so startling
as the wide and repeated exterminations of its inhabitants.

Nevertheless, if we consider the subject under another
point of view, it will appear less perplexing. We do not
steadily bear in mind, how profoundly ignorant we are of the
conditions of existence of every animal; nor do we always
remember, that some check is constantly preventing the too
rapid increase of every organized being left in a state of na-
ture. The supply of food, on an average, remains constant ; yet
the tendency in every animal to increase by propagation is
geometrical; and its surprising effects have nowhere been
more astonishingly shown, than in the case of the European
animals run wild during the last few centuries in America.
Every animal in a state of nature regularly breeds; yet in a
species long established, any great increase in numbers is
obviously impossible, and must be checked by some means.
We are, nevertheless, seldom able with certainty to tell in
any given species, at what period of life, or at what period
of the year, or whether only at long intervals, the check
falls; or, again, what is the precise nature of the check.
Hence probably it is, that we feel so little surprise at one, of
two species closely allied in habits, being rare and the other
abundant in the same district; or, again, that one should be
abundant in one district, and another, filling the same place
in the economy of nature, should be abundant in a neighbour-
ing district, differing very little in its conditions. If asked
how this is, one immediately replies that it is determined by
some slight difference, in climate, food, or the number of
enemies: yet how rarely, if ever, we can point out the pre-
cise cause and manner of action of the check! We are,
therefore, driven to the conclusion, that causes generally
quite inappreciable by us, determine whether a given species
shall be abundant or scanty in numbers.

In the cases where we can trace the extinction of a
species through man, either wholly or in one limited district,
we know that it becomes rarer and rarer, and is then lost:

190 CHARLES DARWIN

it would be difficult to point out any just distinction11
between a species destroyed by man or by the increase of its
natural enemies. The evidence of rarity preceding extinc-
tion, is more striking in the successive tertiary strata, as
remarked by several able observers ; it has often been found
that a shell very common in a tertiary stratum is now most
rare, and has even long been thought to be extinct. If then,
as appears probable, species first become rare and then
extinct — if the too rapid increase of every species, even the
most favoured, is steadily checked, as we must admit, though
how and when it is hard to say — and if we see, without the
smallest surprise, though unable to assign the precise reason,
one species abundant and another closely allied species rare
in the same district — why should we feel such great aston-
ishment at the rarity being carried a step further to extinc-
tion ? An action going on, on every side of us, and yet barely
appreciable, might surely be carried a little further, without
exciting our observation. Who would feel any great sur-
prise at hearing that the Magalonyx was formerly rare com-
pared with the Megatherium, or that one of the fossil mon-
keys was few in number compared with one of the now
living monkeys? and yet in this comparative rarity, we
should have the plainest evidence of less favourable condi-
tions for their existence. To admit that species generally
become rare before they become extinct — to feel no surprise
at the comparative rarity of one species with another, and
yet to call in some extraordinary agent and to marvel greatly
when a species ceases to exist, appears to me much the same
as to admit that sickness in the individual is the prelude
to death — to feel no surprise at sickness — but when the sick
man dies to wonder, and to believe that he died through
violence.

13 See the excellent remarks on this subject by Mr. Lyell, in his Principles
of Geology.

APRIL ijth, 1834. — The Beagle anchored within the
£\ mouth of the Santa Cruz. This river is situated
about sixty miles south of Port St. Julian. During
the last voyage Captain Stokes proceeded thirty miles up it,
but then, from the want of provisions, was obliged to re-
turn. Excepting what was discovered at that time, scarcely
anything was known about this large river. Captain Fitz
Roy now determined to follow its course as far as time
would allow. On the i8th three whale-boats started, carry-
ing three weeks' provisions; and the party consisted of
twenty-five souls — a force which would have been sufficient
to have defied a host of Indians. With a strong flood-tide
and a fine day we made a good run, soon drank some of the
fresh water, and were at night nearly above the tidal in-
fluence.

The river here assumed a size and appearance which,
even at the highest point we ultimately reached, was scarcely
diminished. It was generally from three to four hundred
yards broad, and in the middle about seventeen feet deep.
The rapidity of the current, which in its whole course runs
at the rate of from four to six knots an hour, is perhaps its
most remarkable feature. The water is of a fine blue colour,
but with a slight milky tinge, and not so transparent as at
first sight would have been expected. It flows over a bed of

191

192 CHARLES DARWIN

pebbles, like those which compose the beach and the sur-
rounding plains. It runs in a winding course through a
valley, which extends in a direct line westward. This valley
varies from five to ten miles in breadth ; it is bounded by
step-formed terraces, which rise in most parts, one above the
other, to the height of five hundred feet, and have on the
opposite sides a remarkable correspondence.

April ipth. — Against so strong a current it was, of
course, quite impossible to row or sail: consequently the
three boats were fastened together head and stern, two hands
left in each, and the rest came on shore to track. As the
general arrangements made by Captain Fitz Roy were very
good for facilitating the work of all, and as all had a share
in it, I will describe the system. The party including every
one, was divided into two spells, each of which hauled at the
tracking line alternately for an hour and a half. The offi-
cers of each boat lived with, ate the same food, and slept
in the same tent with their crew, so that each boat was
quite independent of the others. After sunset the first level
spot where any bushes were growing, was chosen for our
night's lodging. Each of the crew took it in turns to be
cook. Immediately the boat was hauled up, the cook made
his fire; two others pitched the tent; the coxswain handed
the things out of the boat; the rest carried them up to the
tents and collected firewood. By this order, in half an hour
everything was ready for the night. A watch of two men
and an officer was always kept, whose duty it was to look
after the boats, keep up the fire, and guard against Indians.
Each in the party had his one hour every night.

During this day we tracked but a short distance, for there
were many islets, covered by thorny bushes, and the chan-
nels between them were shallow.

April 20th. — We passed the islands and set to work. Our
regular day's march, although it was hard enough, carried
us on an average only ten miles in a straight line, and per-
haps fifteen or twenty altogether. Beyond the place where
we slept last night, the country is completely terra incognita,
for it was there that Captain Stokes turned back. We saw
in the distance a great smoke, and found the skeleton of a
horse, so we knew that Indians were in the neighbourhood.

THE VOYAGE OF THE BEAGLE 193

On the next morning (21 st) tracks of a party of horse,
and marks left by the trailing of the chuzos, or long spears,
were observed on the ground. It was generally thought
that the Indians had reconnoitred us during the night.
Shortly afterwards we came to a spot where, from the fresh
footsteps of men, children, and horses, it was evident that
the party had crossed the river.

April 22nd. — The country remained the same, and was
extremely uninteresting. The complete similarity of the
productions throughout Patagonia is one of its most strik-
ing characters. The level plains of arid shingle support
the same stunted and dwarf plants; and in the valleys the
same thorn-bearing bushes grow. Everywhere we see the
same birds and insects. Even the very banks of the river
and of the clear streamlets which entered it, were scarcely
enlivened by a brighter tint of green. The curse of sterility
is on the land, and the water flowing over a bed of pebbles
partakes of the same curse. Hence the number of water-
fowl is very scanty; for there is nothing to support life in
the stream of this barren river.

Patagonia, poor as she is in some respects, can however
boast of a greater stock of small rodents1 than perhaps any
other country in the world. Several species of mice are
externally characterized by large thin ears and a very fine
fur. These little animals swarm amongst the thickets in the
valleys, where they cannot for months together taste a drop
of water excepting the dew. They all seem to be cannibals ;
for no sooner was a mouse caught in one of my traps than
it was devoured by others. A small and delicately shaped
fox, which is likewise very abundant, probably derives its
entire support from these small animals. The guanaco is
also in his proper district ; herds of fifty or a hundred were
common; and, as I have stated, we saw one which must
have contained at least five hundred. The puma, with the
condor and other carrion-hawks in its train, follows and
preys upon these animals. The footsteps of the puma were
to be seen almost everywhere on the banks of the river;
and the remains of several guanacos, with their necks

1 The deserts of Syria are characterized, according to Volney (torn. i.
p. 35i). by woody bushes, numerous rats, gazelles and hares. In the land-
Scape of Patagonia, the guanaco replaces the gazelle, and the agouti the hare.

dislocated and bones broken, showed how they had met their
death.

April 24th. — Like the navigators of old when approaching
an unknown land, we examined and watched for the most
trivial sign of a change. The drifted trunk of a tree, or a
boulder of primitive rock, was hailed with joy, as if we had
seen a forest growing on the flanks of the Cordillera. The
top, however, of a heavy bank of clouds, which remained
almost constantly in one position, was the most promising
sign, and eventually turned out a true harbinger. At first the
clouds were mistaken for the mountains themselves, instead
of the masses of vapour condensed by their icy summits.

April 26th. — We this day met with a marked change ii»
the geological structure of the plains. From the first start-
ing I had carefully examined the gravel in the river, and
for the two last days had noticed the presence of a few small
pebbles of a very cellular basalt. These gradually increased
in number and in size, but none were as large as a man's
head. This morning, however, pebbles of the same rock,
but more compact, suddenly became abundant, and in the
course of half an hour we saw, at the distance of five or
six miles, the angular edge of a great basaltic platform.
When we arrived at its base we found the stream bubbling
among the fallen blocks. For the next twenty-eight miles
the river-course was encumbered with these basaltic masses.
Above that limit immense fragments of primitive rocks,
derived from its surrounding boulder- formation, were
equally numerous. None of the fragments of any consider-
able size had been washed more than three or four miles
down the river below their parent-source: considering the
singular rapidity of the great body of water in the Santa
Cruz, and that no still reaches occur in any part, this ex-
ample is a most striking one, of the inefficiency of rivers in
transporting even moderately-sized fragments.

The basalt is only lava, which has flowed beneath the sea ;
but the eruptions must have been on the grandest scale. At
the point where we first met this formation it was 120 feet
in thickness; following up the river course, the surface
imperceptibly rose and the mass became thicker, so that at
forty miles above the first station it was 320 feet thick.

THE VOYAGE OF THE BEAGLE 195

What the thickness may be close to the Cordillera, I have
no means of knowing, but the platform there attains a height
of about three thousand feet above the level of the sea:
we must therefore look to the mountains of that great chain
for its source ; and worthy of such a source are streams that
have flowed over the gently inclined bed of the sea to a
distance of one hundred miles. At the first glance of the
basaltic cliffs on the opposite sides of the valley, it was
evident that the strata once were united. What power, then,
has removed along a whole line of country, a solid mass of
very hard rock, which had an average thickness of nearly
three hundred feet, and a breadth varying from rather less
than two miles to four miles? The river, though it has so
little power in transporting even inconsiderable fragments,
yet in the lapse of ages might produce by its gradual erosion
an effect of which it is difficult to judge the amount. But
in this case, independently of the insignificance of such an
agency, good reasons can be assigned for believing that this
valley was formerly occupied by an arm of the sea. It is
needless in this work to detail the arguments leading to this
conclusion, derived from the form and the nature of the
step-formed terraces on both sides of the valley, from the
manner in which the bottom of the valley near the Andes
expands into a great estuary-like plain with sand-hillocks
on it, and from the occurrence of a few sea-shells lying in
the bed of the river. If I had space I could prove that
South America was formerly here cut off by a strait, joining
the Atlantic and Pacific oceans, like that of Magellan.
But it may yet be asked, how has the solid basalt been
moved? Geologists formerly would have brought into play,
the violent action of some overwhelming debacle ; but in this
case such a supposition would have been quite inadmissible ;
because, the same step-like plains with existing sea-shells
lying on their surface, which front the long line of the Pata-
gonian coast, sweep up on each side of the valley of Santa
Cruz. No possible action of any flood could thus have
modelled the land, either within the valley or along the open
coast; and by the formation of such step-like plains or ter-
races the valley itself had been hollowed out. Although we
know that there are tides, which run within the Narrows

196 CHARLES DARWIN

of the Strait of Magellan at the rate of eight knots an hour,
yet we must confess that it makes the head almost giddy to
reflect on the number of years, century after century, which
the tides, unaided by a heavy surf, must have required to
have corroded so vast an area and thickness of solid basaltic
lava. Nevertheless, we must believe that the strata under-
mined by the waters of this ancient strait, were broken up
into huge fragments, and these lying scattered on the beach,
were reduced first to smaller blocks, then to pebbles and
lastly to the most impalpable mud, which the tides drifted
far into the Eastern or Western Ocean.

With the change in the geological structure of the plains
the character of the landscape likewise altered. While ram-
bling up some of the narrow and rocky defiles, I could almost
have fancied myself transported back again to the barren
valleys of the island of St. Jago. Among the basaltic cliffs,
I found some plants which I had seen nowhere else, but
others I recognised as being wanderers from Tierra del
Fuego. These porous rocks serve as a reservoir for the
scanty rain-water; and consequently on the line where the
igneous and sedimentary formations unite, some small
springs (most rare occurrences in Patagonia) burst forth;
and they could be distinguished at a distance by the circum-
scribed patches of bright green herbage.

April 2fik. — The bed of the river became rather narrower,
and hence the stream more rapid. It here ran at the rate
of six knots an hour. From this cause, and from the many
great angular fragments, tracking the boats became both
dangerous and laborious.

This day I shot a condor. It measured from tip to tip
of the wings, eight and a half feet, and from beak to tail,
four feet. This bird is known to have a wide geographical
range, being found on the west coast of South America,
from the Strait of Magellan along the Cordillera as far as
eight degrees north of the equator. The steep cliff near the
mouth of the Rio Negro is its northern limit on the Pata-
gonian coast; and they have there wandered about four
hundred miles from the great central line of their habita-
tion in the Andes. Further south, among the bold preci-

THE VOYAGE OF THE BEAGLE 197

pices at the head of Port Desire, the condor is not uncom-
mon; yet only a few stragglers occasionally visit the sea-
coast. A line of cliff near the mouth of the Santa Cruz is
frequented by these birds, and about eighty miles up the
river, where the sides of the valley are formed by steep
basaltic precipices, the condor reappears. From these facts,
it seems that the condors require perpendicular cliffs. In
Chile, they haunt, during the greater part of the year, the
lower country near the shores of the Pacific, and at night
several roost together in one tree ; but in the early part of
summer, they retire to the most inaccessible parts of the
inner Cordillera, there to breed in peace.

With respect to their propagation, I was told by the
country people in Chile, that the condor makes no sort of
nest, but in the months of November and December lays
two large white eggs on a shelf of bare rock. It is said that
the young condors cannot fly for an entire year; and long
after they are able, they continue to roost by night, and
hunt by day with their parents. The old birds generally live
in pairs; but among the inland basaltic cliffs of the Santa
Cruz, I found a spot, where scores must usually haunt. On
coming suddenly to the brow of the precipice, it was a grand
spectacle to see between twenty and thirty of these great
birds start heavily from their resting-place, and wheel away
in majestic circles. From the quantity of dung on the rocks,
they must long have frequented this cliff for roosting and
breeding. Having gorged themselves with carrion on the
plains below, they retire to these favourite ledges to digest
their food. From these facts, the condor, like the gallinazo,
must to a certain degree be considered as a gregarious bird.
In this part of the country they live altogether on the guana-
cos which have died a natural death, or as more commonly
happens, have been killed by the pumas. I believe, from
what I saw in Patagonia, that they do not on ordinary occa-
sions extend their daily excursions to any great distance
from their regular sleeping-places.

The condors may oftentimes be seen at a great height,
soaring over a certain spot in the most graceful circles.
On some occasions I am sure that they do this only for
pleasure, but on others, the Chileno countryman tells you

198 CHARLES DARWIN

that they are watching a dying animal, or the puma devour-
ing its prey. If the condors glide down, and then suddenly
all rise together, the Chileno knows that it is the puma
which, watching the carcass, has sprung out to drive away
the robbers. Besides feeding on carrion, the condors fre-
quently attack young goats and lambs; and the shepherd-
dogs are trained, whenever they pass over, to run out, and
looking upwards to bark violently. The Chilenos destroy
and catch numbers. Two methods are used ; one is to place
a carcass on a level piece of ground within an enclosure of
sticks with an opening, and when the condors are gorged,
to gallop up on horseback to the entrance, and thus enclose
them: for when this bird has not space to run, it cannot
give its body sufficient momentum to rise from the ground.
The second method is to mark the trees in which, frequently
to the number of five or six together, they roost, and then
at night to climb up and noose them. They are such heavy
sleepers, as I have myself witnessed, that this is not a diffi-
cult task. At Valparaiso, I have seen a living condor sold
for sixpence, but the common price is eight or ten shillings.
One which I saw brought in, had been tied with rope, and
was much injured; yet, the moment the line was cut by
which its bill was secured, although surrounded by people,
it began ravenously to tear a piece of carrion. In a garden
at the same place, between twenty and thirty were kept alive.
They were fed only once a week, but they appeared in pretty
good health.2 The Chileno countrymen assert that the con-
dor will live, and retain its vigour, between five and six weeks
without eating: I cannot answer for the truth of this, but
it is a cruel experiment, which very likely has been tried.

When an animal is killed in the country, it is well known
that the condors, like other carrion-vultures, soon gain in-
telligence of it, and congregate in an inexplicable manner.
In most cases it must not be overlooked, that the birds
have discovered their prey, and have picked the skeleton
clean, before the flesh is in the least degree tainted. Re-
membering the experiments of M. Audubon, on the little
smelling powers of carrion-hawks, I tried in the above-

* I noticed that several hours before any one of the condors died, all
the lice, with which it was infested, crawled to the outside feathers. I was
assured that this always happened.

THE VOYAGE OF THE BEAGLE 199

mentioned garden the following experiment: the condors
were tied, each by a rope, in a long row at the bottom of a
wall; and having folded up a piece of meat in white paper, I
walked backwards and forwards, carrying it in my hand at
the distance of about three yards from them, but no notice
whatever was taken. I then threw it on the ground, within
one yard of an old male bird ; he looked at it for a moment
with attention, but then regarded it no more. With a stick
I pushed it closer and closer, until at last he touched it with
his beak ; the paper was then instantly torn off with fury,
and at the same moment, every bird in the long row began
struggling and flapping its wings. Under the same circum-
stances, it would have been quite impossible to have deceived
a dog. The evidence in favour of and against the acute
smelling powers of carrion-vultures is singularly balanced.
Professor Owen has demonstrated that the olfactory nerves
of the turkey-buzzard (Cathartes aura) are highly devel-
oped; and on the evening when Mr. Owen's paper was read
at the Zoological Society, it was mentioned by a gentleman
that he had seen the carrion-hawks in the West Indies on
two occasions collect on the roof of a house, when a corpse
had become offensive from not having been buried; in this
case, the intelligence could hardly have been acquired by
sight. On the other hand, besides the experiments of Audu-
bon and that one by myself, Mr. Bachman has tried in the
United States many varied plans, showing that neither the
turkey-buzzard (the species dissected by Professor Owen)
nor the gallinazo find their food by smell. He covered por-
tions of highly-offensive offal with a thin canvas cloth, and
strewed pieces of meat on it: these the carrion-vultures ate
up, and then remained quietly standing, with their beaks
within the eighth of an inch of the putrid mass, without
discovering it. A small rent was made in the canvas, and
the offal was immediately discovered; the canvas was re-
placed by a fresh piece, and meat again put on it, and was
again devoured by the vultures without their discovering
the hidden mass on which they were trampling. These facts
are attested by the signatures of six gentlemen, besides that
of Mr. Bachman.3

Often when lying down to rest on the open plains, on
looking upwards, I have seen carrion-hawks sailing through
the air at a great height. Where the country is level I do
not believe a space of the heavens, of more than fifteen de-
grees above the horizon, is commonly viewed with any at-
tention by a person either walking or on horseback. If such
be the case, and the vulture is on the wing at a height of
between three and four thousand feet, before it could come
within the range of vision, its distance in a straight line
from the beholder's eye, would be rather more than two
British miles. Might it not thus readily be overlooked?
When an animal is killed by the sportsman in a lonely valley,
may he not all the while be watched from above by the
sharp-sighted bird? And will not the manner of its descent
proclaim throughout the district to the whole family of
carrion-feeders, that their prey is at hand?

When the condors are wheeling in a flock round and
round any spot, their flight is beautiful. Except when rising
from the ground, I do not recollect ever having seen one
of these birds flap its wings. Near Lima, I watched several
for nearly half an hour, without once taking off my eyes:
they moved in large curves, sweeping in circles, descending
and ascending without giving a single flap. As they glided
close over my head, I intently watched from an oblique posi-
tion, the outlines of the separate and great terminal feathers
of each wing; and these separate feathers, if there had been
the least vibratory movement, would have appeared as if
blended together; but they were seen distinct against the
blue sky. The head and neck were moved frequently, and
apparently with force; and the extended wings seemed to
form the fulcrum on which the movements of the neck, body,
and tail acted. If the bird wished to descend, the wings
were for a moment collapsed; and when again expanded
with an altered inclination, the momentum gained by the
rapid descent seemed to urge the bird upwards with the
even and steady movement of a paper kite. In the case of
any bird soaring, its motion must be sufficiently rapid so
that the action of the inclined surface of its body on the
atmosphere may counterbalance its gravity. The force to
keep up the momentum of a body moving in a horizontal

THE VOYAGE OF THE BEAGLE 201

plane in the air (in which there is so little friction) cannot
be great, and this force is all that is wanted. The move-
ment of the neck and body of the condor, we must suppose,
is sufficient for this. However this may be, it is truly won-
derful and beautiful to see so great a bird, hour after hour,
without any apparent exertion, wheeling and gliding over
mountain and river.

April zpth. — From some high land we hailed with joy
the white summits of the Cordillera, as they were seen occa-
sionally peeping through their dusky envelope of clouds.
During the few succeeding days we continued to get on
slowly, for we found the river-course very tortuous, and
strewed with immense fragments of various ancient slaty
rocks, and of granite. The plain bordering the valley had
here attained an elevation of about noo feet above the river,
and its character was much altered. The well-rounded peb-
bles of porphyry were mingled with many immense angular
fragments of basalt and of primary rocks. The first of these
erratic boulders which I noticed, was sixty-seven miles dis-
tant from the nearest mountain; another which I measured
was five yards square, and projected five feet above the
gravel. Its edges were so angular, and its size so great, that
I at first mistook it for a rock in situ, and took out my com-
pass to observe the direction of its cleavage. The plain here
was not quite so level as that nearer the coast, but yet it
betrayed no signs of any great violence. Under these cir-
cumstances it is, I believe, quite impossible to explain the
transportal of these gigantic masses of rock so many miles
from their parent-source, on any theory except by that of
floating icebergs.

During the two last days we met with signs of horses, and
with several small articles which had belonged to the Indians
— such as parts of a mantle and a bunch of ostrich feathers —
but they appeared to have been lying long on the ground.
Between the place where the Indians had so lately crossed
the river and this neighbourhood, though so many miles
apart, the country appears to be quite unfrequented. At first,
considering the abundance of the guanacos, I was surprised
at this ; but it is explained by the stony nature of the plains,

202 CHARLES DARWIN

which would soon disable an unshod horse from taking part
in the chase. Nevertheless, in two places in this very central
region, I found small heaps of stones, which I do not think
could have been accidentally thrown together. They were
placed on points, projecting over the edge of the highest lava
cliff, and they resembled, but on a small scale, those near
Port Desire.

May 4th. — Captain Fitz Roy determined to take the boats
no higher. The river had a winding course, and was very
rapid; and the appearance of the country offered no tempta-
tion to proceed any further. Everywhere we met with the
same productions, and the same dreary landscape. We were
now one hundred and forty miles distant from the Atlantic,
and about sixty from the nearest arm of the Pacific. The
valley in this upper part expanded into a wide basin, bounded
on the north and south by the basaltic platforms, and fronted
by the long range of the snow-clad Cordillera. But we
viewed these grand mountains with regret, for we were
obliged to imagine their nature and productions, instead of
standing, as we had hoped, on their summits. Besides the
useless loss of time which an attempt to ascend the river any
higher would have cost us, we had already been for some
days on half allowance of bread. This, although really
enough for reasonable men, was, after a hard day's march,
rather scanty food: a light stomach and an easy digestion
are good things to talk about, but very unpleasant in practice.

$th. — Before sunrise we commenced our descent. We
shot down the stream with great rapidity, generally at the
rate of ten knots an hour. In this one day we effected what
had cost us five-and-a-half hard days' labour in ascending.
On the 8th, we reached the Beagle after our twenty-one days'
expedition. Every one, excepting myself, had cause to be
dissatisfied; but to me the ascent afforded a most interesting
section of the great tertiary formation of Patagonia.

On March ist, 1833," and again on March i6th, 1834, the
Beagle anchored in Berkeley Sound, in East Falkland Island.
This archipelago is situated in nearly the same latitude with
the mouth of the Strait of Magellan; it covers a space of
one hundred and twenty by sixty geographical miles, and is a

THE VOYAGE OF THE BEAGLE 203

little more than half the size of Ireland. After the posses-
sion of these miserable islands had been contested by France,
Spain, and England, they were left uninhabited. The gov-
ernment of Buenos Ayres then sold them to a private indi-
vidual, but likewise used them, as old Spain had done before,
for a penal settlement. England claimed her right and
seized them. The Englishman who was left in charge of
the flag was consequently murdered. A British officer was
next sent, unsupported by any power : and when we arrived,
we found him in charge of a population, of which rather
more than half were runaway rebels and murderers.

The theatre is worthy of the scenes acted on it. An un-
dulating land, with a desolate and wretched aspect, is every-
where covered by a peaty soil and wiry grass, of one mon-
otonous brown colour. Here and there a peak or ridge
of grey quartz rock breaks through the smooth surface.
Every one has heard of the climate of these regions; it
may be compared to that which is experienced at the height
of between one and two thousand feet, on the mountains of
North Wales; having however less sunshine and less frost,
but more wind and rain/

i6th. — I. will now describe a short excursion which I
made round a part of this island. In the morning I started
with six horses and two Gauchos: the latter were capital
men for the purpose, and well accustomed to living on their
own resources. The weather was very boisterous and cold,
with heavy hail-storms. We got on, however, pretty well,
but, except the geology, nothing could be less interesting
than our day's ride. The country is uniformly the same
undulating moorland; the surface being covered by light
brown withered grass and a few very small shrubs, all
springing out of an elastic peaty soil. In the valleys here
and there might be seen a small flock of wild geese, and
everywhere the ground was so soft that the snipe were able
to feed. Besides these two birds there were few others.

* From accounts published since our voyage, and more especially from
several interesting letters from Capt. Sulivan, R.N., employed on the sur-
vey, it appears that we took an exaggerated view of the badness of the
climate of these islands. But when I reflect on the almost universal cover-
ing of peat, and on the fact of wheat seldom ripening here, I can hardly
believe that the climate in summer is so fine and dry as it has lately been
represented.

204 CHARLES DARWIN

There is one main range of hills, nearly two thousand feet
in height, and composed of quartz rock, the rugged and bar-
ren crests of which gave us some trouble to cross. On the
south side we came to the best country for wild cattle; we
met, however, no great number, for they had been lately
much harassed.

In the evening we came across a small herd. One of my
companions, St. Jago by name, soon separated a fat cow;
he threw the bolas, and it struck her legs, but failed in be-
coming entangled. Then dropping his hat to mark the spot
where the balls were left, while at full gallop, he uncoiled
his lazo, and after a most severe chase, again came up to
the cow, and caught her round the horns. The other Gaucho
had gone on ahead with the spare horses, so that St. Jago
had some difficulty in killing the furious beast. He man-
aged to get her on a level piece of ground, by taking advan-
tage of her as often as she rushed at him; and when she
would not move, my horse, from having been trained, would
canter up, and with his chest give her a violent push. But
when on level ground it does not appear an easy job for
one man to kill a beast mad with terror. Nor would it be
so, if the horse, when left to itself without its rider, did
not soon learn, for its own safety, to keep the lazo tight;
so that, if the cow or ox moves forward, the horse moves
just as quickly forward; otherwise, it stands motionless
leaning on one side. This horse, however, was a young
one, and would not stand still, but gave in to the cow as she
struggled. It was admirable to see with what dexterity St.
Jago dodged behind the beast, till at last he contrived to
give the fatal touch to the main tendon of the hind leg;
after which, without much difficulty, he drove his knife
into the head of the spinal marrow, and the cow dropped
as if struck by lightning. He cut off pieces of flesh with
the skin to it, but without any bones, sufficient for our
expedition. We then rode on to our sleeping-place, and
had for supper " carne con cuero," or meat roasted with the
skin on it. This is as superior to common beef as venison
is to mutton. A large circular piece taken from the back
is roasted on the embers with the hide downwards and in
the form of a saucer, so that none of the gravy is lost.

THE VOYAGE OF THE BEAGLE 205

If any worthy alderman had supped with us that evening,
"carne con cuero," without doubt, would soon have been
celebrated in London.

During the night it rained, and the next day (i7th) was
very stormy, with much hail and snow. We rode across the
island to the neck of land which joins the Rincon del Toro
(the great peninsula at the S. W. extremity) to the rest of
the island. From the great number of cows which have
been killed, there is a large proportion of bulls. These wan-
der about single, or two and three together, and are very
savage. I never saw such magnificent beasts; they equalled
in the size of their huge heads and necks the Grecian marble
sculptures. Capt. Sulivan informs me that the hide of an
average-sized bull weighs forty-seven pounds, whereas a
hide of this weight, less thoroughly dried, is considered as
a very heavy one at Monte Video. The young bulls gener-
ally run away? for a short distance; but the old ones do not
stir a step, except to rush at man and horse; and many
horses have been thus killed. An old bull crossed a boggy
stream, and took his stand on the opposite side to us; we
in vain tried to drive him away, and failing, were obliged
to make a large circuit. The Gauchos in revenge deter-
mined to emasculate him and render him for the future
harmless. It was very interesting to see how art completely
mastered force. One lazo was thrown over his horns as he
rushed at the horse, and another round his hind legs: in a
minute the monster was stretched powerless on the ground.
After the lazo has once been drawn tightly round the horns
of a furious animal, it does not at first appear an easy thing
to disengage it again without killing the beast: nor, I ap-
prehend, would it be so if the man was by himself. By the
aid, however, of a second person throwing his lazo so as to
catch both hind legs, it is quickly managed: for the animal,
as long as its hind legs are kept outstretched, is quite help-
less, and the first man can with his hands loosen his lazo
from the horns, and then quietly mount his horse; but the
moment the second man, by backing ever so little, relaxes
the strain, the lazo slips off the legs of the struggling beast,
which then rises free, shakes himself, and vainly rushes at
his antagonist.

206 CHARLES DARWIN

During our whole ride we saw only one troop of wild
horses. These animals, as well as the cattle, were introduced
by the French in 1764, since which time both have greatly
increased. It is a curious fact, that the horses have never
left the eastern end of the island, although there is no natu-
ral boundary to prevent them from roaming, and that part
of the island is not more tempting than the rest. The Gau-
chos whom I asked, though asserting this to be the case,
were unable to account for it, except from the strong attach-
ment which horses have to any locality to which they are
accustomed. Considering that the island does not appear
fully stocked, and that there are no beasts of prey, I was
particularly curious to know what has checked their origi-
nally rapid increase. That in a limited island some check
would sooner or later supervene, is inevitable; but why has
the increase of the horse been checked sooner than that of
the cattle? Capt. Sulivan has taken much pains for me
in this inquiry. The Gauchos employed here attribute it
chiefly to the stallions constantly roaming from place to
place, and compelling the mares to accompany them, whether
or not the young foals are able to follow. One Gaucho told
Capt. Sulivan that he had watched a stallion for a whole
hour, violently kicking and biting a mare till he forced
her to leave her foal to its fate. Capt. Sulivan can so far
corroborate this curious account, that he has several times
found young foals dead, whereas he has never found a dead
calf. Moreover, the dead bodies of full-grown horses are
more frequently found, as if more subject to disease or
accidents, than those of the cattle. From the softness of
the ground their hoofs often grow irregularly to a great
length, and this causes lameness. The predominant colours
are roan and iron-grey. All the horses bred here, both tame
and wild, are rather small-sized, though generally in good
condition; and they have lost so much strength, that they
are unfit to be used in taking wild cattle with the lazo: in
consequence, it is necessary to go to the great expense of
importing fresh horses from the Plata. At some future
period the southern hemisphere probably will have its breed
of Falkland ponies, as the northern has its Shetland breed.

The cattle, instead of having degenerated like the horse,

THE VOYAGE OF THE BEAGLE 207

seem, as before remarked, to have increased in size; and
they are much more numerous than the horses. Capt. Suli-
van informs me that they vary much less in the general
form of their bodies and in the shape of their horns than
English cattle. In colour they differ much; and it is a re-
markable circumstance, that in different parts of this one
small island, different colours predominate. Round Mount
Usborne, at a height of from 1000 to 1500 feet above the sea,
about half of some of the herds are mouse or lead-coloured,
a tint which is not common in other parts of the island.
Near Port Pleasant dark brown prevails, whereas south of
Choiseul Sound (which almost divides the island into two
parts), white beasts with black heads and feet are the most
common: in all parts black, and some spotted animals may
be observed. Capt. Sulivan remarks, that the difference in
the prevailing colours was so obvious, that in looking for
the herds near Port Pleasant, they appeared from a long
distance like black spots, whilst south of Choiseul Sound
they appeared like white spots on the hill-sides. Capt. Suli-
van thinks that the herds do not mingle ; and it is a singular
fact, that the mouse-coloured cattle, though living on the
high land, calve about a month earlier in the season than
the other coloured beasts on the lower land. It is inter-
esting thus to find the once domesticated cattle breaking
into three colours, of which some one colour would in all
probability ultimately prevail over the others, if the herds
were left undisturbed for the next several centuries.

The rabbit is another animal which has been introduced,
and has succeeded very well ; so that they abound over large
parts of the island. Yet, like the horses, they are confined
within certain limits; for they have not crossed the central
chain of hills, nor would they have extended even so far as
its base, if, as the Gauchos informed me, small colonies had
not been carried there. I should not have supposed that
these animals, natives of northern Africa, could have existed
in a climate so humid as this, and which enjoys so little
sunshine that even wheat ripens only occasionally. It is
asserted that in Sweden, which any one would have thought
a more favourable climate, the rabbit cannot live out of
doors. The first few pairs, moreover, had here to contend

208 CHARLES DARWIN

against pre-existing enemies, in the fox and some large
hawks. The French naturalists have considered the black
variety a distinct species, and called it Lepus Magellanicus.5
They imagined that Magellan, when talking of an animal
under the name of "conejos" in the Strait of Magellan,
referred to this species ; but he was alluding to a small cavy,
which to this day is thus called by the Spaniards. The
Gauchos laughed at the idea of the black kind being differ-
ent from the grey, and they said that at all events it had
not extended its range any further than the grey kind; that
the two were never found separate; and that they readily
bred together, and produced piebald offspring. Of the latter
I now possess a specimen, and it is marked about the head
differently from the French specific description. This cir-
cumstance shows how cautious naturalists should be in
making species; for even Cuvier, on looking at the skull
of one of these rabbits, thought it was probably distinct !

The only quadruped native to the island9 is a large wolf-
like fox (Canis antarcticus), which is common to both East
and West Falkland. I have no doubt it is a peculiar species,
and confined to this archipelago; because many sealers,
Gauchos, and Indians, who have visited these islands, all
maintain that no such animal is found in any part of South
America.

Molina, from a similarity in habits, thought that this
was the same with his "culpeu;"7 but I have seen both,
and they are quite distinct. These wolves are well known,
from Byron's account of their tameness and curiosity, which
the sailors, who ran into the water to avoid them, mistook
for fierceness. To this day their manners remain the same.
They have been observed to enter a tent, and actually pull
some meat from beneath the head of a sleeping seaman. The

5 Lesson's Zoology of the Voyage of the Coquille, torn. i. p. 168. All the
early voyagers, and especially Bougainville, distinctly state that_ the wolf-
like fox was the only native animal on the island. The distinction of the
rabbit as a species, is taken from peculiarities in the fur, from the shape of
the head, and from the shortness of the ears. I may here observe that the
difference between the Irish and English hare rests upon nearly similar
characters, only more strongly marked.

• I have reason, however, to suspect that there is a field-mouse. The
common European rat and mouse have roamed far from the habitations of
the settlers. The common hog has also run wild on one islet; all are of a
black colour: the boars are very fierce, and have great tusks.

7 The " culpeu " is the Canis Magellanicus brought home by Captain King
from the Strait of Magellan. It is common in Chile.

209

Gauchos also have frequently in the evening killed them,
by holding out a piece of meat in one hand, and in the other
a knife ready to stick them. As far. as I am aware, there
is no other instance in any part of the world, of so small
a mass of broken land, distant from a continent, possessing
so large an aboriginal quadruped peculiar to itself. Their
numbers have rapidly decreased; they are already banished
from that half of the island which lies to the eastward of
the neck of land between St. Salvador Bay and Berkeley
Sound. Within a very few years after these islands shall
have become regularly settled, in all probability this fox
will be classed with the dodo, as an animal which has per-
ished from the face of the earth.

At night (i7th) we slept on the neck of land at the head
of Choiseul Sound, which forms the south-west peninsula.
The valley was pretty well sheltered from the cold wind;
but there was very little brushwood for fuel. The Gauchos,
however, soon found what, to my great surprise, made nearly
as hot a fire as coals; this was the skeleton of a bullock lately
killed, from which the flesh had been picked by the carrion-
hawks. They told me that in winter they often killed a
beast, cleaned the flesh from the bones with their knives,
and then with these same bones roasted the meat for their
suppers.

i8th. — It rained during nearly the whole day. At night
we managed, however, with our saddle-cloths to keep our-
selves pretty well dry and warm; but the ground on which
we slept was on each occasion nearly in the state of a bog,
and there was not a dry spot to sit down on after our day's
ride. I have in another part stated how singular it is that
there should be absolutely no trees on these islands, although
Tierra del Fuego is covered by one large forest. The
largest bush in the island (belonging to the family of Com-
positae) is scarcely so tall as our gorse. The best fuel is
afforded by a green little bush about the size of common
heath, which has the useful property of burning while fresh
and green. It was very surprising to see the Gauchos, in
the midst of rain and everything soaking wet, with nothing
more than a tinder-box and a piece of rag, immediately make
a fire. They sought beneath the tufts of grass and bushes

210 CHARLES DARWIN

for a few dry twigs, and these they rubbed into fibres; then
surrounding them with coarser twigs, something like a bird's
nest, they put the rag with its spark of fire in the middle
and covered it up. The nest being then held up to the
wind, by degrees it smoked more and more, and at last
burst out in flames. I do not think any other method would
have had a chance of succeeding with such damp materials.

ipth. — Each morning, from not having ridden for some
time previously, I was very stiff. I was surprised to hear
the Gauchos, who have from infancy almost lived on horse-
back, say thai, under similar circumstances, they always
suffer. St. Jago told me, that having been confined for three
months by illness, he went out hunting wild cattle, and in
consequence, for the next two days, his thighs were so stiff
that he was obliged to lie in bed. This shows that the Gau-
chos, although they do not appear to do so, yet really must
exert much muscular effort in riding. The hunting wild
cattle, in a country so difficult to pass as this is on account
of the swampy ground, must be very hard work. The
Gauchos say they often pass at full speed over ground which
would be impassable at a slower pace; in the same manner
as a man is able to skate over thin ice. When hunting, the
party endeavours to get as close as possible to the herd with-
out being discovered. Each man carries four or five pair of
the bolas; these he throws one after the other at as many
cattle, which, when once entangled, are left for some days,
till they become a little exhausted by hunger and struggling.
They are then let free and driven towards a small herd of
tame animals, which have been brought to the spot on pur-
pose. From their previous treatment, being too much ter-
rified to leave the herd, they are easily driven, if their
strength last out, to the settlement.

The weather continued so very bad that we determined
to make a push, and try to reach the vessel before night.
From the quantity of rain which had fallen, the surface
of the whole country was swampy. I suppose my horse fell
at least a dozen times, and sometimes the whole six horses
were floundering in the mud together. All the little streams
are bordered by soft peat, which makes it very difficult for
the horses to leap them without falling. To complete our

THE VOYAGE OF THE BEAGLE 211

discomforts we were obliged to cross the head of a creek
of the sea, in which the water was as high as our horses'
backs; and the little waves, owing to the violence of the
wind, broke over us, and made us very wet and cold. Even
the iron-framed Gauchos professed themselves glad when
they reached the settlement, after our little excursion.

The geological structure of these islands is in most
respects simple. The lower country consists of clay-slate
and sandstone, containing fossils, very closely related to, but
not identical with, those found in the Silurian formations
of Europe; the hills are formed of white granular quartz
rock. The strata of the latter are frequently arched with
perfect symmetry, and the appearance of some of the masses
is in consequence most singular. Pernety8 has devoted
several pages to the description of a Hill of Ruins, the
successive strata of which he has justly compared to the
seats of an amphitheatre. The quartz rock must have been
quite pasty when it underwent such remarkable flexures
without being shattered into fragments. As the quartz
insensibly passes into the sandstone, it seems probable that
the former owes its origin to the sandstone having been
heated to such a degree that it became viscid, and upon cool-
ing crystallized. While in the soft state it must have been
pushed up through the overlying beds.

In many parts of the island the bottoms of the valleys are
covered in an extraordinary manner by myriads of great
loose angular fragments of the quartz rock, forming " streams
of stones." These have been mentioned with surprise by
every voyager since the time of Pernety. The blocks are
not waterworn, their angles being only a little blunted; they
vary in size from one or two feet in diameter to ten, or even
more than twenty times as much. They are not thrown
together into irregular piles, but are spread out into level
sheets or great streams. It is not possible to ascertain their
thickness, but the water of small streamlets can be heard
trickling through the stones many feet below the surface.
The actual depth is probably great, because the crevices
between the lower fragments must long ago have been filled

up with sand. The width of these sheets of stones varies
from a few hundred feet to a mile; but the peaty soil daily
encroaches on the borders, and even forms islets wherever
a few fragments happen to lie close together. In a valley
south of Berkeley Sound, which some of our party called
the " great valley of fragments," it was necessary to cross
an uninterrupted band half a mile wide, by jumping from
one pointed stone to another. So large were the fragments,
that being overtaken by a shower of rain, I readily found
shelter beneath one of them.

Their little inclination is the most remarkable circum-
stance in these " streams of stones." On the hill-sides I have
seen them sloping at an angle of ten degrees with the horizon ;
but in some of the level, broad-bottomed valleys, the inclina-
tion is only just sufficient to be clearly perceived. On so
rugged a surface there was no means of measuring the
angle ; but to give a common illustration, I may say that the
slope would not have checked the speed of an English mail-
coach. In some places, a continuous stream of these frag-
ments followed up the course of a valley, and even
extended to the very crest of the hill. On these crests huge
masses, exceeding in dimensions any small building, seemed
to stand arrested in their headlong course: there, also, the
curved strata of the archways lay piled on each other, like
the ruins of some vast and ancient cathedral. In endeavour-
ing to describe these scenes of violence one is tempted to pass
from one simile to another. We may imagine that streams
of white lava had flowed from many parts of the mountains
into the lower country, and that when solidified they had been
rent by some enormous convulsion into myriads of frag-
ments. The expression " streams of stones," which immedi-
ately occurred to every one, conveys the same idea. These
scenes are on the spot rendered more striking by the con-
trast of the low rounded forms of the neighbouring hills.

I was interested by finding on the highest peak of one
range (about 700 feet above the sea) a great arched frag-
ment, lying on its convex side, or back downwards. Must
we believe that it was fairly pitched up in the air, and thus
turned? Or, with more probability, that there existed for-
merly a part of the same range more elevated than the point

THE VOYAGE OF THE BEAGLE 213

on which this monument of a great convulsion of nature now
lies. As the fragments in the valleys are neither rounded
nor the crevices filled up with sand, we must infer that the
period of violence was subsequent to the land having been
raised above the waters of the sea. In a transverse section
within these valleys, the bottom is nearly level, or rises but
very little towards either side. Hence the fragments appear
to have travelled from the head of the valley; but in reality
it seems more probable that they have been hurled down from
the nearest slopes; and that since, by a vibratory movement
of overwhelming force," the fragments have been levelled
into one continuous sheet. If during the earthquake10 which
in 1835 overthrew Concepcion, in Chile, it was thought won-
derful that small bodies should have been pitched a few
inches from the ground, what must we say to a movement
which has caused fragments many tons in weight, to move
onwards like so much sand on a vibrating board, and find
their level? I have seen, in the Cordillera of the Andes, the
evident marks where stupendous mountains have been broken
into pieces like so much thin crust, and the strata thrown on
their vertical edges; but never did any scene, like these
" streams of stones," so forcibly convey to my mind the idea
of a convulsion, of which in historical records we might in
vain seek for any counterpart : yet the progress of knowledge
will probably some day give a simple explanation of this
phenomenon, as it already has of the so long-thought inexpli-
cable transportal of the erratic boulders, which are strewed
over the plains of Europe.

I have little to remark on the zoology of these islands. I
have before described the carrion-vulture of Polyborus.
There are some other hawks, owls, and a few small land-
birds. The water-fowl are particularly numerous, and they
must formerly, from the accounts of the old navigators,
have been much more so. One day I observed a cormorant
playing with a fish which it had caught. Eight times suc-

me that, during the several years he had resided on these islands, he had

214 CHARLES DARWIN

cessively the bird let its prey go, then dived after it, and
although in deep water, brought it each time to the surface.
In the Zoological Gardens I have seen the otter treat a fish
in the same manner, much as a cat does a mouse: I do not
know of any other instance where dame Nature appears so
wilfully cruel. Another day, having placed myself between
a penguin (Aptenodytes demersa) and the water, I was much
amused by watching its habits. It was a brave bird ; and till
reaching the sea, it regularly fought and drove me backwards.
Nothing less than heavy blows would have stopped him ; every
inch he gained he firmly kept, standing close before me erect
and determined. When thus opposed he continually rolled
his head from side to side, in a very odd manner, as if the
power of distinct vision lay only in the anterior and basal
part of each eye. This bird is commonly called the jackass
penguin, from its habit, while on shore, of throwing its head
backwards, and making a loud strange noise, very like the
braying of an ass ; but while at sea, and undisturbed, its note
is very deep and solemn, and is often heard in the night-time.
In diving, its little wings are used as fins ; but on the land, as
front legs. When crawling, it may be said on four legs,
through the tussocks or on the side of a grassy cliff, it moves
so very quickly that it might easily be mistaken for a quadru-
ped. When at sea and fishing, it comes to the surface for
the purpose of breathing with such a spring, and dives again
so instantaneously, that I defy any one at first sight to be
sure that it was not a fish leaping for sport.

Two kinds of geese frequent the Falklands. The upland
species (Anas Magellanica) is common, in pairs and in small
flocks, throughout the island. They do not migrate, but build
on the small outlying islets. This is supposed to be from
fear of the foxes: and it is perhaps from the same cause
that these birds, though very tame by day, are shy and wild
in the dusk of the evening. They live entirely on vegetable
matter.

The rock-goose, so called from living exclusively on the
sea-beach (Anas antarctica), is common both here and on
the west coast of America, as far north as Chile. In the deep
and retired channels of Tierra del Fuego, the snow-white
gander, invariably accompanied by his darker consort, and

THE VOYAGE OF THE BEAGLE 215

standing close by each other on some distant rocky point, is
a common feature in the landscape.

In these islands a great loggerheaded duck or goose (Anas
brachyptera), which sometimes weighs twenty-two pounds,
is very abundant. These birds were in former days called,
from their extraordinary manner of paddling and splashing
upon the water, race-horses ; but now they are named, much
more appropriately, steamers. Their wings are too small and
weak to allow of flight, but by their aid, partly swimming and
partly flapping the surface of the water, they move very
quickly. The manner is something like that by which the
common house-duck escapes when pursued by a dog; but I
am nearly sure that the steamer moves its wings alternately,
instead of both together, as in other birds. These clumsy,
loggerheaded ducks make such a noise and splashing, that the
effect is exceedingly curious.

Thus we find in South America three birds which use their
wings for other purposes besides flight ; the penguins as fins,
the steamer as paddles, and the ostrich as sails: and the
Apteryz of New Zealand, as well as its gigantic extinct pro-
totype the Deinornis, possess only rudimentary representa-
tives of wings. The steamer is able to dive only to a very
short distance. It feeds entirely on shell-fish from the kelp
and tidal rocks : hence the beak and head, for the purpose of
breaking them, are surprisingly heavy and strong: the head
is so strong that I have scarcely been able to fracture it with
my geological hammer ; and all our sportsmen soon discov-
ered how tenacious these birds were of life. When in the
evening pluming themselves in a flock, they make the same
odd mixture of sounds which bull-frogs do within the tropics.

In Tierra del Fuego, as well as in the Falkland Islands, I
made many observations on the lower marine animals," but

11 1 was surprised to find, on counting the eggs of a large white Doris
(this sea-slug was three and a half inches long), how extraordinarily nu-
merous they were. From two to five eggs (each three-thousandths of an
inch in diameter) were contained in a spherical little case. These were
arranged two deep in transverse rows forming a ribbon. The ribbon
adhered by its edge to the rock in an oval spire. One which I found,
measured nearly twenty inches in length and half in breadth. By count-
ing how many balls were contained in a tenth of an inch in the row, and
how many rows in an equal length of the ribbon, on the most moderate com-
putation there were six hundred thousand eggs. Yet this Doris was certainly

216 CHARLES DARWIN

they are of little general interest. I will mention only one
class of facts, relating to certain zoophytes in the more highly
organized division of that class. Several genera (Flustra,
Eschara, Cellaria, Crisia, and others) agree in having singu-
lar moveable organs (like those of Flustra avicularia, found
in the European seas) attached to their cells. The organ, in
the greater number of cases, very closely resembles the head
of a vulture; but the lower mandible can be opened much
wider than in a real bird's beak. The head itself possesses
considerable powers of movement, by means of a short neck.
In one zoophyte the head itself was fixed, but the lower jaw
free : in another it was replaced by a triangular hood, with a
beautifully-fitted trap-door, which evidently answered to the
lower mandible. In the greater number of species, each cell
was provided with one head, but in others each cell had two.

The young cells at the end of the branches of these coral-
lines contain quite immature polypi, yet the vulture-heads
attached to them, though small, are in every respect perfect.
When the polypus was removed by a needle from any of the
cells, these organs did not appear in the least affected. When
one of the vulture-like heads was cut off from the cell, the
lower mandible retained its power of opening and closing.
Perhaps the most singular part of their structure is, that
when there were more than two rows of cells on a branch,
the central cells were furnished with these appendages, of
only one-fourth the size of the outside ones. Their move-
ments varied according to the species; but in some I never
saw the least motion; while others, with the lower mandible
generally wide open, oscillated backwards and forwards at
the rate of about five seconds each turn; others moved rap-
idly and by starts. When touched with a needle, the beak
generally seized the point so firmly, that the whole branch
might be shaken.

These bodies have no relation whatever with the produc-
tion of the eggs or gemmules, as they are formed before the
young polypi appear in the cells at the end of the growing
branches; as they move independently of the polypi, and do
not appear to be in any way connected with them; and as

not very common; although I was often searching under the stones, I saw
only seven individuals. No fallacy is more common with naturalists, than
that the numbers of an individual species depend on its powers of propagation.

THE VOYAGE OF THE BEAGLE 217

they differ in size on the outer and inner rows of cells, I have
little doubt, that in their functions, they are related rather
to the horny axis of the branches than to the polypi in the
cells. The fleshy appendage at the lower extremity of the
sea-pen (described at Bahia Blanca) also forms part of the
zoophyte, as a whole, in the same manner as the roots of a
tree form part of the whole tree, and not of the individual
leaf or flower-buds.

In another elegant little coralline (Crisia?), each cell was
furnished with a long-toothed bristle, which had the power
of moving quickly. Each of these bristles and each of the
vulture-like heads generally moved quite independently of
the others, but sometimes all on both sides of a branch, some-
times only those on one side, moved together coinstantane-
ously; sometimes each moved in regular order one after
another. In these actions we apparently behold as perfect a
transmission of will in the zoophyte, though composed of
thousands of distinct polypi, as in any single animal. The
case, indeed, is not different from that of the sea-pens, which,
when touched, drew themselves into the sand on the coast of
Bahia Blanca. I will state one other instance of uniform
action, though of a very different nature, in a zoophyte
closely allied to Clytia, and therefore very simply organized.
Having kept a large tuft of it in a basin of salt-water, when
it was dark I found that as often as I rubbed any part of a
branch, the whole became strongly phosphorescent with a
green light: I do not think I ever saw any object more beau-
tifully so. But the remarkable circumstance was, that the
flashes of light always proceeded up the branches, from the
base towards the extremities.

The examination of these compound animals was always
very interesting to me. What can be more remarkable than
to see a plant-like body producing an egg, capable of swim-
ming about and of choosing a proper place to adhere to,
which then sprouts into branches, each crowded with innu-
merable distinct animals, often of complicated organizations ?
The branches, moreover, as we have just seen, sometimes
possess organs capable of movement and independent of the
polypi. Surprising as this union of separate individuals in a
common stock must always appear, every tree displays the

218 CHARLES DARWIN

same fact, for buds must be considered as individual plants.
It is, however, natural to consider a polypus, furnished with
a mouth, intestines, and other organs, as a distinct individual,
whereas the individuality of a leaf-bud is not easily realised ;
so that the union of separate individuals in a common body
is more striking in a coralline than in a tree. Our concep-
tion of a compound animal, where in some respects the indi-
viduality of each is not completed, may be aided, by reflecting
on the production of two distinct creatures by bisecting a
single one with a knife, or where Nature herself performs
the task of bisection. We may consider the polypi in a
zoophyte, or the buds in a tree, as cases where the division
of the individual has not been completely effected. Certainly
in the case of trees, and judging from analogy in that of
corallines, the individuals propagated by buds seem more
intimately related to each other, than eggs or seeds are to
their parents. It seems now pretty well established that
plants propagated by buds all partake of a common duration
of life; and it is familiar to every one, what singular and
numerous peculiarities are transmitted with certainty, by
buds, layers, and grafts, which by seminal propagation never
or only casually reappear.

TT^ECEMBER i?th, /S^.— Having now finished with
i i Patagonia and the Falkland Islands, I will describe
our first arrival in Tierra del Fuego. A little after
noon we doubled Cape St. Diego, and entered the famous
strait of Le Maire. We kept close to the Fuegian shore, but
the outline of the rugged, inhospitable Statenland was visible
amidst the clouds. In the afternoon we anchored in the Bay
of Good Success. While entering we were saluted in a man-
ner becoming the inhabitants of this savage land. A group
of Fuegians partly concealed by the entangled forest, were
perched on a wild point overhanging the sea; and as we
passed by, they sprang up and waving their tattered cloaks
sent forth a loud and sonorous shout. The savages followed
the ship, and just before dark we saw their fire, and again
heard their wild cry. The harbour consists of a fine piece
of water half surrounded by low rounded mountains of clay-
slate, which are covered to the water's edge by one dense
gloomy forest. A single glance at the landscape was suf-
ficient to show me how widely different it was from anything
I had ever beheld. At night it blew a gale of wind, and
heavy squalls from the mountains swept past us. It would
have been a bad time out at sea, and we, as well as others,
may call this Good Success Bay.

In the morning the Captain sent a party to communicate
with the Fuegians. When we came within hail, one of the

219

220 CHARLES DARWIN

four natives who were present advanced to receive us, and
began to shout most vehemently, wishing to direct us where
to land. When we were on shore the party looked rather
alarmed, but continued talking and making gestures with
great rapidity. It was without exception the most curious
and interesting spectacle I ever beheld: I could not have
believed how wide was the difference between savage and
civilized man : it is greater than between a wild and domesti-
cated animal, inasmuch as in man there is a greater power
of improvement. The chief spokesman was old, and
appeared to be the head of the family ; the three others were
powerful young men, about six feet high. The women and
children had been sent away. These Fuegians are a very
different race from the stunted, miserable wretches farther
westward; and they seem closely allied to the famous Pata-
gonians of the Strait of Magellan. Their only garment con-
sists of a mantle made of guanaco skin, with the wool out-
side : this they wear just thrown over their shoulders, leaving
their persons as often exposed as covered. Their skin is of
a dirty coppery-red colour.

The old man had a fillet of white feathers tied round his
head, which partly confined his black, coarse, and entangled
hair. His face was crossed by two broad transverse bars;
one, painted bright red, reached from ear to ear and included
the upper lip; the other, white like chalk, extended above
and parallel to the first, so that even his eyelids were thus
coloured. The other two men were ornamented by streaks
of black powder, made of charcoal. The party altogether
closely resembled the devils which come on the stage in plays
like Der Freischutz.

Their very attitudes were abject, and the expression of
their countenances distrustful, surprised, and startled. After
we had presented them with some scarlet cloth, which they
immediately tied round their necks, they became good friends.
This was shown by the old man patting our breasts,
and making a chuckling kind of noise, as people do when
feeding chickens. I walked with the old man, and this dem-
onstration of friendship was repeated several times; it was
concluded by three hard slaps, which were given me on the
breast and back at the same time. He then bared his bosom

THE VOYAGE OF THE BEAGLE 221

for me to return the compliment, which being done, he
seemed highly pleased. The language of these people,
according to our notions, scarcely deserves to be called artic-
ulate. Captain Cook has compared it to a man clearing his
throat, but certainly no European ever cleared his throat
with so many hoarse, guttural, and clicking sounds.

They are excellent mimics: as often as we coughed or
yawned, or made any odd motion, they immediately imitated
us. Some of our party began to squint and look awry; but
one of the young Fuegians (whose whole face was painted
black, excepting a white band across his eyes) succeeded in
making far more hideous grimaces. They could repeat with
perfect correctness each word in any sentence we addressed
them, and they remembered such words for some time. Yet
we Europeans all know how difficult it is to distinguish
apart the sounds in a foreign language. Which of us, for in-
stance, could follow an American Indian through a sentence
of more than three words ? All savages appear to possess, to
an uncommon degree, this power of mimicry. I was told,
almost in the same words, of the same ludicrous habit among
the Caffres ; the Australians, likewise, have long been notori-
ous for being able to imitate and describe the gait of any
man, so that he may be recognized. How can this faculty be
explained? is it a consequence of the more practised habits
of perception and keener senses, common to all men in a
savage state, as compared with those long civilized?

When a song was struck up by our party, I thought the
Fuegians would have fallen down with astonishment. With
equal surprise they viewed our dancing; but one of the
young men, when asked, had no objection to a little waltzing.
Little accustomed to Europeans as they appeared to be, yet
they knew and dreaded our fire-arms; nothing would tempt
them to take a gun in their hands. They begged for knives,
calling them by the Spanish word "cuchilla." They ex-
plained also what they wanted, by acting as if they had a
piece of blubber in their mouth, and then pretending to cut
instead of tear it.

I have not as yet noticed the Fuegians whom we had on
board. During the former voyage of the Adventure and
Beagle in 1826 to 1830, Captain Fitz Roy seized on a party

222 CHARLES DARWIN

of natives, as hostages for the loss of a boat, which had
been stolen, to the great jeopardy of a party employed on
the survey; and some of these natives, as well as a child
whom he bought for a pearl-button, he took with him to
England, determining to educate them and instruct them in
religion at his own expense. To settle these natives in their
own country, was one chief inducement to Captain Fitz Roy
to undertake our present voyage; and before the Admiralty
had resolved to send out this expedition, Captain Fitz Roy
had generously chartered a vessel, and would himself have
taken them back. The natives were accompanied by a mis-
sionary, R. Matthews ; of whom and of the natives, Captain
Fitz Roy has published a full and excellent account. Two
men, one of whom died in England of the small-pox, a boy
and a little girl, were originally taken ; and we had now on
board, York Minster, Jemmy Button (whose name expresses
his purchase-money), and Fuegia Basket. York Minster
was a full-grown, short, thick, powerful man : his disposition
was reserved, taciturn, morose, and when excited violently
passionate; his affections were very strong towards a few
friends on board; his intellect good. Jemmy Button was a
universal favourite, but likewise passionate; the expression
of his face at once showed his nice disposition. He was
merry and often laughed, and was remarkably sympathetic
with any one in pain : when the water was rough, I was often
a little searsick, and he used to come to me and say in a
plaintive voice, " Poor, poor fellow ! " but the notion, after
his aquatic life, of a man being sea-sick, was too ludicrous,
and he was generally obliged to turn on one side to hide a
smile or laugh, and then he would repeat his " Poor, poor
fellow! " He was of a patriotic disposition; and he liked to
praise his own tribe and country, in which he truly said there
were " plenty of trees," and he abused all the other tribes :
he stoutly declared that there was no Devil in his land.
Jemmy was short, thick, and fat, but vain of his personal
appearance; he used always to wear gloves, his hair was
neatly cut, and he was distressed if his well-polished shoes
were dirtied. He was fond of admiring himself in a looking
glass; and a merry-faced little Indian boy from the Rio
Negro, whom we had for some months on board, soon per-

THE VOYAGE OF THE BEAGLE 228

ceived this, and used to mock him : Jemmy, who was always
rather jealous of the attention paid to this little boy, did not
at all like this, and used to say, with rather a contemptuous
twist of his head, " Too much skylark." It seems yet wonder-
ful to me, when I think over all his many good qualities,
that he should have been of the same race, and doubtless
partaken of the same character, with the miserable, degraded
savages whom we first met here. Lastly, Fuegia Basket was
a nice, modest, reserved young girl, with a rather pleasing but
sometimes sullen expression, and very quick in learning any-
thing, especially languages. This she showed in picking up
some Portuguese and Spanish, when left on shore for only
a short time at Rio de Janeiro and Monte Video, and in her
knowledge of English. York Minster was very jealous of
any attention paid to her; for it was clear he determined to
marry her as soon as they were settled on shore.

Although all three could both speak and understand a
good deal of English, it was singularly difficult to obtain
much information from them, concerning the habits of their
countrymen; this was partly owing to their apparent diffi-
culty in understanding the simplest alternative. Every one
accustomed to very young children, knows how seldom one
can get an answer even to so simple a question as whether a
thing is black or white; the idea of black or white seems
alternately to fill their minds. So it was with these Fuegians,
and hence it was generally impossible to find out, by cross-
questioning, whether one had rightly understood anything
which they had asserted. Their sight was remarkably acute ;
it is well known that sailors, from long practice, can make
out a distant object much better than a landsman; but both
York and Jemmy were much superior to any sailor on board :
several times they have declared what some distant object
has been, and though doubted by every one, they have proved
right, when it has been examined through a telescope. They
were quite conscious of this power; and Jemmy, when he
had any little quarrel with the officer on watch, would say,
" Me see ship, me no tell."

It was interesting to watch the conduct of the savages,
when we landed, towards Jemmy Button: they immediately
perceived the difference between him and ourselves, and held

224 CHARLES DARWIN

much conversation one with another on the subject. The
old man addressed a long harangue to Jemmy, which it
seems was to invite him to stay with them. But Jemmy
understood very little of their language, and was, moreover,
thoroughly ashamed of his countrymen. When York Min-
ster afterwards came on shore, they noticed him in the
same way, and told him he ought to shave; yet he had not
twenty dwarf hairs on his face, whilst we all wore our un-
trimmed beards. They examined the colour of his skin, and
compared it with ours. One of our arms being bared, they
expressed the liveliest surprise and admiration at its white-
ness, just in the same way in which I have seen the ourang-
outang do at the Zoological Gardens. We thought that they
mistook two or three of the officers, who were rather shorter
and fairer, though adorned with large beards, for the ladies
of our party. The tallest amongst the Fuegians was evi-
dently much pleased at his height being noticed. When
placed back to back with the tallest of the boat's crew, he
tried his best to edge on higher ground, and to stand on
tiptoe. He opened his mouth to show his teeth, and turned
his face for a side view; and all this was done with such
alacrity, that I dare say he thought himself the handsomest
man in Tierra del Fuego. After our first feeling of grave
astonishment was over, nothing could be more ludicrous
than the odd mixture of surprise and imitation which these
savages every moment exhibited.

The next day I attempted to penetrate some way into the
country. Tierra del Fuego may be described as a mountain-
ous land, partly submerged in the sea, so that deep inlets
and bays occupy the place where valleys should exist. The
mountain sides, except on the exposed western coast, are
covered from the water's edge upwards by one great forest.
The trees reach to an elevation of between 1000 and 1500
feet, and are succeeded by a band of peat, with minute alpine
plants; and this again is succeeded by the line of perpetual
snow, which, according to Captain King, in the Strait of
Magellan descends to between 3000 and 4000 feet To find
an acre of level land in any part of the country is most rare.
I recollect only one little flat piece near Port Famine, and

THE VOYAGE OF THE BEAGLE 225

another of rather larger extent near Goeree Road. In both
places, and everywhere else, the surface is covered by a
thick bed of swampy peat. Even within the forest, the
ground is concealed by a mass of slowly putrefying vegetable
matter, which, from being soaked with water, yields to the
foot.

Finding it nearly hopeless to push my way through the
wood, I followed the course of a mountain torrent. At first,
from the waterfalls and number of dead trees, I could hardly
crawl along; but the bed of the stream soon became a little
more open, from the floods having swept the sides. I con-
tinued slowly to advance for an hour along the broken and
rocky banks, and was amply repaid by the grandeur of the
scene. The gloomy depth of the ravine well accorded with
the universal signs of violence. On every side were lying
irregular masses of rock and torn-up trees; other trees,
though still erect, were decayed to the heart and ready to
fall. The entangled mass of the thriving and the fallen
reminded me of the forests within the tropics — yet there was
a difference: for in these still solitudes, Death, instead of
Life, seemed the predominant spirit. I followed the water-
course till I came to a spot where a great slip had cleared a
straight space down the mountain side. By this road I
ascended to a considerable elevation, and obtained a good
view of the surrounding woods. The trees all belong to
one kind, the Fagus betuloides ; for the number of the other
species of Fagus and of the Winter's Bark, is quite incon-
siderable. This beech keeps its leaves throughout the year;
but its foliage is of a peculiar brownish-green colour, with
a tinge of yellow. As the whole landscape is thus coloured,
it has a sombre, dull appearance; nor is it often enlivened
by the rays of the sun.

December zoth. — One side of the harbour is formed by a
hill about 1500 feet high, which Captain Fitz Roy has called
after Sir J. Banks, in commemoration of his disastrous
excursion, which proved fatal to two men of his party, and
nearly so to Dr. Solander. The snowstorm, which was the
cause of their misfortune, happened in the middle of Janu-
ary, corresponding to our July, and in the latitude of Dur-
ham ! I was anxious to reach the summit of this mountain
VOL. xxix — H HC

226 CHARLES DARWIN

to collect alpine plants ; for flowers of any kind in the lower
parts are few in number. We followed the same water-
course as on the previous day, till it dwindled away, and we
were then compelled to crawl blindly among the trees.
These, from the effects of the elevation and of the impetuous
winds, were low, thick and crooked. At length we reached
that which from a distance appeared like a carpet of fine
green turf, but which, to our vexation, turned out to be a
compact mass of little beech-trees about four or five feet
high. They were as thick together as box in the border of
a garden, and we were obliged to struggle over the flat but
treacherous surface. After a little more trouble we gained
the peat, and then the bare slate rock.

A ridge connected this hill with another, distant some
miles, and more lofty, so that patches of snow were lying
on it. As the day was not far advanced, I determined to
walk there and collect plants along the road. It would have
been very hard work, had it not been for a well-beaten and
straight path made by the guanacos; for these animals, like
sheep, always follow the same line. When we reached the
hill we found it the highest in the immediate neighbourhood,
and the waters flowed to the sea in opposite directions. We
obtained a wide view over the surrounding country: to the
north a swampy moorland extended, but to the south we
had a scene of savage magnificence, well becoming Tierra
del Fuego. There was a degree of mysterious grandeur
in mountain behind mountain, with the deep intervening
valleys, all covered by one thick, dusky mass of forest. The
atmosphere, likewise, in this climate, where gale succeeds
gale, with rain, hail, and sleet, seems blacker than anywhere
else. In the Strait of Magellan looking due southward from
Port Famine, the distant channels between the mountains
appeared from their gloominess to lead beyond the confines
of this world.

December 2ist. — The Beagle got under way: and on the
succeeding day, favoured to an uncommon degree by a fine
easterly breeze, we closed in with the Barnevelts, and run-
ning past Cape Deceit with its stony peaks, about three
o'clock doubled the weather-beaten Cape Horn. The evening
was calm and bright, and we enjoyed a fine view of the sur-

THE VOYAGE OF THE BEAGLE 227

rounding isles. Cape Horn, however, demanded his tribute,
and before night sent us a gale of wind directly in our teeth.
We stood out to sea, and on the second day again made the
land, when we saw on our weather-bow this notorious prom-
ontory in its proper form — veiled in a mist, and its dim
outline surrounded by a storm of wind and water. Great
black clouds were rolling across the heavens, and squalls
of rain, with hail, swept by us with such extreme violence,
that the Captain determined to run into Wigwam Cove.
This is a snug little harbour, not far from Cape Horn ; and
here, at Christmas-eve, we anchored in smooth water. The
only thing which reminded us of the gale outside, was every
now and then a puff from the mountains, which made the
ship surge at her anchors.

December 25th. — Close by the Cove, a pointed hill, called
Kater's Peak, rises to the height of 1700 feet. The sur-
rounding islands all consist of conical masses of greenstone,
associated sometimes with less regular hills of baked and
altered clay-slate. This part of Tierra del Fuego may be
considered as the extremity of the submerged chain of
mountains already alluded to. The cove takes its name of
" Wigwam " from some of the Fuegian habitations ; but every
bay in the neighbourhood might be so called with equal
propriety. The inhabitants, living chiefly upon shell-fish, are
obliged constantly to change their place of residence ; but
they return at intervals to the same spots, as is evident from
the piles of old shells, which must often amount to many
tons in weight. These heaps can be distinguished at a long
distance by the bright green colour of certain plants, which
invariably grow on them. Among these may be enumerated
the wild celery and scurvy grass, two very serviceable plants,
the use of which has not been discovered by the natives.

The Fuegian wigwam resembles, in size and dimensions,
a haycock. It merely consists of a few broken branches
stuck in the ground, and very imperfectly thatched on one
side with a few tufts of grass and rushes. The whole cannot
be the work of an hour, and it is only used for a few days.
At Goeree Roads I saw a place where one of these naked
men had slept, which absolutely offered no more cover than
the form of a hare. The man was evidently living by him-

228 CHARLES DARWIN

self, and York Minster said he was "very bad man," and
that probably he had stolen something. On the west coast,
however, the wigwams are rather better, for they are covered
with seal-skins. We were detained here several days by the
bad weather. The climate is certainly wretched: the sum-
mer solstice was now passed, yet every day snow fell on the
hills, and in the valleys there was rain, accompanied by
sleet. The thermometer generally stood about 45°, but in
the night fell to 38° or 40°. From the damp and boisterous
state of the atmosphere, not cheered by a gleam of sun-
shine, one fancied the climate even worse than it really was.
While going one day on shore near Wollaston Island, we
pulled alongside a canoe with six Fuegians. These were the
most abject and miserable creatures I anywhere beheld. On
the east coast the natives, as we have seen, have guanaco
cloaks, and on the west they possess seal-skins. Amongst
these central tribes the men generally have an otter-skin, or
some small scrap about as large as a pocket-handkerchief,
which is barely sufficient to cover their backs as low down
as their loins. It is laced across the breast by strings, and
according as the wind blows, it is shifted from side to side.
But these Fuegians in the canoe were quite naked, and even
one full-grown woman was absolutely so. It was raining
heavily, and the fresh water, together with the spray, trickled
down her body. In another harbour not far distant, a
woman, who was suckling a recently-born child, came one
day alongside the vessel, and remained there out of mere
curiosity, whilst the sleet fell and thawed on her naked
bosom, and on the skin of her naked baby ! These poor
wretches were stunted in their growth, their hideous faces
bedaubed with white paint, their skins filthy and greasy,
their hair entangled, their voices discordant, and their ges-
tures violent. Viewing such men, one can hardly make one's
self believe that they are fellow-creatures, and inhabitants
of the same world. It is a common subject of conjecture
what pleasure in life some of the lower animals can enjoy:
how much more reasonably the same question may be asked
with respect to these barbarians ! At night, five or six
human beings, naked and scarcely protected from the wind
and rain of this tempestuous climate, sleep on the wet

THE VOYAGE OF THE BEAGLE 229

ground coiled up like animals. Whenever it is low water,
winter or summer, night or day, they must rise to pick shell-
fish from the rocks; and the women either dive to collect
sea-eggs, or sit patiently in their canoes, and with a baited
hair-line without any hook, jerk out little fish. If a seal is
killed, or the floating carcass of a putrid whale is discovered,
it is a feast; and such miserable food is assisted by a few
tasteless berries and fungi.

They often suffer from famine: I heard Mr. Low, a seal*
ing-master intimately acquainted with the natives of this
country, give a curious account of the state of a party of
one hundred and fifty natives on the west coast, who were
very thin and in great distress. A succession of gales pre-
vented the women from getting shell-fish on the rocks, and
they could not go out in their canoes to catch seal. A small
party of these men one morning set out, and the other
Indians explained to him, that they were going a four days'
journey for food: on their return, Low went to meet them,
and he found them excessively tired, each man carrying
a great square piece of putrid whale's-blubber with a hole
in the middle, through which they put their heads, like the
Gauchos do through their ponchos or cloaks. As soon as
the blubber was brought into a wigwam, an old man cut off
thin slices, and muttering over them, broiled them for a
minute, and distributed them to the famished party, who
during this time preserved a profound silence. Mr. Low
believes that whenever a whale is cast on shore, the natives
bury large pieces of it in the sand, as a resource in time of
famine; and a native boy, whom he had on board, once
found a stock thus buried. The different tribes when at
war are cannibals. From the concurrent, but quite inde-
pendent evidence of the boy taken by Mr. Low, and of
Jemmy Button, it is certainly true, that when pressed in
•winter by hunger, they kill and devour their old women
before they kill their dogs: the boy, being asked by Mr.
Low why they did this, answered, " Doggies catch otters,
old women no." This boy described the manner in which
they are killed by being held over smoke and thus choked;
he imitated their screams as a joke, and described the parts
of their bodies which are considered best to eat. Horrid

230 CHARLES DARWIN

as such a death by the hands of their friends and relatives
must be, the fears of the old women, when hunger begins
to press, are more painful to think of; we are told that they
then often run away into the mountains, but that they are
pursued by the men and brought back to the slaughter-house
at their own firesides !

Captain Fitz Roy could never ascertain that the Fuegians
have any distinct belief in a future life. They sometimes
bury their dead in caves, and sometimes in the mountain
forests; we do not know what ceremonies they perform.
Jemmy Button would not eat land-birds, because " eat dead
men " : they are unwilling even to mention their dead friends,
We have no reason to believe that they perform any sort of
religious worship; though perhaps the muttering of the old
man before he distributed the putrid blubber to his famished
party, may be of this nature. Each family or tribe has a
wizard or conjuring doctor, whose office we could never
clearly ascertain. Jemmy believed in dreams, though not, as
I have said, in the devil: I do not think that our Fuegians
were much more superstitious than some of the sailors ; for
an old quartermaster firmly believed that the successive
heavy gales, which we encountered off Cape Horn, were
caused by our having the Fuegians on board. The nearest
approach to a religious feeling which I heard of, was shown
by York Minster, who, when Mr. Bynoe shot some very
young ducklings as specimens, declared in the most solemn
manner, " Oh, Mr. Bynoe, much rain, snow, blow much."
This was evidently a retributive punishment for wasting
human food. In a wild and excited manner he also related,
that his brother, one day whilst returning to pick up some
dead birds which he had left on the coast, observed some
feathers blown by the wind. His brother said (York imi-
tating his manner), "What that?" and crawling onwards,
he peeped over the cliff, and saw " wild man " picking his
birds; he crawled a little nearer, and then hurled down a
great stone and killed him. York declared for a long time
afterwards storms raged, and much rain and snow fell.
As far as we could make out, he seemed to consider the
elements themselves as the avenging agents : it is evident in
this case, how naturally, in a race a little more advanced

THE VOYAGE OF THE BEAGLE 231

in culture, the elements would become personified. What
the " bad wild men " were, has always appeared to me most
mysterious: from what York said, when we found the place
like the form of a hare, where a single man had slept the
night before, I should have thought that they were thieves
who had been driven from their tribes; but other obscure
speeches made me doubt this; I have sometimes imagined
that the most probable explanation was that they were
insane.

The different tribes have no government or chief; yet
each is surrounded by other hostile tribes, speaking different
dialects, and separated from each other only by a deserted
border or neutral territory: the cause of their warfare ap-
pears to be the means of subsistence. Their country is a
broken mass of wild rocks, lofty hills, and useless forests:
and these are viewed through mists and endless storms. The
habitable land is reduced to the stones on the beach ; in
search of food they are compelled unceasingly to wander
from spot to spot, and so steep is the coast, that they can
only move about in their wretched canoes. They cannot
know the feeling of having a home, and still less that of do-
mestic affection; for the husband is to the wife a brutal
master to a laborious slave. Was a more horrid deed ever
perpetrated, than that witnessed on the west coast by Byron,
who saw a wretched mother pick up her bleeding dying
infant-boy, whom her husband had mercilessly dashed on the
stones for dropping a basket of sea-eggs ! How little can
the higher powers of the mind be brought into play: what is
there for imagination to picture, for reason to compare, for
judgment to decide upon? to knock a limpet from the rock
does not require even cunning, that lowest power of the
mind. Their skill in some respects may be compared to the
instinct of animals; for it is not improved by experience:
the canoe, their most ingenious work, poor as it is, has re-
mained the same, as we know from Drake, for the last two
hundred and fifty years.

Whilst beholding these savages, one asks, whence have
they come ? What could have tempted, or what change com-
pelled a tribe of men, to leave the fine regions of the north,
to travel down the Cordillera or backbone of America, to

232 CHARLES DARWIN

invent and build canoes, which are not used by the tribes
of Chile, Peru, and Brazil, and then to enter on one of the
most inhospitable countries within the limits of the globe?
Although such reflections must at first seize on the mind, yet
we may feel sure that they are partly erroneous. There is
no reason to believe that the Fuegians decrease in number;
therefore we must suppose that they enjoy a sufficient share
of happiness, of whatever kind it may be, to render life
worth having. Nature by making habit omnipotent, and its
effects hereditary, has fitted the Fuegian to the climate and
the productions of his miserable country.

After having been detained six days in Wigwam Cove by
very bad weather, we put to sea on the 3Oth of December.
Captain Fitz Roy wished to get westward to land York and
Fuegia in their own country. When at sea we had a constant
succession of gales, and the current was against us: we
drifted to 57° 23' south. On the nth of January, 1833, by
carrying a press of sail, we fetched within a few miles of
the great rugged mountain of York Minster (so called by
Captain Cook, and the origin of the name of the elder Fu-
egian), when a violent squall compelled us to shorten sail
and stand out to sea. The surf was breaking fearfully on
the coast, and the spray was carried over a cliff estimated
to 200 feet in height. On the I2th the gale was very heavy,
and we did not know exactly where we were : it was a most
unpleasant sound to hear constantly repeated, " keep a good
look-out to leeward." On the i3th the storm raged with its
full fury: our horizon was narrowly limited by the sheets
of spray borne by the wind. The sea looked ominous, like
a dreary waving plain with patches of drifted snow: whilst
the ship laboured heavily, the albatross glided with its ex-
panded wings right up the wind. At noon a great sea broke
over us, and filled one of the whale boats, which was
obliged to be instantly cut away. The poor Beagle trembled
at the shock, and for a few minutes would not obey her helm ;
but soon, like a good ship that she was, she righted and came
up to the wind again. Had another sea followed the first,
our fate would have been decided soon, and for ever. We
had now been twenty-four days trying in vain to get west-

THE VOYAGE OF THE BEAGLE 233

ward ; the men were worn out with fatigue, and they had not
had for many nights or days a dry thing to put on. Captain
Fitz Roy gave up the attempt to get westward by the outside
coast. In the evening we ran in behind False Cape Horn,
and dropped our anchor in forty-seven fathoms, fire flashing
from the windlass as the chain rushed round it. How de-
lightful was that still night, after having been so long in-
volved in the din of the warring elements !

January i^th, 1833. — The Beagle anchored in Goeree
Roads. Captain Fitz Roy having resolved to settle the Fu-
egians, according to their wishes, in Ponsonby Sound, four
boats were equipped to carry them there through the Beagle
Channel. This channel, which was discovered by Captain
Fitz Roy during the last voyage, is a most remarkable feature
in the geography of this, or indeed of any other country: it
may be compared to the valley of Lochness in Scotland, with
its chain of lakes and friths. It is about one hundred and
twenty miles long, with an average breadth, not subject to
any very great variation, of about two miles ; and is through-
out the greater part so perfectly straight, that the view,
bounded on each side by a line of mountains, gradually be-
comes indistinct in the long distance. It crosses the south-
ern part of Tierra del Fuego in an east and west line, and
in the middle is joined at right angles on the south side by
an irregular channel, which has been called Ponsonby Sound.
This is the residence of Jemmy Button's tribe and family.

igih. — Three whale-boats and the yawl, with a party of
twenty-eight, started under the command of Captain Fitz
Roy. In the afternoon we entered the eastern mouth of the
channel, and shortly afterwards found a snug little cove
concealed by some surrounding islets. Here we pitched our
tents and lighted our fires. Nothing could look more com-
fortable than this scene. The glassy water of the little har-
bour, with the branches of the trees hanging over the rocky
beach, the boats at anchor, the tents supported by the crossed
oars, and the smoke curling up the wooded valley, formed a
picture of quiet retirement. The next day (20th) we smooth-
ly glided onwards in our little fleet, and came to a more in-
habited district. Few if any of these natives could ever
have seen a white man ; certainly nothing could exceed their

234 CHARLES DARWIN

astonishment at the apparition of the four boats. Fires were
lighted on every point (hence the name of Tierra del Fuego,
or the land of fire), both to attract our attention and to
spread far and wide the news. Some of the men ran for
miles along the shore. I shall never forget how wild and
savage one group appeared : suddenly four or five men came
to the edge of an overhanging cliff; they were absolutely
naked, and their long hair streamed about their faces; they
held rugged staffs in their hands, and, springing from the
ground, they waved their arms round their heads, and sent
forth the most hideous yells.

At dinner-time we landed among a party of Fuegians.
At first they were not inclined to be friendly; for until the
Captain pulled in ahead of the other boats, they kept their
slings in their hands. We soon, however, delighted them by
trifling presents, such as tying red tape round their heads.
They liked our biscuit: but one of the savages touched with
his finger some of the meat preserved in tin cases which I
was eating, and feeling it soft and cold, showed as much dis-
gust at it, as I should have done at putrid blubber. Jemmy
was thoroughly ashamed of his countrymen, and declared his
own tribe were quite different, in which he was wofully mis-
taken. It was as easy to please as it was difficult to satisfy
these savages. Young and old, men and children, never
ceased repeating the word " yammerschooner," which means
"give me." After pointing to almost every object, one after
the other, even to the buttons on our coats, and saying their
favourite word in as many intonations as possible, they would
then use it in a neuter sense, and vacantly repeat "yammer-
schooner." After yammerschoonering for any article very
eagerly, they would by a simple artifice point to their young
women or little children, as much as to say, "If you will
not give it me, surely you will to such as these."

At night we endeavoured in vain to find an uninhabited
cove; and at last were obliged to bivouac not far from a
party of natives. They were very inoffensive as long as they
were few in numbers, but in the morning (2ist) being joined
by others they showed symptoms of hostility, and we thought
that we should have come to a skirmish. An European
labours under great disadvantages when treating with sav-

THE VOYAGE OF THE- BEAGLE 235

ages like these, who have not the least idea of the power of
fire-arms. In the very act of levelling his musket he appears
to the savage far inferior to a man armed with a bow and
arrow, a spear, or even a sling. Nor is it easy to teach them
our superiority except by striking a fatal blow. Like wild
beasts, they do not appear to compare numbers ; for each in-
dividual, if attacked, instead of retiring, will endeavour to
dash your brains out with a stone, as certainly as a tiger
under similar circumstances would tear you. Captain Fitz
Roy on one occasion being very anxious, from good reasons,
to frighten away a small party, first flourished a cutlass near
them, at which they only laughed; he then twice fired his
pistol close to a native. The man both times looked as-
tounded, and carefully but quickly rubbed his head; he then
stared awhile, and gabbled to his companions, but he never
seemed to think of running away. We can hardly put our-
selves in the position of these savages, and understand their
actions. In the case of this Fuegian, the possibility of such
a sound as the report of a gun close to his ear could never
have entered his mind. He perhaps literally did not for a
second know whether it was a sound or a blow, and there-
fore very naturally rubbed his head. In a similar manner,
when a savage sees a mark struck by a bullet, it may be some
time before he is able at all to understand how it is effected ;
for the fact of a body being invisible from its velocity would
perhaps be to him an idea totally inconceivable. Moreover,
the extreme force of a bullet, that penetrates a hard sub-
stance without tearing it, may convince the savage that it
has no force at all. Certainly I believe that many savages
of the lowest grade, such as these of Tierra del Fuego, have
seen objects struck, and even small animals killed by the
musket, without being in the least aware how deadly an in-
strument it is.

22nd. — After having passed an unmolested night, in what
would appear to be neutral territory between Jemmy's tribe
and the people whom we saw yesterday, we sailed pleasantly
along. I do not know anything which shows more clearly
the hostile state of the different tribes, than these wide border
or neutral tracts. Although Jemmy Button well knew the
iproe of our party, he was, at first, unwilling to land amidsf

236 CHARLES DARWIN

the hostile tribe nearest to his own. He often told us how
the savage Oens men " when the leaf red," crossed the moun-
tains from the eastern coast of Tierra del Fuego, and made
inroads on the natives of this part of the country. It was
most curious to watch him when thus talking, and see his
eyes gleaming and his whole face assume a new and wild
expression. As we proceeded along the Beagle Channel, the
scenery assumed a peculiar and very magnificent character;
but the effect was much lessened from the lowness of the
point of view in a boat, and from looking along the valley,
and thus losing all the beauty of a succession of ridges. The
mountains were here about three thousand feet high, and
terminated in sharp and jagged points. They rose in one
unbroken sweep from the water's edge, and were covered to
the height of fourteen or fifteen hundred feet by the dusky-
coloured forest. It was most curious to observe, as far as
the eye could range, how level and truly horizontal the line
on the mountain side was, at which trees ceased to grow : it
precisely resembled the high-water mark of drift-weed on a
sea-beach.

At night we slept close to the junction of Ponsonby Sound
with the Beagle Channel. A small family of Fuegians, who
were living in the cove, were quiet and inoffensive, and soon
joined our party round a blazing fire. We were well clothed,
and though sitting close to the fire were far from too warm ;
yet these naked savages, though further off, were observed,
to our great surprise, to be streaming with perspiration at
undergoing such a roasting. They seemed, however, very
well pleased, and all joined in the chorus of the seamen's
songs : but the manner in which they were invariably a little
behindhand was quite ludicrous.

During the night the news had spread, and early in the
morning (23rd) a fresh party arrived, belonging to the Teke-
nika, or Jemmy's tribe. Several of them had run so fast that
their noses were bleeding, and their mouths frothed from
the rapidity with which they talked; and with their naked
bodies all bedaubed with black, white,1 and red, they looked

1 This substance, when dry, is tolerably compact, and of little specific

gravity: Professor Ehrenberg has examined it: he states (Konig Akad.
er Wissen: Berlin, Feb. 1845) that it is composed of infusoria, including
fourteen polygastrica, and four phytolitharia. He says that they are all

THE VOYAGE OF THE BEAGLE 237

like so many demoniacs who had been fighting. We then
proceeded (accompanied by twelve canoes, each holding four
or five people) down Ponsonby Sound to the spot where poor
Jemmy expected to find his mother and relatives. He had
already heard that his father was dead; but as he had had
a "dream in his head" to that effect, he did not seem to
care much about it, and repeatedly comforted himself with
the very natural reflection — " Me no help it." He was not
able to learn any particulars regarding his father's death, as
his relations would not speak about it.

Jemmy was now in a district well known to him, and
guided the boats to a quiet pretty cove named Woollya, sur-
rounded by islets, every one of which and every point had
its proper native name. We found here a family of Jemmy's
tribe, but not his relations: we made friends with them;
and in the evening they sent a canoe to inform Jemmy's
mother and brothers. The cove was bordered by some acres
of good sloping land, not covered (as elsewhere) either by
peat or by forest-trees. Captain Fitz Roy originally in-
tended, as before stated, to have taken York Minster and
Fuegia to their own tribe on the west coast; but as they ex-
pressed a wish to remain here, and as the spot was singularly
favourable, Captain Fitz Roy determined to settle here the
whole party, including Matthews, the missionary. Five days
were spent in building for them three large wigwams, in
landing their goods, in digging two gardens, and sowing
seeds.

The next morning after our arrival (the 24th) the Fu-
egians began to pour in, and Jemmy's mother and brothers
arrived. Jemmy recognised the stentorian voice of one of
his brothers at a prodigious distance. The meeting was less
interesting than that between a horse, turned out into a field,
when he joins an old companion. There was no demonstra-
tion of affection; they simply stared for a short time at
each other; and the mother immediately went to look after

inhabitants of fresh-water: this is a beautiful example of the results obtain-
able through Professor Ehrenberg's microscopic researches; for Jemmy
Button told me that it is always collected at the bottoms of mountain-
brooks. It is, moreover, a striking fact in the geographical distribution
of the hifusoria, which are well known to have very wide ranges, that all
the species in this substance, although brought from the extreme southern
point of Tierra del Fuego, are old, known forms.

238 CHARLES DARWIN

her canoe. We heard, however, through York that the
mother has been inconsolable for the loss of Jemmy, and had
searched everywhere for him, thinking that he might have
been left after having been taken in the boat. The women
took much notice of and were very kind to Fuegia. We had
already perceived that Jemmy had almost forgotten his own
language. I should think there was scarcely another human
being with so small a stock of language, for his English was
very imperfect. It was laughable, but almost pitiable, to
hear him speak to his wild brother in English, and then ask
him in Spanish ("no sabe?") whether he did not under-
stand him.

Everything went on peaceably during the three next days,
whilst the gardens were digging and wigwams building. We
estimated the number of natives at about one hundred and
twenty. The women worked hard, whilst the men lounged
about all day long, watching us. They asked for everything
they saw, and stole what they could. They were delighted
at our dancing and singing, and were particularly interested
at seeing us wash in a neighbouring brook ; they did not pay
much attention to anything else, not even to our boats. Of
all the things which York saw, during his absence from his
country, nothing seems more to have astonished him than
an ostrich, near Maldonado : breathless with astonishment,
he came running to Mr. Bynoe, with whom he was out walk-
ing— " Oh, Mr. Bynoe, oh, bird all same horse ! " Much as
our white skins surprised the natives, by Mr. Low's account
a negro-cook to a sealing vessel, did so more effectually ; and
the poor fellow was so mobbed and shouted at that he would
never go on shore again. Everything went on so quietly,
that some of the officers and myself took long walks in the
surrounding hills and woods. Suddenly, however, on the
27th, every woman and child disappeared. We were all un-
easy at this, as neither York nor Jemmy could make out
the cause. It was thought by some that they had been fright-
ened by our cleaning and firing off our muskets on the pre-
vious evening ; by others, that it was owing to offence taken
by an old savage, who, when told to keep further off, had
coolly spit in the sentry's face, and had then, by gestures
acted over a sleeping Fuegian, plainly showed, as it was said,

THE VOYAGE OF THE- BEAGLE 239

that he should like to cut up and eat our man. Captain
Fitz Roy, to avoid the chance of an encounter, which would
have been fatal to so many of the Fuegians, thought it ad-
visable for us to sleep at a cove a few miles distant. Mat-
thews, with his usual quiet fortitude (remarkable in a man
apparently possessing little energy of character), determined
to stay with the Fuegians, who evinced no alarm for them-
selves ; and so we left them to pass their first awful night.

On our return in the morning (28th) we were delighted
to find all quiet, and the men employed in their canoes
spearing fish. Captain Fitz Roy determined to send the
yawl and one whale-boat back to the ship ; and to proceed
with the two other boats, one under his own command (in
which he most kindly allowed me to accompany him), and
one under Mr. Hammond, to survey the western parts of
the Beagle Channel, and afterwards to return and visit the
settlement. The day to our astonishment was overpower-
ingly hot, so that our skins were scorched: with this beau-
tiful weather, the view in the middle of the Beagle Channel
was very remarkable. Looking towards either hand, no ob-
ject intercepted the vanishing points of this long canal be-
tween the mountains. The circumstance of its being an arm
of the sea was rendered very evident by several huge whales'
spouting in different directions. On one occasion I saw two
of these monsters, probably male and female, slowly swim-
ming one after the other, within less than a stone's throw
of the shore, over which the beech-tree extended its branches.

We sailed on till it was dark, and then pitched our tents
in a quiet creek. The greatest luxury was to find for our
beds a beach of pebbles, for they were dry and yielded to
the body. Peaty soil is damp; rock is uneven and hard;
sand gets into one's meat, when cooked and eaten boat-fash-
ion; but when lying in our blanket-bags, on a good bed of
smooth pebbles, we passed most comfortable nights.

It was my watch till one o'clock. There is something
very solemn in these scenes. At no time does the conscious-
ness in what a remote corner of the world you are then

* One day, off the East coast of Tierra del Fuego, we saw a grand sight
in several spermaceti whales jumping upright quite out of the water, with
the exception of their tail-fins. As they fell down sideways, they splashed
the water high up, and the sound reverberated like a distant broadside.

standing, come so strongly before the mind. Everything
tends to this effect; the stillness of the night is interrupted
only by the heavy breathing of the seamen beneath the tents,
and sometimes by the cry of a night-bird. The occasional
barking of a dog, heard in the distance, reminds one that it
is the land of the savage.

January zpth. — Early in the morning we arrived at the
point where the Beagle Channel divides into two arms; and
we entered the northern one. The scenery here becomes
even grander than before. The lofty mountains on the north
side compose the granitic axis, or backbone of the country,
and boldly rise to a height of between three and four thou-
sand feet, with one peak above six thousand feet. They are
covered by a wide mantle of perpetual snow, and numerous
cascades pour their waters, through the woods, into the nar-
row channel below. In many parts, magnificent glaciers ex-
tend from the mountain side to the water's edge. It is
scarcely possible to imagine anything more beautiful than
the beryl-like blue of these glaciers, and especially as con-
trasted with the dead white of the upper expanse of snow.
The fragments which had fallen from the glacier into the
water were floating away, and the channel with its icebergs
presented, for the space of a mile, a miniature likeness of
the Polar Sea. The boats being hauled on shore at our
dinner-hour, we were admiring from the distance of half a
mile a perpendicular cliff of ice, and were wishing that some
more fragments would fall. At last, down came a mass with
a roaring noise, and immediately we saw the smooth outline
of a wave travelling towards us. The men ran down as
quickly as they could to the boats; for the chance of their
being dashed to pieces was evident. One of the seamen just
caught hold of the bows, as the curling breaker reached it:
he was knocked over and over, but not hurt; and the boats,
though thrice lifted on high and let fall again, received no
damage. This was most fortunate for us, for we were a
hundred miles distant from the ship, and we should have
been left without provisions or fire-arms. I had previously
observed that some large fragments of rock on the beach had
been lately displaced; but until seeing this wave, I did not
understand the cause. One side of the creek was formed

THE VOYAGE OF THE BEAGLE 241

by a spur of mica-slate; the head by a cliff of ice about
forty feet high; and the other side by a promontory fifty
feet high, built up of huge rounded fragments of granite
and mica-slate, out of which old trees were growing. This
promontory was evidently a moraine, heaped up at a period
when the glacier had greater dimensions.

When we reached the western mouth of this northern
branch of the Beagle Channel, we sailed amongst many un-
known desolate islands, and the weather was wretchedly bad.
We met with no natives. The coast was almost everywhere
so steep, that we had several times to pull many miles before
we could find space enough to pitch our two tents : one night
we slept on large round boulders, with putrefying sea-weed
between them ; and when the tide rose, we had to get up and
move our blanket-bags. The farthest point westward which
we reached was Stewart Island, a distance of about one hun-
dred and fifty miles from our ship. We returned into the
Beagle Channel by the southern arm, and thence proceeded,
with no adventure, back to Ponsonby Sound.

February 6th. — We arrived at Woollya. Matthews gave
so bad an account of the conduct of the Fuegians, that Cap-
tain Fitz Roy determined to take him back to the Beagle;
and ultimately he was left at New Zealand, where his brother
was a missionary. From the time of our leaving, a regular
system of plunder commenced; fresh parties of the natives
kept arriving: York and Jemmy lost many things, and Mat-
thews almost everything which had not been concealed un-
derground. Every article seemed to have been torn up and
divided by the natives. Matthews described the watch he
was obliged always to keep as most harassing; night and
day he was surrounded by the natives, who tried to tire him
out by making an incessant noise close to his head. One day
an old man, whom Matthews asked to leave his wigwam,
immediately returned with a large stone in his hand : another
day a whole party came armed with stones and stakes, and
some of the younger men and Jemmy's brother were crying :
Matthews met them with presents. Another party showed
by signs that they wished to strip him naked and pluck all
the hairs out of his face and body. I think we arrived just
in time to save his life. Jemmy's relatives had been so vain

242 CHARLES DARWIN

and foolish, that they had showed to strangers their plun-
der, and their manner of obtaining it. It was quite melan-
choly leaving the three Fuegians with their savage country-
men; but it was a great comfort that they had no personal
fears. York, being a powerful resolute man, was pretty sure
to get on well, together with his wife Fuegia. Poor Jemmy
looked rather disconsolate, and would then, I have little
doubt, have been glad to have returned with us. His own
brother had stolen many things from him; and as he re-
marked, "What fashion call that:" he abused his country-
men, " all bad men, no sabe (know) nothing." and, though
I never heard him swear before, " damned fools." Our three
Fuegians, though they had been only three years with civil-
ized men, would, I am sure, have been glad to have retained
their new habits; but this was obviously impossible. I fear
it is more than doubtful, whether their visit will have been
of any use to them.

In the evening, with Matthews on board, we made sail
back to the ship, not by the Beagle Channel, but by the
southern coast. The boats were heavily laden and the sea
rough, and we had a dangerous passage. By the evening
of the 7th we were on board the Beagle after an absence of
twenty days, during which time we had gone three hundred
miles in the open boats. On the nth, Captain Fitz Roy
paid a visit by himself to the Fuegians and found them going
on well ; and that they had lost very few more things.

On the last day of February in the succeeding year (1834),
the Beagle anchored in a beautiful little cove at the eastern
entrance of the Beagle Channel. Captain Fitz Roy deter-
mined on the bold, and as it proved successful, attempt to
beat against the westerly winds by the same route, which
we had followed in the boats to the settlement at Woollya.
We did not see many natives until we were near Ponsonby
Sound, where we were followed by ten or twelve canoes. The
natives did not at all understand the reason of our tacking,
and, instead of meeting us at each tack, vainly strove to
follow us in our zigzag course. I was amused at finding
what a difference the circumstance of being quite superior
in force made, in the interest of beholding these savages.

THE VOYAGE OF THE BEAGLE 243

While in the boats I got to hate the very sound of their
voices, so much trouble did they give us. The first and last
word was " yammerschooner." When, entering some quiet
little cove, we have looked round and thought to pass a quiet
night, the odious word "yammerschooner" has shrilly sounded
from some gloomy nook, and then the little signal-smoke
has curled up to spread the news far and wide. On leaving
some place we have said to each other, " Thank Heaven, we
have at last fairly left these wretches ! " when one more faint
hallo from an all-powerful voice, heard at a prodigious dis-
tance, would reach our ears, and clearly could we distinguish
— " yammerschooner." But now, the more Fuegians the mer-
rier ; and very merry work it was. Both parties laughing,
wondering, gaping at each other; we pitying them, for giv-
ing us good fish and crabs for rags, etc. ; they grasping at the
chance of finding people so foolish as to exchange such splen-
did ornaments for a good supper. It was most amusing to
see the undisguised smile of satisfaction with which one
young woman with her face painted black, tied several bits
of scarlet cloth round her head with rushes. Her husband,
who enjoyed the very universal privilege in this country of
possessing two wives, evidently became jealous of all the at-
tention paid to his young wife; and, after a consultation
with his naked beauties, was paddled away by them.

Some of the Fuegians plainly showed that they had a fair
notion of barter. I gave one man a large nail (a most valu-
able present) without making any signs for a return; but he
immediately picked out two fish, and handed them up on the
point of his spear. If any present was designed for one
canoe, and it fell near another, it was invariably given to the
right owner. The Fuegian boy, whom Mr. Low had on
board, showed, by going into the most violent passion, that
he quite understood the reproach of being called a liar, which
in truth he was. We were this time, as on all former occa-
sions, much surprised at the little notice, or rather none
whatever, which was taken of many things, the use of which
must have been evident to the natives. Simple circum-
stances— such as the beauty of scarlet cloth or blue beads,
the absence of women, our care in washing ourselves, — ex-
cited their admiration far more than any grand or compli-

244 CHARLES DARWIN

cated object, such as our ship. Bougainville has well re-
marked concerning these people, that they treat the " chefs-
d'oeuvre de 1'industrie humaine, comme ils traitent les loix
de la nature et ses phenomenes."

On the 5th of March, we anchored in a cove at Woollya,
but we saw not a soul there. We were alarmed at this, for
the natives in Ponsonby Sound showed by gestures, that there
had been fighting; and we afterwards heard that the dreaded
Oens men had made a descent. Soon a canoe, with a little
flag flying, was seen approaching, with one of the men in it
washing the paint off his face. This man was poor Jemmy,
— now a thin, haggard savage, with long disordered hair, and
naked, except a bit of blanket round his waist. We did not
recognize him till he was close to us, for he was ashamed
of himself, and turned his back to the ship. We had left him
plump, fat, clean, and well-dressed ; — I never saw so complete
and grievous a change. As soon, however, as he was clothed,
and the first flurry was over, things wore a good appear-
ance. He dined with Captain Fitz Roy, and ate his dinner
as tidily as formerly. He told us that he had " too much "
(meaning enough) to eat, that he was not cold, that his re-
lations were very good people, and that he did not wish to go
back to England: in the evening we found out the cause of
this great change in Jemmy's feelings, in the arrival of his
young and nice-looking wife. With his usual good feeling,
he brought two beautiful otter-skins for two of his best
friends, and some spear-heads and arrows made with his own
hands for the Captain. He said he had built a canoe for him-
self, and he boasted that he could talk a little of his own
language ! But it is a most singular fact, that he appears to
have taught all his tribe some English: an old man sponta-
neously announced " Jemmy Button's wife." Jemmy had lost
all his property. He told us that York Minster had built
a large canoe, and with his wife Fuegia,* had several months
since gone to his own country, and had taken farewell by an
act of consummate villainy; he persuaded Jemmy and his

8 Captain Sulivan, who, since his voyage in the Beagle, has been em-
ployed on the survey of the Falkland Islands, heard from a sealer in (1842?),
that when in the western part of the Strait of Magellan, he was_ astonished
ly a native woman coming on board, who could talk some English. With-
fcit doubt this was Fuegia Basket. She lived (I fear the term probably
dears a double interpretation) some days on board.

THE VOYAGE OF THE BEAGLE 245

mother to come with him, and then on the way deserted them
by night, stealing every article of their property.

Jemmy went to sleep on shore, and in the morning re-
turned, and remained on board till the ship got under way,
which frightened his wife, who continued crying violently
till he got into his canoe. He returned loaded with valuable
property. Every soul on board was heartily sorry to shake
hands with him for the last time. I do not now doubt that
he will be as happy as, perhaps happier than, if he had never
left his own country. Every one must sincerely hope that
Captain Fitz Roy's noble hope may be fulfilled, of being re-
warded for the many generous sacrifices which he made for
these Fuegians, by some shipwrecked sailor being protected
by the descendants of Jemmy Button and his tribe! When
Jemmy reached the shore, he lighted a signal fire, and the
smoke curled up, bidding us a last and long farewell, as the
ship stood on her course into the open sea.

The perfect equality among the individuals composing the
Fuegian tribes must for a long time retard their civilization.
As we see those animals, whose instinct compels them to live
in society and obey a chief, are most capable of improve-
ment, so is it with the races of mankind. Whether we look
at it as a cause or a consequence, the more civilized always
have the most artificial governments. For instance, the in-
habitants of Otaheite, who, when first discovered, were gov-
erned by hereditary kings, had arrived at a far higher grade
than another branch of the same people, the New Zealanders,
— who, although benefited by being compelled to turn their
attention to agriculture, were republicans in the most abso-
lute sense. In Tierra del Fuego, until some chief shall arise
with power sufficient to secure any acquired advantage, such
as the domesticated animals, it seems scarcely possible that
the political state of the country can be improved. At pres-
ent, even a piece of cloth given to one is torn into shreds
and distributed; and no one individual becomes richer than
another. On the other hand, it is difficult to understand how
a chief can arise till there is property of some sort by which
he might manifest his superiority and increase his pow.er.

I believe, in this extreme part of South America, man

246 CHARLES DARWIN

exists in a lower state of improvement than in any other part
of the world. The South Sea Islanders, of the two races
inhabiting the Pacific, are comparatively civilized. The
Esquimau in his subterranean hut, enjoys some of the com-
forts of life, and in his canoe, when fully equipped, mani-
fests much skill. Some of the tribes of Southern Africa,
prowling about in search of roots, and living concealed on
the wild and arid plains, are sufficiently wretched. The Aus-
tralian, in the simplicity of the arts of life, comes nearest the
Fuegian : he can, however, boast of his boomerang, his spear
and throwing-stick, his method of climbing trees, of tracking
animals, and of hunting. Although the Australian may be
superior in acquirements, it by no means follows that he is
likewise superior in mental capacity: indeed, from what I
saw of the Fuegians when on board, and from what I have
read of the Australians, I should think the case was exactly
the reverse.

IN THE end of May, 1834, we entered for a second time
the eastern mouth of the Strait of Magellan. The coun-
try on both sides of this part of the Strait consists of
nearly level plains, like those of Patagonia. Cape Negro, a
little within the second Narrows, may be considered as the
point where the land begins to assume the marked features
of Tierra del Fuego. On the east coast, south of the Strait,
broken park-like scenery in a like manner connects these two
countries, which are opposed to each other in almost every
feature. It is truly surprising to find in a space of twenty
miles such a change in the landscape. If we take a rather
greater distance, as between Port Famine and Gregory Bay,
that is about sixty miles, the difference is still more wonder-
ful. At the former place, we have rounded mountains con-
cealed by impervious forests, which are drenched with the
rain, brought by an endless succession of gales; while at
Cape Gregory, there is a clear and bright blue sky over the
dry and sterile plains. The atmospheric currents,1 although
rapid, turbulent, and unconfined by any apparent limits, yet
seem to follow, like a river in its bed, a regularly determined
course.

248 CHARLES DARWIN

During our previous visit (in January), we had an inter-
view at Cape Gregory with the famous so-called gigantic
Patagonians, who gave us a cordial reception. Their height
appears greater than it really is, from their large guanaco
mantles, their long flowing hair, and general figure: on an
average, their height is about six feet, with some men taller
and only a few shorter; and the women are also tall; alto-
gether they are certainly the tallest race which we anywhere
saw. In features they strikingly resemble the more northern
Indians whom I saw with Rosas, but they have a wilder and
more formidable appearance: their faces were much painted
with red and black, and one man was ringed and dotted with
white like a Fuegian. Captain Fitz Roy offered to take any
three of them on board, and all seemed determined to be of
the three. It was long before we could clear the boat; at
last we got on board with our three giants, who dined with
the Captain, and behaved quite like gentlemen, helping them-
selves with knives, forks, and spoons: nothing was so much
relished as sugar. This tribe has had so much communication
with sealers and whalers that most of the men can speak a
little English and Spanish; and they are half civilized, and
proportionally demoralized.

The next morning a large party went on shore, to barter
for skins and ostrich-feathers ; fire-arms being refused,
tobacco was in greatest request, far more so than axes or
tools. The whole population of the toldos, men, women, and
children, were arranged on a bank. It was an amusing
scene, and it was impossible not to like the so-called giants,
they were so thoroughly good-humoured and unsuspecting:
they asked us to come again. They seem to like to have
Europeans to live with them; and old Maria, an important
woman in the tribe, once begged Mr. Low to leave any one
of his sailors with them. They spend the greater part of the
year here; but in summer they hunt along the foot of the
Cordillera: sometimes they travel as far as the Rio Negro,
750 miles to the north. They are well stocked with horses,
each man having, according to Mr. Low, six or seven, and
all the women, and even children, their one own horse. In
the time of Sarmiento (1580), these Indians had bows and
arrows, now long since disused; they then also possessed

THE VOYAGE OF THE BEAGLE 249

some horses. This is a very curious fact, showing the extra-
ordinarily rapid multiplication of horses in South America.
The horse was first landed at Buenos Ay res in 1537, and the
colony being then for a time deserted, the horse ran wild ;* in
1580, only forty-three years afterwards, we hear of them at the
Strait of Magellan ! Mr. Low informs me, that a neighbour-
ing tribe of foot-Indians is now changing into horse-Indians :
the tribe at Gregory Bay giving them their worn-out horses,
and sending in winter a few of their best skilled men to hunt
for them.

June ist. — We anchored in the fine bay of Port Famine.
It was now the beginning of winter, and I never saw a more
cheerless prospect; the dusky woods, piebald with snow,
could be only seen indistinctly, through a drizzling hazy
atmosphere. We were, however, lucky in getting two fine
days. On one of these, Mount Sarmiento, a distant mountain
6800 feet high, presented a very noble spectacle. I was fre-
quently surprised in the scenery of Tierra del Fuego, at the
little apparent elevation of mountains really lofty. I suspect
it is owing to a cause which would not at first be imagined,
namely, that the whole mass, from the summit to the water's
edge, is generally in full view. I remember having seen a
mountain, first from the Beagle Channel, where the whole
sweep from the summit to the base was full in view, and then
from Ponsonby Sound across several successive ridges; and
it was curious to observe in the latter case, as each fresh
ridge afforded fresh means of judging of the distance, how
the mountain rose in height.

Before reaching Port Famine, two men were seen running
along the shore and hailing the ship. A boat was sent for
them. They turned out to be two sailors who had run away
from a sealing-vessel, and had joined the Patagonians. These
Indians had treated them with their usual disinterested hos-
pitality. They had parted company through accident, and
were then proceeding to Port Famine in hopes of finding
some ship, i dare say they were worthless vagabonds, but I
never saw more miserable-looking ones. They had been liv-
ing for some days on mussel-shells and berries, and their
tattered clothes had been burnt by sleeping so near their fires.

250 CHARLES DARWIN

They had been exposed night and day, without any shelter,
to the late incessant gales, with rain, sleet, and snow, and yet
they were in good health.

During our stay at Port Famine, the Fuegians twice came
and plagued us. As there were many instruments, clothes,
and men on shore, it was thought necessary to frighten them
away. The first time a few great guns were fired, when they
were far distant. It was most ludicrous to watch through a
glass the Indians, as often as the shot struck the water, take
up stones, and, as a bold defiance, throw them towards the
ship, though about a mile and a half distant ! A boat was
sent with orders to fire a few musket-shots wide of them.
The Fuegians hid themselves behind the trees, and for every
discharge of the muskets they fired their arrows; all, how-
ever, fell short of the boat, and the officer as he pointed at
them laughed. This made the Fuegians frantic with passion,
and they shook their mantles in vain rage. At last, seeing
the balls cut and strike the trees, they ran away, and we were
left in peace and quietness. During the former voyage the
Fuegians were here very troublesome, and to frighten them a
rocket was fired at night over their wigwams; it answered
effectually, and one of the officers told me that the clamour
first raised, and the barking of the dogs, was quite ludicrous
in contrast with the profound silence which in a minute or
two afterwards prevailed. The next morning not a single
Fuegian was in the neighbourhood.

When the Beagle was here in the month of February, I
started one morning at four o'clock to ascend Mount Tarn,
which is 2600 feet high, and is the most elevated point in this
immediate district. We went in a boat to the foot of the
mountain (but unluckily not to the best part), and then
began our ascent. The forest commences at the line of high-
water mark, and during the first two hours I gave over all
hopes of reaching the summit. So thick was the wood, that
it was necessary to have constant recourse to the compass;
for every landmark, though in a mountainous country, was
completely shut out. In the deep ravines, the death-like
scene of desolation exceeded all description; outside it was
blowing a gale, but in these hollows, not even a breath of
wind stirred the leaves of the tallest trees. So gloomy, cold,

THE VOYAGE OF THE BEAGLE 251

and wet was every part, that not even the fungi, mosses, or
ferns could flourish. In the valleys it was scarcely possible
to crawl along, they were so completely barricaded by great
mouldering trunks, which had fallen down in every direction.
When passing over these natural bridges, one's course was
often arrested by sinking knee deep into the rotten wood ; at
other times, when attempting to lean against a firm tree, one
was startled by finding a mass of decayed matter ready to
fall at the slightest touch. We at last found ourselves among
the stunted trees, and then soon reached the bare ridge, which
conducted us to the summit. Here was a view characteristic
of Tierra del Fuego; irregular chains of hills, mottled with
patches of snow, deep yellowish-green valleys, and arms of
the sea intersecting the land in many directions. The strong
wind was piercingly cold, and the atmosphere rather hazy, so
that we did not stay long on the top of the mountain. Our
descent was not quite so laborious as our ascent; for the
weight of the body forced a passage, and all the slips and
falls were in the right direction.

I have already mentioned the sombre and dull character of
the evergreen forests,8 in which two or three species of trees
grow, to the exclusion of all others. Above the forest land,
there are many dwarf alpine plants, which all spring from the
mass of peat, and help to compose it: these plants are very
remarkable from their close alliance with the species growing
on the mountains of Europe, though so many thousand miles
distant. The central part of Tierra del Fuego, where the
clay-slate formation occurs, is most favourable to the growth
of trees ; on the outer coast the poorer granitic soil, and a
situation more exposed to the violent winds, do not allow of
their attaining any great size. Near Port Famine I have seen
more large trees than anywhere else : I measured a Winter's
Bark which was four feet six inches in girth, and several of
the beech were as much as thirteen feet. Captain King also

•Captain Fitz Roy informs me that in April (our October), the leaves
Of those trees which grow near the base of the mountains, change colour,
but not those on the more elevated parts. I remember having read some
observations, showing that in England the leaves fall earlier in a warm
and fine autumn than in a late and cold one. The change in the colour
being here retarded in the more elevated, and therefore colder situations,
must be owing to the same general law of vegetation. The trees of Tierra
del Fuego during no part of the year entirely shed their leaves.

252 CHARLES DARWIN

mentions a beech which was seven feet in diameter, seven-
teen feet above the roots.

There is one vegetable production deserving notice from
its importance as an article of food to the Fuegians. It is a
globular, bright-yellow fungus, which grows in vast numbers
on the beech-trees. When young it is elastic and turgid, with
a smooth surface; but when mature
it shrinks, becomes tougher, and has
its entire surface deeply pitted or
honey-combed, as represented in the
accompanying wood-cut. This fun-
gus belongs to a new and curious
genus;* I found a second species on
another species of beech in Chile:
and Dr. Hooker informs me, that
just lately a third species has been
discovered on a third species of

beech in Van Dieman's Land. How singular is this relation-
ship between parasitical fungi and the trees on which they
grow, in distant parts of the world ! In Tierra del Fuego
the fungus in its tough and mature state is collected in large
quantities by the women and children, and is eaten un-
cooked. It has a mucilaginous, slightly sweet taste, with a
faint smell like that of a mushroom. With the exception
of a few berries, chiefly of a dwarf arbutus, the natives eat
no vegetable food besides this fungus. In New Zealand,
before the introduction of the potato, the roots of the fern
were largely consumed; at the present time, I believe, Tierra
del Fuego is the only country in the world where a cryp-
togamic plant affords a staple article of food.

The zoology of Tierra del Fuego, as might have been
expected from the nature of its climate and vegetation, is
very poor. Of mammalia, besides whales and seals, there is
one bat, a kind of mouse (Reithrodon chinchilloides), two
true mice, a ctenomys allied to or identical with the tucutuco,
two foxes (Canis Magellanicus and C. Azarae), a sea-otter,
the guanaco, and a deer. Most of these animals inhabit only

Bulgaria.

THE VOYAGE OF THE BEAGLE 253

the drier eastern parts of the country ; and the deer has never
been seen south of the Strait of Magellan. Observing the
general correspondence of the cliffs of soft sandstone, mud,
and shingle, on the opposite sides of the Strait, and on some
intervening islands, one is strongly tempted to believe that the
land was once joined, and thus allowed animals so delicate
and helpless as the tucutuco and Reithrodon to pass over.
The correspondence of the cliffs is far from proving any
junction; because such cliffs generally are formed by the
intersection of sloping deposits, which, before the elevation
of the land, had been accumulated near the then existing
shores. It is, however, a remarkable coincidence, that in the
two large islands cut off by the Beagle Channel from the
rest of Tierra del Fuego, one has cliffs composed of matter
that may be called stratified alluvium, which front similar
ones on the opposite side of the channel, — while the other is
exclusively bordered by old crystalline rocks : in the former,
called Navarin Island, both foxes and guanacos occur ; but in
the latter, Hoste Island, although similar in every respect,
and only separated by a channel a little more than half a mile
wide, I have the word of Jemmy Button for saying that
neither of these animals are found.

The gloomy woods are inhabited by few birds: occasion-
ally the plaintive note of a white-tufted tyrant-flycatcher
(Myiobius albiceps) may be heard, concealed near the sum-
mit of the most lofty trees ; and more rarely the loud strange
cry of a black wood-pecker, with a fine scarlet crest on its
head. A little, dusky-coloured wren (Scytalopus Magellani-
cus) hops in a skulking manner among the entangled mass
of the fallen and decaying trunks. But the creeper (Oxyurus
tupinieri) is the commonest bird in the country. Through-
out the beech forests, high up and low down, in the most
gloomy, wet, and impenetrable ravines, it may be met with.
This little bird no doubt appears more numerous than it
really is, from its habit of following with seeming curiosity
any person who enters these silent woods: continually utter-

industriously, after the manner of a willow-wren, hops about,
and searches for insects on every twig and branch. In the
more open parts, three or four species of finches, a thrush,
a starling (or Icterus), two Opetiorhynchi, and several hawks
and owls occur.

The absence of any species whatever in the whole class of
Reptiles, is a marked feature in the zoology of this country,
as well as in that of the Falkland Islands. I do not ground
this statement merely on my own observation, but I heard it
from the Spanish inhabitants of the latter place, and from
Jemmy Button with regard to Tierra del Fuego. On the
banks of the Santa Cruz, in 50° south, I saw a frog; and it
is not improbable that these animals, as well as lizards, may
be found as far south as the Strait of Magellan, where the
country retains the character of Patagonia; but within the
damp and cold limit of Tierra del Fuego not one occurs.
That the climate would not have suited some of the orders,
such as lizards, might have been foreseen ; but with respect
to frogs, this was not so obvious.

Beetles occur in very small numbers: it was long before I
could believe that a country as large as Scotland, covered
with vegetable productions and with a variety of stations,
could be so unproductive. The few which I found were
alpine species (Harpalidae and Heteromidae) living under
stones. The vegetable- feeding Chrysomelidae, so eminently
characteristic of the Tropics, are here almost entirely ab-
sent ;6 I saw very few flies, butterflies, or bees, and no crick-
ets or Orthoptera. In the pools of water I found but a few
aquatic beetles, and not any fresh-water shells: Succinea at
first appears an exception ; but here it must be called a terres-
trial shell, for it lives on the damp herbage far from the
water. Land-shells could be procured only in the same alpine
situations with the beetles. I have already contrasted the
climate as well as the general appearance of Tierra del

5 I believe I must except one alpine Haltica, and a single specimen of a
Melasoma. Mr. Waterhouse informs me, that of the Harpalicke there are
eight or nine species — the forms of the greater number being very peculiar:
of Heteromera, four or five species; of Rhyncophora, six or seven; and
of the following families one species in each: Staphylinidae, Elateridse,
Cebrionidse, Melolonthidse. The species in the other orders are even fewer.
In all the orders, the scarcity of the individuals is even more remark-
able than that of the species. Most of the Coleoptera have been carefully
described by Mr. Waterhouse in the Annals of Nat. Hist.

THE VOYAGE OF THE BEAGLE 255

Fuego with that of Patagonia ; and the difference is strongly
exemplified in the entomology. I do not believe they have
one species in common ; certainly the general character of the
insects is widely different.

If we turn from the land to the sea, we shall find the latter
as abundantly stocked with living creatures as the former is
poorly so. In all parts of the world a rocky and partially
protected shore perhaps supports, in a given space, a greater
number of individual animals than any other station. There
is one marine production which, from its importance, is
worthy of a particular history. It is the kelp, or Macrocystis
pyrifera. This plant grows on every rock from low-water
mark to a great depth, both on the outer coast and within the
channels.8 I believe, during the voyages of the Adventure
and Beagle, not one rock near the surface was discovered
which was not buoyed by this floating weed. The good ser-
vice it thus affords to vessels navigating near this stormy
land is evident; and it certainly has saved many a one from
being wrecked. I know few things more surprising than to
see this plant growing and flourishing amidst those great
breakers of the western ocean, which no mass of rock, let it
be ever so hard, can long resist. The stem is round, slimy,
and smooth, and seldom has a diameter of so much as an
inch. A few taken together are sufficiently strong to support
the weight of the large loose stones, to which in the inland
channels they grow attached; and yet some of these stones
were so heavy that when drawn to the surface, they could
scarcely be lifted into a boat by one person. Captain Cook,
in his second voyage, says, that this plant at Kerguelen Land
rises from a greater depth than twenty-four fathoms; "and
as it does not grow in a perpendicular direction, but makes a
very acute angle with the bottom, and much of it afterwards
spreads many fathoms on the surface of the sea, I am well
warranted to say that some of it grows to the length of sixty
fathoms and upwards." I do not suppose the stem of any

• Its geographical range is remarkably wide; it is found from the extreme
southern islets near Cape Horn, as far north on the eastern coast (accord-
ing to information given me by Mr. Stokes) as lat. 43°, — but on the west-
ern coast, as Dr. Hooker tells me, it extends to the R. San Francisco in
California, and perhaps even to Kamtschatka. We thus have an immense
range in latitude; and as Cook, who must have been well acquainted with
the species, found it at Kerguelen Land, no less than 140° in longitude.

256 CHARLES DARWIN

other plant attains so great a length as three hundred and
sixty feet, as stated by Captain Cook. Captain Fitz Roy,
moreover, found it growing7 up from the greater depth of
forty-five fathoms. The beds of this sea-weed, even when
of not great breadth, make excellent natural floating break-
waters. It is quite curious to see, in an exposed harbour,
how soon the waves from the open sea, as they travel through
the straggling stems, sink in height, and pass into smooth
water.

The number of living creatures of all Orders, whose exist-
ence intimately depends on the kelp, is wonderful. A great
volume might be written, describing the inhabitants of one
of these beds of sea-weed. Almost all the leaves, excepting
those that float on the surface, are so thickly incrusted with
corallines as to be of a white colour. We find exquisitely
delicate structures, some inhabited by simple hydra-like
polypi, others by more organized kinds, and beautiful com-
pound Ascidiae. On the leaves, also, various patelliform shells,
Trochi, uncovered molluscs, and some bivalves are attached.
Innumerable Crustacea frequent every part of the plant. On
shaking the great entangled roots, a pile of small fish, shells,
cuttle-fish, crabs of all orders, sea-eggs, star-fish, beautiful
Holuthuriae, Planariae, and crawling nereidous animals of a
multitude of forms, all fall out together. Often as I recurred
to a branch of the kelp, I never failed to discover animals
of new and curious structures. In Chiloe, where the kelp
does not thrive very well, the numerous shells, corallines, and
Crustacea are absent; but there yet remain a few of the
Flustraceae, and some compound Ascidiae; the latter, how-
ever, are of different species from those in Tierra del Fuego :
we see here the fucus possessing a wider range than the ani-
mals which use it as an abode. I can only compare these
great aquatic forests of the southern hemisphere with the
terrestrial ones in the intertropical regions. Yet if in any
country a forest was destroyed, I do not believe nearly so
many species of animals would perish as would here, from

7 Voyages of the Adventure and Beagle, vol. i. p, 363. — It appears that
sea-weed grows extremely quick. — Mr. Stephenson found (Wilson s Voyage
round Scotland, vol. ii. p. 228) that a rock uncovered only at spring-tides,
which had been chiselled smooth in November, on the following May, that is,
within six months afterwards, was thickly covered with Fucus digitatus two
feet, and F. esculentus six feet, in length.

the destruction of the kelp. Amidst the leaves of this plant
numerous species of fish live, which nowhere else could find
food or shelter; with their destruction the many cormorants
and other fishing birds, the otters, seals, and porpoises, would
soon perish also; and lastly, the Fuegian savage, the misera-
ble lord of this miserable land, would redouble his cannibal
feast, decrease in numbers, and perhaps cease to exist.

June 8th. — We weighed anchor early in the morning and
left Port Famine. Captain Fitz Roy determined to leave the
Strait of Magellan by the Magdalen Channel, which had not
long been discovered. Our course lay due south, down that
gloomy passage which I have before alluded to as appearing
to lead to another and worse world. The wind was fair, but
the atmosphere was very thick; so that we missed much
curious scenery. The dark ragged clouds were rapidly driven
over the mountains, from their summits nearly down to their
bases. The glimpses which we caught through the dusky
mass were highly interesting; jagged points, cones of snow,
blue glaciers, strong outlines, marked on a lurid sky, were
seen at different distances and heights. In the midst of such
scenery we anchored at Cape Turn, close to Mount Sarmi-
ento, which was then hidden in the clouds. At the base of
the lofty and almost perpendicular sides of our little cove
there was one deserted wigwam, and it alone reminded us
that man sometimes wandered into these desolate regions.
But it would be difficult to imagine a scene where he seemed
to have fewer claims or less authority. The inanimate works
of nature — rock, ice, snow, wind, and water — all warring
with each other, yet combined against man — here reigned in
absolute sovereignty.

June $th. — In the morning we were delighted by seeing
the veil of mist gradually rise from Sarmiento, and display it
to our view. This mountain, which is one of the highest in
Tierra del Fuego, has an altitude of 6800 feet. Its base, for
about an eighth of its total height, is clothed by dusky woods,
and above this a field of snow extends to the summit. These
vast piles of snow, which never melt, and seem destined to
last as long as the world holds together, present a noble and
even sublime spectacle. The outline of the mountain was
admirably clear and defined. Owing to the abundance of

light reflected from the white and glittering surface, no
shadows were cast on any part ; and those lines which inter-
sected the sky could alone be distinguished: hence the mass
stood out in the boldest relief. Several glaciers descended in
a winding course from the upper great expanse of snow to
the sea-coast : they may be likened to great frozen Niagaras ;
and perhaps these cataracts of blue ice are full as beautiful
as the moving ones of water. By night we reached the west-
ern part of the channel; but the water was so deep that no
anchorage could be found. We were in consequence obliged
to stand off and on in this narrow arm of the sea, during a
pitch-dark night of fourteen hours long.

June loth. — In the morning we made the best of our way
into the open Pacific. The western coast generally consists
of low, rounded, quite barren hills of granite and greenstone.
Sir J. Narborough called one part South Desolation, because
it is " so desolate a land to behold :" and well indeed might
he say so. Outside the main islands, there are numberless
scattered rocks on which the long swell of the open ocean
incessantly rages. We passed out between the East and West
Furies ; and a little farther northward there are so many
breakers that the sea is called the Milky Way. One sight of
such a coast is enough to make a landsman dream for a week
about shipwrecks, peril, and death; and with this sight we
bade farewell for ever to Tierra del Fuego.

The following discussion on the climate of the southern
parts of the continent with relation to its productions, on
the snow-line, on the extraordinarily low descent of the
glaciers, and on the zone of perpetual congelation in
the antarctic islands, may be passed over by any one
not interested in these curious subjects, or the final re-
capitulation alone may be read. I shall, however, here
give only an abstract, and must refer for details to the
Thirteenth Chapter and the Appendix of the former edition
of this work.

On the Climate and Productions of Tierra del Fuego and
of the South-west Coast. — The following table gives the
mean temperature of Tierra del Fuego, the Falkland Islands,
and, for comparison, that of Dublin: —

Dublin S3 21 N. 59.54 39.2 49.37

Hence we see that the central part of Tierra del Fuego is
colder in winter, and no less than 9^2° less hot in summer,
than Dublin. According to von Buch, the mean temperature
of July (not the hottest month in the year) at Saltenfiord
in Norway, is as high as 57°. 8, and this place is actually 13°
nearer the pole than Port Famine ! * Inhospitable as this
climate appears to our feelings, evergreen trees flourish
luxuriantly under it. Humming-birds may be seen sucking
the flowers, and parrots feeding on the seeds of the Winter's
Bark, in lat. 55° S. I have already remarked to what a
degree the sea swarms with living creatures; and the shells
(such as the Patellae, Fissurellae, Chitons, and Barnacles),
according to Mr. G. B. Sowerby, are of a much larger size
and of a more vigorous growth, than the analogous species in
the northern hemisphere. A large Voluta is abundant in
southern Tierra del Fuego and the Falkland Islands. At
Bahia Blanca, in lat. 39° S., the most abundant shells were
three species of Oliva (one of large size), one or two Volu-
tas, and a Terebra. Now, these are amongst the best char-
acterized tropical forms. It is doubtful whether even one
small species of Oliva exists on the southern shores of
Europe, and there are no species of the two other genera.
If a geologist were to find in lat. 39° on the coast of Portugal
a bed containing numerous shells belonging to three species
of Oliva, to a Voluta and Terebra, he would probably assert
that the climate at the period of their existence must have
been tropical; but judging from South America, such an
inference might be erroneous.

The equable, humid, and windy climate of Tierra del
Fuego extends, with only a small increase of heat, for many
degrees along the west coast of the continent. The forests

8 With respect to Tierra del Fuego, the results are deduced from the
observations by Capt. King (Geographical Journal, 1830), and those taken
on board the Beagle. For the Falkland Islands, I am indebted to Capt.
Sulivan for the mean of the mean temperature (reduced from careful
observation at midnight. 8 A. M., noon, and 8 p. M.) of the three hottest
months, viz., December, January, and February. The temperature of Dublin
is taken from Barton.

260 CHARLES DARWIN

for 600 miles northward of Cape Horn, have a very similar
aspect. As a proof of the equable climate, even for 300 or
400 miles still further northward, I may mention that in
Chiloe (corresponding in latitude with the northern parts
of Spain) the peach seldom produces fruit, whilst straw-
berries and apples thrive to perfection. Even the crops of
barley and wheat8 are often brought into the houses to be
dried and ripened. At Valdivia (in the same latitude of
40°, with Madrid) grapes and fi^s ripen, but are not cpm-
mon; olives seldom ripen even partially, and oranges not at
all. These fruits, in corresponding latitudes in Europe, are
well known to succeed to perfection; and even in this con-
tinent, at the Rio Negro, under nearly the same parallel
with Valdivia, sweet potatoes (convolvulus) are cultivated;
and grapes, figs, olives, oranges, water and musk melons,
produce abundant fruit. Although the humid and equable
climate of Chiloe, and of the coast northward and south-
ward of it, is so unfavourable to our fruits, yet the native
forests, from lat. 45° to 38°, almost rival in luxuriance those
of the glowing intertropical regions. Stately trees of many
kinds, with smooth and highly coloured barks, are loaded
by parasitical monocotyledonous plants; large and elegant
ferns are numerous, and arborescent grasses entwine the
trees into one entangled mass to the height of thirty or forty
feet above the ground. Palm-trees grow in lat 37° ; an arbor-
escent grass, very like a bamboo, in 40° ; and another closely
allied kind, of great length, but not erect, flourishes even as
far south as 45° S.

An equable climate, evidently due to the large area of sea
compared with the land, seems to extend over the greater
part of the southern hemisphere ; and, as a consequence, the
vegetation partakes of a semi-tropical character. Tree-ferns
thrive luxuriantly in Van Diemen's Land (lat. 45°), and I
measured one trunk no less than six feet in circumference.
An arborescent fern was found by Forster in New Zealand
in 46°, where orchideous plants are parasitical on the trees.
In the Auckland Islands, ferns, according to Dr. Dieffen-
bach 10 have trunks so thick and high that they may be almost

called tree-ferns ; and in these islands, and even as far south
as lat. 55° in the Macquarrie Islands, parrots abound.

On the Height of the Snow-line, and on the Descent of
the Glaciers in South America. — For the detailed authorities
for the following table, I must refer to the former edition : —

As the height of the plane of perpetual snow seems chiefly to*
be determined by the extreme heat of the summer, rather than
by the mean temperature of the year, we ought not to be sur-
prised at its descent in the Strait of Magellan, where the sum-
mer is so cool, to only 3500 or 4000 feet above the level of the
sea ; although in Norway, we must travel to between lat. 67°
and 70° N., that is, about 14° nearer the pole, to meet with
perpetual snow at this low level. The difference in height,
namely, about 9000 feet, between the snow-line on the Cor-
dillera behind Chiloe (with its highest points ranging from
only 5600 to 7500 feet) and in central Chile" (a distance of
only 9° of latitude), is truly wonderful. The land from the
southward of Chiloe to near Concepcion (lat. 37°) is hidden
by one dense forest dripping with moisture. The sky is
cloudy, and we have seen how badly the fruits of southern
Europe succeed. In central Chile, on the other hand, a little
northward of Concepcion, the sky is generally clear, rain does
not fall for the seven summer months, and southern Euro-
pean fruits succeed admirably ; and even the sugar-cane has
been cultivated.12 No doubt the plane of perpetual snow
undergoes the above remarkable flexure of 9000 feet, unpar-

uOn the Cordillera of central Chile, I believe the snow-line varies ex-
ceedingly in height in different summers. I was assured that during one
very dry and long summer, all the snow disappeared from Aconcagua,
although it attains the prodigious height of 23,000 feet. It is probable that
much of the snow at these great heights is evaporated rather than thawed.

facture profitable. In the valley of Quillota, south of Ingenio, I saw some

alleled in other parts of the world, not far from the latitude
of Concepcion, where the land ceases to be covered with for-
est-trees; for trees in South America indicate a rainy cli-
mate, and rain a clouded sky and little heat in summer.

The descent of glaciers to the sea must, I conceive, mainly
depend (subject, of course, to a proper supply of snow in the
upper region) on the lowness of the line of perpetual snow
on steep mountains near the coast. As the snow-line is so
low in Tierra del Fuego, we might have expected that many
of the glaciers would have reached the sea. Nevertheless,
I was astonished when I first saw a range, only from 3000 to
4000 feet in height, in the latitude of Cumberland, with every
valley filled with streams of ice descending to the sea-coast.
"Almost every arm of the sea, which penetrates to the interior
higher chain, not only in Tierra del Fuego, but on the coast
for 650 miles northwards, is terminated by " tremendous and
astonishing glaciers/' as described by one of the officers on
the survey. Great masses of ice frequently fall from these
icy cliffs, and the crash reverberates like the broadside of a
man-of-war through the lonely channels. These falls, as
noticed in the last chapter, produce great waves which break
on the adjoining coasts. It is known that earthquakes fre-
quently cause masses of earth to fall from sea-cliffs: how
terrific, then, would be the effect of a severe shock (and such
occur here13) on a body like a glacier, already in motion, and
traversed by fissures ! I can readily believe that the water
would be fairly beaten back out of the deepest channel, and
then, returning with an overwhelming force, would whirl
about huge masses of rock like so much chaff. In Eyre's
Sound, in the latitude of Paris, there are immense glaciers,
and yet the loftiest neighbouring mountain is only 6200 feet
high. In this Sound, about fifty icebergs were seen at one
time floating outwards, and one of them must have been at
least 168 feet in total height. Some of the icebergs were
loaded with blocks of no inconsiderable size, of granite and
other rocks, different from the clay-slate of the surrounding
mountains. The glacier furthest from the pole, surveyed
during the voyages of the Adventure and Beagle, is in lat.

Rafael, some Spanish missionaries14 encountered " many ice-
bergs, some great, some small, and others middle-sized," in
a narrow arm of the sea, on the 22nd of the month corre-
sponding with our June, and in a latitude corresponding with
that of the Lake of Geneva !

In Europe, the most southern glacier which comes down
to the sea is met with, according to Von Buch, on the coast
of Norway, in lat. 67°. Now, this is more than 20° of lati-
tude, or 1230 miles, nearer the pole than the Laguna de San
Rafael. The position of the glaciers at this place and in the
Gulf of Penas may be put even in a more striking point of
view, for they descend to the sea-coast within 7^2° of lati-
tude, or 450 miles, of a harbour, where three species of
Oliva, a Voluta, and a Terebra, are the commonest shells,
within less than 9° from where palms grow, within 4^° of
a region where the jaguar and puma range over the
plains, less than 2l/2° from arborescent grasses, and (look-

ing to the westward in the same hemisphere) less than 2°
from orchideous parasites, and within a single degree of
tree-ferns !

These facts are of high geological interest with respect to
the climate of the northern hemisphere at the period when
boulders were transported. I will not here detail how simply
the theory of icebergs being charged with fragments of rock,
explain the origin and position of the gigantic boulders of
eastern Tierra del Fuego, on the high plain of Santa Cruz,
and on the island of Chiloe. In Tierra del Fuego, the greater
number of boulders lie on the lines of old sea-channels, now
converted into dry valleys by the elevation of the land. They
are associated with a great unstratified formation of mud
and sand, containing rounded and angular fragments of all
sizes, which has originated M in the repeated ploughing up of
the sea-bottom by the stranding of icebergs, and by the mat-
ter transported on them. Few geologists now doubt that
those erratic boulders which lie near lofty mountains have
been pushed forward by the glaciers themselves, and that
those distant from mountains, and embedded in subaqueous
deposits, have been conveyed thither either on icebergs or
frozen in coast-ice. The connection between the transportal
of boulders and the presence of ice in some form, is strik-
ingly shown by their geographical distribution over the earth.
In South America they are not found further than 48° of
latitude, measured from the southern pole ; in North America
it appears that the limit of their transportal extends to 53^2°
from the northern pole ; but in Europe to not more than 40°
of latitude, measured from the same point. On the other
hand, in the intertropical parts of America, Asia, and Africa,
they have never been observed; nor at the Cape of Good
Hope, nor in Australia."

On the Climate and Productions of the Antarctic Islands.
— Considering the rankness of the vegetation in Tierra del
Fuego, and on the coast northward of it, the condition of the
islands south and south-west of America is truly surprising.

in the first edition, and in the Appendix to it. I have there shown that
the apparent exceptions to the absence of erratic boulders in certain hot
countries, are due to erroneous observations; several statements there
given I have since found confirmed by various authors.

THE VOYAGE OF THE BEAGLE 265

Sandwich Land, in the latitude of the north part of Scot-
land, was found by Cook, during the hottest month of the
year, " covered many fathoms thick with everlasting snow ; "
and there seems to be scarcely any vegetation. Georgia, an
island 96 miles long and 10 broad, in the latitude of York-
shire, " in the very height of summer, is in a manner wholly
covered with frozen snow." It can boast only of moss, some
tufts of grass, and wild burnet; it has only one land-bird
(Anthus correndera), yet Iceland, which is 10° nearer the
pole, has, according to Mackenzie, fifteen land-birds. The
South Shetland Islands, in the same latitude as the southern
half of Norway, possess only some lichens, moss, and a little
grass ; and Lieut. Kendall " found the bay, in which he was
at anchor, beginning to freeze at a period corresponding with
our 8th of September. The soil here consists of ice and
volcanic ashes interstratified; and at a little depth beneath
the surface it must remain perpetually congealed, for Lieut.
Kendall found the body of a foreign sailor which had long
been buried, with the flesh and all the features perfectly pre-
served. It is a singular fact, that on the two great continents
in the northern hemisphere (but not in the broken land of
Europe between them), we have the zone of perpetually
frozen undersoil in a low latitude — namely, in 56° in North
America at the depth of three feet,M and in 62° in Siberia at
the depth of twelve to fifteen feet — as the result of a directly
opposite condition of things to those of the southern hemi-
sphere. On the northern continents, the winter is rendered
excessively cold by the radiation from a large area of land
into a clear sky, nor is it moderated by the warmth-bringing
currents of the sea ; the short summer, on the other hand, is
hot. In the Southern Ocean the winter is not so excessively
cold, but the summer is far less hot, for the clouded sky sel-
dom allows the sun to warm the ocean, itself a bad absorbent
of heat ; and hence the mean temperature of the year, which
regulates the zone of perpetually congealed under-soil, is low.
It is evident that a rank vegetation, which does not so much
require heat as it does protection from intense cold, would
approach much nearer to this zone of perpetual congelation

under the equable climate of the southern hemisphere, than
under the extreme climate of the northern continents.

The case of the sailor's body perfectly preserved in the icy
soil of the South Shetland Islands (lat. 62° to 63° S.), in a
rather lower latitude than that (lat. 64° N.) under which
Pallas found the frozen rhinoceros in Siberia, is very inter-
esting. Although it is a fallacy, as I have endeavoured to
show in a former chapter, to suppose that the larger quadru-
peds require a luxuriant vegetation for their support, never-
theless it is important to find in the South Shetland Islands,
a frozen under-soil within 360 miles of the forest-clad islands
near Cape Horn, where, as far as the bulk of vegetation is
concerned, any number of great quadrupeds might be sup-
ported. The perfect preservation of the carcasses of the
Siberian elephants and rhinoceroses is certainly one of the
most wonderful facts in geology; but independently of the
imagined difficulty of supplying them with food from the
adjoining countries, the whole case is not, I think, so per-
plexing as it has generally been considered. The plains of
Siberia, like those of the Pampas, appear to have been formed
under the sea, into which rivers brought down the bodies
of many animals; of the greater number of these, only the
skeletons have been preserved, but of others the perfect car-
cass. Now, it is known that in the shallow sea on the Arctic
coast of America the bottom freezes,19 and does not thaw in
spring so soon as the surface of the land; moreover at
greater depths, where the bottom of the sea does not freeze,
the mud a few feet beneath the top layer might remain even
in summer below 32°, as in the case on the land with the soil
at the depth of a few feet. At still greater depths, the tem-
perature of the mud and water would probably not be low
enough to preserve the flesh; and hence, carcasses drifted
beyond the shallow parts near an Arctic coast, would have
only their skeletons preserved : now in the extreme northern
parts of Siberia bones are infinitely numerous, so that even
islets are said to be almost composed of them;20 and those
islets lie no less than ten degrees of latitude north of the
place where Pallas found the frozen rhinoceros. On the other

hand, a carcass washed by a flood into a shallow part of the
Arctic Sea, would be preserved for an indefinite period, if it
were soon afterwards covered with mud sufficiently thick to
prevent the heat of the summer-water penetrating to it ; and
if, when the sea-bottom was upraised into land, the covering
was sufficiently thick to prevent the heat of the summer air
and sun thawing and corrupting it.

Recapitulation. — I will recapitulate the principal facts with
regard to the climate, ice-action, and organic productions of
the southern hemisphere, transposing the places in imagina-
tion to Europe, with which we are so much better acquainted.
Then, near Lisbon, the commonest sea-shells, namely, three
species of Oliva, a Voluta, and a Terebra, would have a
tropical character. In the southern provinces of France,
magnificent forests, intwined by arborescent grasses and with
the trees loaded with parasitical plants, would hide the face
of the land. The puma and the jaguar would haunt the
Pyrenees. In the latitude of Mont Blanc, but on an island as
far westward as Central North America, tree-ferns and para-
sitical Orchidese would thrive amidst the thick woods. Even
as far north as central Denmark, humming-birds would be
seen fluttering about delicate flowers, and parrots feeding
amidst the evergreen woods ; and in the sea there, we should
have a Voluta, and all the shells of large size and vigorous
growth. Nevertheless, on some islands only 360 miles north-
ward of our new Cape Horn in Denmark, a carcass buried
in the soil (or if washed into a shallow sea, and covered up
with mud) would be preserved perpetually frozen. If some
bold navigator attempted to penetrate northward of these
islands, he would run a thousand dangers amidst gigantic
icebergs, on some of which he would see great blocks of rock
borne far away from their original site. Another island of
large size in the latitude of southern Scotland, but twice as
far to the west, would be " almost wholly covered with ever-
lasting snow," and would have each bay terminated by ice-
cliffs, whence great masses would be yearly detached: this
island would boast only of a little moss, grass, and burnet,
and a titlark would be its only land inhabitant. From our
new Cape Horn in Denmark, a chain of mountains, scarcely
half the height of the Alps, would run in a straight line due

268 CHARLES DARWIN

southward ; and on its western flank every deep creek of the
sea, or fiord, would end in " bold and astonishing glaciers."
These lonely channels would frequently reverberate with the
falls of ice, and so often would great waves rush along their
coasts; numerous icebergs, some as tall as cathedrals, and
occasionally loaded with " no inconsiderable blocks of rock,"
would be stranded on the outlying islets; at intervals violent
earthquakes would shoot prodigious masses of ice into the
waters below. Lastly, some missionaries attempting to pene-
trate a long arm of the sea, would behold the not lofty sur-
rounding mountains, sending down their many grand icy
streams to the sea-coast, and their progress in the boats would
be checked by the innumerable floating icebergs, some small
and some great ; and this would have occurred on our twenty-
second of June, and where the Lake of Geneva is now spread
out!91

31 In the former edition and Appendix, I have given some facts on the
transportal of erratic boulders and icebergs in the Antarctic Ocean. This
subject has lately been treated excellently by Mr. Hayes, in the Boston

one hundred miles distant from any land, and perhaps much more distant.
In the Appendix I have discussed at length the probability (at that time
hardly thought of) of icebergs, when stranded, grooving and polishing
rocks, like glaciers. This is now a very commonly received opinion; and
I cannot still avoid the suspicion that it is applicable even to such cases
as that of the Jura. Dr. Richardson has assured me that the icebergs off
North America push before them pebbles and sand, and leave the sub-
marine rocky flats quite bare; it is hardly possible to doubt that such
ledges must be polished and scored in the direction of the set of the pre-
vailing currents. Since writing that Appendix, I have seen in North
Wales (London Phil. Mag., vol. xxi. p. 180) the adjoining action of glaciers
and floating icebergs.

yULY s^rd. — The Beagle anchored late at night in the
bay of Valparaiso, the chief seaport of Chile. When
morning came, everything appeared delightful. After
Tierra del Fuego, the climate felt quite delicious — the atmos-
phere so dry, and the heavens so clear and blue with the sun
shining brightly, that all nature seemed sparkling with life.
The view from the anchorage is very pretty. The town is
built at the very foot of a range of hills, about 1600 feet high,
and rather steep. From its position, it consists of one long,
straggling street, which runs parallel to the beach, and wher-
ever a ravine comes down, the houses are piled up on each
side of it. The rounded hills, being only partially protected
by a very scanty vegetation, are worn into numberless little
gullies, which expose a singularly bright red soil. From this
cause, and from the low whitewashed houses with tile roofs,
the view reminded me of St. Cruz in Teneriffe. In a north-
westerly direction there are some fine glimpses of the Andes :
but these mountains appear much grander when viewed from
the neighbouring hills ; the great distance at which they are
situated can then more readily be perceived. The volcano of
Aconcagua is particularly magnificent. This huge and irreg-
ularly conical mass has an elevation greater than that of
Chimborazo ; for, from measurements made by the officers in
the Beagle, its height is no less than 23,000 feet. The Cor-
dillera, however, viewed from this point, owe the greater part
of their beauty to the atmosphere through which they are
seen. When the sun was setting in the Pacific, it was

269

270 CHARLES DARWIN

admirable to watch how clearly their rugged outlines could
be distinguished, yet how varied and how delicate were the
shades of their colour.

I had the good fortune to find living here Mr. Richard
Corfield, an old schoolfellow and friend, to whose hospitality
and kindness I was greatly indebted, in having afforded me
a most pleasant residence during the Beagle's stay in Chile.
The immediate neighbourhood of Valparaiso is not very pro-
ductive to the naturalist. During the long summer the wind
blows steadily from the southward, and a little off shore, so
that rain never falls; during the three winter months, how-
ever, it is sufficiently abundant. The vegetation in conse-
quence is very scanty : except in some deep valleys, there are
no trees, and only a little grass and a few low bushes are
scattered over the less steep parts of the hills. When we
reflect, that at the distance of 350 miles to the south, this side
of the Andes is completely hidden by one impenetrable forest,
the contrast is very remarkable. I took several long walks
while collecting objects of natural history.. The country is
pleasant for exercise. There are many very beautiful flow-
ers; and, as in most other dry climates, the plants and shrubs
possess strong and peculiar odours — even one's clothes by
brushing through them became scented. I did not cease from
wonder at finding each succeeding day as fine as the fore-
going. What a difference does climate make in the enjoy-
ment of life! How opposite are the sensations when view-
ing black mountains half enveloped in clouds, and seeing
another range through the light blue haze of a fine day ! The
one for a time may be very sublime; the other is all gaiety
and happy life.

August i^th. — I set out on a riding excursion, for the
purpose of geologizing the basal parts of the Andes, which
alone at this time of the year are not shut up by the winter
snow. Our first day's ride was northward along the sea-
coast. After dark we reached the Hacienda of Quintero,
the estate which formerly belonged to Lord Cochrane. My
object in coming here was to see the great beds of shells,
which stand some yards above the level of the sea, and are
burnt for lime. The proofs of the elevation of this whole
line of coast are unequivocal: at the height of a few hun-

THE VOYAGE OF THE BEAGLE 271

dred feet old-looking shells are numerous, and I found some
at 1300 feet. These shells either lie loose on the surface, or
are embedded in a reddish-black vegetable mould. I was
much surprised to find under the microscope that this vege-
table mould is really marine mud, full of minute particles of
organic bodies.

i$th. — We returned towards the valley of Quillota. The
country was exceedingly pleasant; just such as poets would
call pastoral : green open lawns, separated by small valleys
with rivulets, and the cottages, we may suppose of the shep-
herds, scattered on the hill-sides. We were obliged to cross
the ridge of the Chilicauquen. At its base there were many
fine evergreen forest-trees, but these flourished only in the
ravines, where there was running water. Any person who
had seen only the country near Valparaiso, would never have
imagined that there had been such picturesque spots in Chile.
As soon as we reached the brow of the Sierra, the valley of
Quillota was immediately under our feet. The prospect was
one of remarkable artificial luxuriance. The valley is very
broad and quite flat, and is thus easily irrigated in all parts.
The little square gardens are crowded with orange and olive
trees, and every sort of vegetable. On each side huge bare
mountains rise, and this from the contrast renders the patch-
work valley the more pleasing. Whoever called " Val-
paraiso " the " Valley of Paradise," must have been thinking
of Quillota. We crossed over to the Hacienda de San Isidro,
situated at the very foot of the Bell Mountain.

Chile, as may be seen in the maps, is a narrow strip of
land between the Cordillera and the Pacific; and this strip
is itself traversed by several mountain-lines, which in this
part run parallel to the great range. Between these outer
lines and the main Cordillera, a succession of level basins,
generally opening into each other by narrow passages, extend
far to the southward : in these, the principal towns are situ-
ated, as San Felipe, Santiago, San Fernando. These basins
or plains, together with the transverse flat valleys (like that '
of Quillota) which connect them with the coast, I have no
doubt are the bottoms of ancient inlets and deep bays, such
as at the present day intersect every part of Tierra del Fuego
and the western coast. Chile must formerly have resembled

272 CHARLES DARWIN

the latter country in the configuration of its land and water.
The resemblance was occasionally shown strikingly when a
level fog-bank covered, as with a mantle, all the lower parts
of the country: the white vapour curling into the ravines,
beautifully represented little coves and bays; and here and
there a solitary hillock peeping up, showed that it had for-
merly stood there as an islet. The contrast of these flat
valleys and basins with the irregular mountains, gave the
scenery a character which to me was new and very inter-
esting.

From the natural slope to seaward of these plains, they
are very easily irrigated, and in consequence singularly fer-
tile. Without this process the land would produce scarcely
anything, for during the whole summer the sky is cloudless.
The mountains and hills are dotted over with bushes and
low trees, and excepting these the vegetation is very scanty.
Each landowner in the valley possesses a certain portion of
hill-country, where his half-wild cattle, in considerable num-
bers, manage to find sufficient pasture. Once every year there
is a grand " rodeo," when all the cattle are driven down,
counted, and marked, and a certain number separated to be
fattened in the irrigated fields. Wheat is extensively culti-
vated, and a good deal of Indian corn: a kind of bean is,
however, the staple article of food for the common labourers.
The orchards produce an overflowing abundance of peaches,
figs, and grapes. With all these advantages, the inhabitants
of the country ought to be much more prosperous than they
are.

i6th. — The mayor-domo of the Hacienda was good enough
to give me a guide and fresh horses ; and in the morning we
set out to ascend the Campana, or Bell Mountain, which is
6400 feet high. The paths were very bad, "but both the
geology and scenery amply repaid the trouble. We reached,
by the evening, a spring called the Agua del Guanaco, which
is situated at a great height. This must be an old name,
for it is very many years since a guanaco drank its waters.
During the ascent I noticed that nothing but bushes grew
on the northern slope, whilst on the southern slope there was
a bamboo about fifteen feet high. In a few places there were
palms, and I was surprised to see one at an elevation of at

THE VOYAGE OF THE BEAGLE 273

least 4500 feet. These palms are, for their family, ugly trees.
Their stem is very large, and of a curious form, being thicker
in the middle than at the base or top. They are excessively
numerous in some parts of Chile, and valuable on account of
a sort of treacle made from the sap. On one estate near
Petorca they tried to count them, but failed, after having
numbered several hundred thousand. Every year in the early
spring, in August, very many are cut down, and when the
trunk is lying on the ground, the crown of leaves is lopped
off. The sap then immediately begins to flow from the upper
end, and continues so doing for some months : it is, how-
ever, necessary that a thin slice should be shaved off from
that end every morning, so as to expose a fresh surface. A
good tree will give ninety gallons, and all this must have
been contained in the vessels of the apparently dry trunk.
It is said that the sap flows much more quickly on those
days when the sun is powerful ; and likewise, that it is abso-
lutely necessary to take care, in cutting down the tree, that
it should fall with its head upwards on the side of the hill;
for if it falls down the slope, scarcely any sap will flow;
although in that case one would have thought that the action
would have been aided, instead of checked, by the force of
gravity. The sap is concentrated by boiling, and is then
called treacle, which it very much resembles in taste.

We unsaddled our horses near the spring, and prepared to
pass the night. The evening was fine, and the atmosphere so
clear, that the masts of the vessels at anchor in the bay of
Valparaiso, although no less than twenty-six geographical
miles distant, could be distinguished clearly as little black
streaks. A ship doubling the point under sail, appeared as
a bright white speck. Anson expresses much surprise, in his
voyage, at the distance at which his vessels were discovered
from the coast ; but he did not sufficiently allow for the height
of the land, and the great transparency of the air.

The setting of the sun was glorious; the valleys being
black whilst the snowy peaks of the Andes yet retained a
ruby tint. When it was dark, we made a fire beneath a little
arbour of bamboos, fried our charqui (or dried slips of beef),
took our mate, and were quite comfortable. There is an
inexpressible charm in thus living in the open air. The even-

274 CHARLES DARWIN

ing was calm and still; — the shrill noise of the mountain
bizcacha, and the faint cry of a goatsucker, were occa-
sionally to be heard. Besides these, few birds, or even
insects, frequent these dry, parched mountains.

August ijth. — In the morning we climbed up the rough
mass of greenstone which crowns the summit. This rock, as
frequently happens, was much shattered and broken into
huge angular fragments. I observed, however, one remark-
able circumstance, namely, that many of the surfaces pre-
sented every degree of freshness — some appearing as if
. broken the day before, whilst on others lichens had either
, just become, or had long grown, attached. I so fully believed
that this was owing to the frequent earthquakes, that I felt
inclined to hurry from below each loose pile. As one might
very easily be deceived in a fact of this kind, I doubted its
accuracy, until ascending Mount Wellington, in Van Die-
men's Land, where earthquakes do not occur ; and there I saw
the summit of the mountain similarly composed and similarly
shattered, but all the blocks appeared as if they had been
hurled into their present position thousands of years ago.

We spent the day on the summit, and I never enjoyed one
more thoroughly. Chile, bounded by the Andes and the
Pacific, was seen as in a map. The pleasure from the scenery,
in itself beautiful, was heightened by the many reflections
which arose from the mere view of the Campana range with
its lesser parallel ones, and of the broad valley of Quillota
directly intersecting them. Who can avoid wondering at the
force which has upheaved these mountains, and even more
so at the countless ages which it must have required to have
broken through, removed, and levelled whole masses of them?
It is well in this case to call to mind the vast shingle and
sedimentary beds of Patagonia, which, if heaped on the Cor-
dillera, would increase its height by so many thousand feet.
When in that country, I wondered how any mountain-chain
could have supplied such masses, and not have been utterly
obliterated. We must not now reverse the wonder, and doubt
whether all-powerful time can grind down mountains — even
the gigantic Cordillera — into gravel and mud.

The appearance of the Andes was different from that
which I had expected. The lower line pf the snow was of

THE VOYAGE OF THE BEAGLE 275

course horizontal, and to this line the even summits of the
range seemed quite parallel. Only at long intervals, a group
of points or a single cone showed where a volcano had
existed, or does now exist. Hence the range resembled a
great solid wall, surmounted here and there by a tower, and
making a most perfect barrier to the country.

Almost every part of the hill had been drilled by attempts
to open gold-mines: the rage for mining has left scarcely
a spot in Chile unexamined. I spent the evening as before,
talking round the fire with my two companions. The Guasos
of Chile, who correspond to the Gauchos of the Pampas, are,
however, a very different set of beings. Chile is the more
civilized of the two countries, and the inhabitants, in conse-
quence, have lost much individual character. Gradations in
rank are much more strongly marked: the Guaso does not
by any means consider every man his equal ; and I was quite
surprised to find that my companions did not like to eat at
the same time with myself. This feeling of inequality is a
necessary consequence of the existence of an aristocracy of
wealth. It is said that some few of the greater landowners
possess from five to ten thousand pounds sterling per annum :
an inequality of riches which I believe is not met with in
any of the cattle-breeding countries eastward of the Andes.
A traveller does not here meet that unbounded hospitality
which refuses all payment, but yet is so kindly offered that
no scruples can be raised in accepting it. Almost every house
in Chile will receive you for the night, but a trifle is expected
to be given in the morning ; even a rich man will accept two
or three shillings. The Gaucho, although he may be a cut-
throat, is a gentleman; the Guaso is in few respects better,
but at the same time a vulgar, ordinary fellow. The two men,
although employed much in the same manner, are different in
their habits and attire; and the peculiarities of each are
universal in their respective countries. The Gaucho seems
part of his horse, and scorns to exert himself except when
on his back : the Guaso may be hired to work as a labourer in
the fields. The former lives entirely on animal food ; the latter
almost wholly on vegetable. We do not here see the white
boots, the broad drawers and scarlet chilipa ; the picturesque
costume of the Pampas. Here, common trousers are pro-

276 CHARLES DARWIN

tected by black and green worsted leggings. The poncho,
however, is common to bothu The chief pride of the Guaso
lies in his spurs, which are absurdly large. I measured one
which was six inches in the diameter of the rowel, and the
rowel itself contained upwards of thirty points. The stirrups
are on the same scale, each consisting of a square, carved
block of wood, hollowed out, yet weighing three or four
pounds. The Guaso is perhaps more expert with the lazo
than the Gaucho; but, from the nature of the country, he
does not know the use of the bolas.

August i8th. — We descended the mountain, and passed
some beautiful little spots, with rivulets and fine trees. Hav-
ing slept at the same hacienda as before, we rode during the
two succeeding days up the valley, and passed through Quil-
lota, which is more like a collection of nursery-gardens than
a town. The orchards were beautiful, presenting one mass
of peach-blossoms. I saw, also, in one or two places the
date-palm ; it is a most stately tree ; and I should think a
group of them in their native Asiatic or African deserts must
be superb. We passed likewise San Felipe, a pretty strag-
gling town like Quillota. The valley in this part expands into
one of those great bays or plains, reaching to the foot of the
Cordillera, which have been mentioned as forming so curious
a part of the scenery of Chile. In the evening we reached
the mines of Jajuel, situated in a ravine at the flank of the
great chain. I stayed here five days. My host, the superin-
tendent of the mine, was a shrewd but rather ignorant Cor-
nish miner. He had married a Spanish woman, and did not
mean to return home; but his admiration for the mines of
Cornwall remained unbounded. Amongst many other ques-
tions, he asked me, " Now that George Rex is dead, how
many more of the family of Rexes are yet alive? " This Rex
certainly must be a relation of the great author Finis, who
wrote all books !

These mines are of copper, and the ore is all shipped to
Swansea, to be smelted. Hence the mines have an aspect
singularly quiet, as compared to those in England: here no
smoke, furnaces, or great steam-engines, disturb the solitude
of the surrounding mountains.

The Chilian government, or rather the old Spanish law,

THE VOYAGE OF THE BEAGLE 277

encourages by every method the searching for mines. The
discoverer may work a mine on any ground, by paying five
shillings; and before paying this he may try, even in the
garden of another man, for twenty days.

It is now well known that the Chilian method of mining
is the cheapest. My host says that the two principal improve-
ments introduced by foreigners have been, first, reducing by
previous roasting the copper pyrites — which, being the com-
mon ore in Cornwall, the English miners were astounded on
their arrival to find thrown away as useless : secondly, stamp-
ing and washing the scoriae from the old furnaces — by which
process particles of metal are recovered in abundance. I have
actually seen mules carrying to the coast, for transportation
to England, a cargo of such cinders. But the first case is
much the most curious. The Chilian miners were so con-
vinced that copper pyrites contained not a particle of copper,
that they laughed at the Englishmen for their ignorance,
who laughed in turn, and bought their richest veins for a
few dollars. It is very odd that, in a country where mining
had been extensively carried on for many years, so simple a
process as gently roasting the ore to expel the sulphur pre-
vious to smelting it, had never been discovered. A few im-
provements have likewise been introduced in some of the
simple machinery; but even to the present day, water is
removed from some mines by men carrying it up the shaft in
leathern bags !

The labouring men work very hard. They have little time
allowed for their meals, and during summer and winter they
begin when it is light, and leave off at dark. They are paid
one pound sterling a month, and their food is given them:
this for breakfast consists of sixteen figs and two small loaves
of bread ; for dinner, boiled beans ; for supper, broken roasted
wheat grain. They scarcely ever taste meat ; as, with the
twelve pounds per annum, they have to clothe themselves, and
support their families. The miners who work in the mine
itself have twenty-five shillings per month, and are allowed
a little charqui. But these men come down from their bleak
habitations only once in every fortnight or three weeks.

During my stay here I thoroughly enjoyed scrambling
about these huge mountains. The geology, as might have

278 CHARLES DARWIN

been expected, was very interesting. The shattered and
baked rocks, traversed by innumerable dykes of greenstone,
showed what commotions had formerly taken place. The
scenery was much the same as that near the Bell of Quil-
lota — dry barren mountains, dotted at intervals by bushes
with a scanty foliage. The cactuses, or rather opuntias,
were here very numerous. I measured one of a spherical
figure, which, including the spines, was six feet and four
inches in circumference. The height of the common cylin-
drical, branching kind, is from twelve to fifteen feet, and
the girth (with spines) of the branches between three and
four feet.

A heavy fall of snow on the mountains prevented me,
during the last two days, from making some interesting
excursions. I attempted to reach a lake which the inhab-
itants, from some unaccountable reason, believe to be an arm
of the sea. During a very dry season, it was proposed to
attempt cutting a channel from it for the sake of the water,
but the padre, after a consultation, declared it was too dan-
gerous, as all Chile would be inundated, if, as generally
supposed, the lake was connected with the Pacific. We
ascended to a great height, but becoming involved in the
snow-drifts failed in reaching this wonderful lake, and had
some difficulty in returning. I thought we should have lost
our horses; for there was no means of guessing how deep
the drifts were, and the animals, when led, could only move
by jumping. The black sky showed that a fresh snow-
storm was gathering, and we therefore were not a little glad
when we escaped. By the time we reached the base the
storm commenced, and it was lucky for us that this did not
happen three hours earlier in the day.

August 26th. — We left Jajuel and again crossed the basin
of San Felipe. The day was truly Chilian: glaringly bright,
and the atmosphere quite clear. The thick and uniform
covering of newly fallen snow rendered the view of the vol-
cano of Aconcagua and the main chain quite glorious. We
were now on the road to Santiago, the capital of Chile. We
crossed the Cerro del Talguen, and slept at a little rancho.
The host, talking about the state of Chile as compared to
other countries, was very humble : " Some see with two eyes,

THE VOYAGE OF THE BEAGLE 279

and some with one, but for my part I do not think that Chile
sees with any."

August 2?th. — After crossing many low hills we descended
into the small land-locked plain of Guitron. In the basins,
such as this one, which are elevated from one thousand to
two thousand feet above the sea, two species of acacia, which
are stunted in their forms, and stand wide apart from each
other, grow in large numbers. These trees are never found
near the sea-coast ; and this gives another characteristic
feature to the scenery of these basins. We crossed a low
ridge which separates Guitron from the great plain on which
Santiago stands. The view was here pre-eminently striking:
the dead level surface, covered in parts by woods of acacia,
and with the city in the distance, abutting horizontally
against the base of the Andes, whose snowy peaks were
bright with the evening sun. At the first glance of this
view, it was quite evident that the plain represented the
extent of a former inland sea. As soon as we gained the
level road we pushed our horses into a gallop, and reached
the city before it was dark.

I stayed a week in Santiago, and enjoyed myself very
much. In the morning I rode to various places on the plain,
and in the evening dined with several of the English mer-
chants, whose hospitality at this place is well known. A
never-failing source of pleasure was to ascend the little
hillock of rock (St. Lucia) which projects in the middle of
the city. The scenery certainly is most striking, and, as I
have said, very peculiar. I am informed that this same
character is common to the cities on the great Mexican
platform. Of the town I have nothing to say in detail: it is
not so fine or so large as Buenos Ayres, but is built after the
same model. I arrived here by a circuit to the north; so I
resolved to return to Valparaiso by a rather longer excur-
sion to the south of the direct road.

September $th. — By the middle of the day we arrived at
one of the suspension bridges, made of hide, which cross the
Maypu, a large turbulent river a few leagues southward of
Santiago. These bridges are very poor affairs. The road,
following the curvature of the suspending ropes, is made of
bundles of sticks placed close together. It was full of holes,

280 CHARLES DARWIN

and oscillated rather fearfully, even with the weight of a
man leading his horse. In the evening we reached a com-
fortable farm-house, where there were several very pretty
senoritas. They were much horrified at my having entered
one of their churches out of mere curiosity. They asked
me, " Why do you not become a Christian — for our religion
is certain ? " I assured them I was a sort of Christian ; but
they would not hear of it — appealing to my own words, " Do
not your padres, your very bishops, marry? " The absurdity
of a bishop having a wife particularly struck them: they
scarcely knew whether to be most amused or horror-struck
at such an enormity.

6th. — We proceeded due south, and slept at Rancagua.
The road passed over the level but narrow plain, bounded on
one side by lofty hills, and on the other by the Cordillera.
The next day we turned up the valley of the Rio Cachapual,
in which the hot-baths of Cauquenes, long celebrated for
their medicinal properties, are situated. The suspension
bridges, in the less frequented parts, ar generally taken down
during the winter when the rivers are low. Such was the
case in this valley, and we were therefore obliged to cross
the stream on horseback. This is rather disagreeable, for
the foaming water, though not deep, rushes so quickly over
the bed of large rounded stones, that one's head becomes
quite confused, and it is difficult even to perceive whether
the horse is moving onward or standing still. In summer,
when the snow melts, the torrents are quite impassable ; their
strength and fury are then extremely great, as might be
plainly seen by the marks which they had left. We reached
the baths in the evening, and stayed there five days, being
confined the two last by heavy rain. The buildings consist
of a square of miserable little novels, each with a single table
and bench. They are situated in a narrow deep valley just
without the central Cordillera. It is a quiet, solitary spot,
with a good deal of wild beauty.

The mineral springs of Cauquenes burst forth on a line of
dislocation, crossing a mass of stratified rock, the whole
of which betrays the action of heat. A considerable quantity
of gas is continually escaping from the same orifices with
the water. Though the springs are only a few yards apart,

THE VOYAGE OP THE BEAGLB 281

they have very different temperature ; and this appears to be
the result of an unequal mixture of cold water: for those
with the lowest temperature have scarcely any mineral taste.
After the great earthquake of 1822 the springs ceased, and
the water did not return for nearly a year. They were also
much affected by the earthquake of 1835; the temperature
being suddenly changed from 118° to g2°.1 It seems probable
that mineral waters rising deep from the bowels of the earth,
would always be more deranged by subterranean disturbances
than those nearer the surface. The man who had charge of
the baths assured me that in summer the water is hotter and
more plentiful than in winter. The former circumstance I
should have expected, from the less mixture, during the dry
season, of cold water; but the latter statement appears very
strange and contradictory. The periodical increase during
the summer, when rain never falls, can, I think, only be
accounted for by the melting of the snow : yet the mountains
which are covered by snow during that season, are three or
four leagues distant from the springs. I have no reason to
doubt the accuracy of my informer, who, having lived on
the spot for several years, ought to be well acquainted with
the circumstance, — which, if true, certainly is very curious:
for we must suppose that the snow-water, being conducted
through porous strata to the regions of heat, is again thrown
up to the surface by the line of dislocated and injected rocks
at Cauquenes; and the regularity of the phenomenon would
seem to indicate that in this district heated rock occurred at
a depth not very great.

One day I rode up the valley to the farthest inhabited
spot. Shortly above that point, the Cachapual divides into
two deep tremendous ravines, which penetrate directly into
the great range. I scrambled up a peaked mountain, prob-
ably more than six thousand feet high. Here, as indeed
everywhere else, scenes of the highest interest presented
themselves. It was by one of these ravines, that Pincheira
entered Chile and ravaged the neighbouring country. This
is the same man whose attack on an estancia at the Rio Negro
I have described. He was a renegade half-caste Spaniard,
who collected a great body of Indians together and estab-

lished himself oy a stream in the Pampas, which place none
of the forces sent after him could ever discover. From this
point he used to sally forth, and crossing the Cordillera by
passes hitherto unattempted, he ravaged the farm-houses
and drove the cattle to his secret rendezvous. Pincheira was
a capital horseman, and he made all around him equally
good, for he invariably shot any one who hesitated to follow
him. It was against this man, and other wandering Indian
tribes, that Rosas waged the war of extermination.

September ijth. — We left the baths of Cauquenes, and,
rejoining the main road, slept at the Rio Clara. From this
place we rode to the town of San Fernando. Before arriving
there, the last land-locked basin had expanded into a great
plain, which extended so far to the south, that the snowy
summits of the more distant Andes were seen as if above the
horizon of the sea. San Fernando is forty leagues from San-
tiago; and it was my farthest point southward; for we here
turned at right angles towards the coast. We slept at the
gold-mines of Yaquil, which are worked by Mr. Nixon, an
American gentleman, to whose kindness I was much in-
debted during the four days I stayed at his house. The next
morning we rode to the mines, which are situated at the
distance of some leagues, near the summit of a lofty hill. On
the way we had a glimpse of the lake Tagua-tagua, cele-
brated for its floating islands, which have been described by
M. Gay.a They are composed of the stalks of various dead
plants intertwined together, and on the surface of which
other living ones take root. Their form is generally circular,
and their thickness from four to six feet, of which the
greater part is immersed in the water. As the wind blows,
they pass from one side of the lake to the other, and often
carry cattle and horses as passengers.

When we arrived at the mine, I was struck by the pale
appearance of many of the men, and inquired from Mr.
Nixon respecting their condition. The mine is 450 feet deep,
and each man brings up about 200 pounds weight of stone.
With this load they have to climb up the alternate notches cut
in the trunks of trees, placed in a zigzag line up the shaft.

* Annales des Sciences Naturelles, March, 1833. M. Gay, a zealous and
able naturalist, was then occupied in studying every branch of natural
history throughout the kingdom of Chile.

THE VOYAGE OF THE BEAGLE 283

Even beardless young men, eighteen and twenty years old,
with little muscular development of their bodies (they are
quite naked excepting drawers) ascend with this great load
from nearly the same depth. A strong man, who is not
accustomed to this labour, perspires most profusely, with
merely carrying up his own body. With this very severe
labour, they live entirely on boiled beans and bread. They
would prefer having bread alone; but their masters, finding
that they cannot work so hard upon this, treat them like
horses, and make them eat the beans. Their pay is here
rather more than at the mines of Jajuel, being from 24 to 28
shillings per month. They leave the mine only once in three
weeks ; when they stay with their families for two days. One
of the rules of this mine sounds very harsh, but answers
pretty well for the master. The only method of stealing gold
is to secrete pieces of the ore, and take them out as occasion
may offer. Whenever the major-domo finds a lump thus
hidden, its full value is stopped out of the wages of all the
men ; who thus, without they all combine, are obliged to keep
watch over each other.

When the ore is brought to the mill, it is ground into an
impalpable powder; the process of washing removes all the
lighter particles, and amalgamation finally secures the gold-
dust. The washing, when described, sounds a very simple
process; but it is beautiful to see how the exact adaptation of
the current of water to the specific gravity of the gold, so
easily separates the powdered matrix from the metal. The
mud which passes from the mills is collected into pools, where
it subsides, and every now and then is cleared out, and thrown
into a common heap. A great deal of chemical action then
commences, salts of various kinds effloresce on the surface,
and the mass becomes hard. After having been left for a year
or two, and then rewashed, it yields gold; and this process
may be repeated even six or seven times; but the gold each
time becomes less in quantity, and the intervals required (as
the inhabitants say, to generate the metal) are longer. There
can be no doubt that the chemical action, already mentioned,
each time liberates fresh gold from some combination. The
discovery of a method to effect this before the first grinding,
would without doubt raise the value of gold-ores many fold.

284 CHARLES DARWIN

It is curious to find how the minute particles of gold, being
scattered about and not corroding, at last accumulate in
some quantity. A short time since a few miners, being out of
work, obtained permission to scrape the ground round the
house and mills ; they washed the earth thus got together, and
so procured thirty dollars' worth of gold. This is an exact
counterpart of what takes place in nature. Mountains suffer
degradation and wear away, and with them the metallic veins
which they contain. The hardest rock is worn into impalpa-
ble mud, the ordinary metals oxidate, and both are removed ;
but gold, platina, and a few others are nearly indestructible,
and from their weight, sinking to the bottom, are left behind.
After whole mountains have passed through this grinding
mill, and have been washed by the hand of nature, the residue
becomes metalliferous, and man finds it worth his while to
complete the task of separation.

Bad as the above treatment of the miners appears, it is
gladly accepted of by them; for the condition of the labour-
ing agriculturists is much worse. Their wages are lower, and
they live almost exclusively on beans. This poverty must be
chiefly owing to the feudal-like system on which the land is
tilled: the landowner gives a small plot of ground to the
labourer, for building on and cultivating, and in return has
his services (or those of a proxy) for every day of his life,
without any wages. Until a father has a grown-up son, who
can by his labour pay the rent, there is no one, except on
occasional days, to take care of his own patch of ground.
Hence extreme poverty is very common among the labouring
classes in this country.

There are some old Indian ruins in this neighbourhood,
and I was shown one of the perforated stones, which Molina
mentions as being found in many places in considerable
numbers. They are of a circular flattened form, from five to
six inches in diameter, with a hole passing quite through the
centre. It has generally been supposed that they were used
as heads to clubs, although their form does not appear at all
well adapted for that purpose. Burchell8 states that some
of the tribes in Southern Africa dig up roots by the aid of a
stick pointed at one end, the force and weight of which are

» Burchell's Travels, vol. ii. p. 45.

THE VOYAGE OF THE BEAGLE 285

increased by a round stone with a hole in it, into which the
other end is firmly wedged. It appears probable that the
Indians of Chile formerly used some such rude agricultural
instrument.

One day, a German collector in natural history, of the
name of Renous, called, and nearly at the same time an old
Spanish lawyer. I was amused at being told the conversation
which took place between them. Renous speaks Spanish so
well, that the old lawyer mistook him for a Chilian. Renous,
alluding to me, asked him what he thought of the King of
England sending out a collector to their country, to pick up
lizards and beetles, and to break stones ? The old gentleman
thought seriously for some time, and then said, " It is not
well, — hay un goto encerrado aqui (there is a cat shut up
here). No man is so rich as to send out people to pick up
such rubbish. I do not like it: if one of us were to go and
do such things in England, do not you think the King of
England would very soon send us out of his country ? " And
this old gentleman, from his profession, belongs to the better
informed and more intelligent classes ! Renous himself, two
or three years before, left in a house at San Fernando some
caterpillars, under charge of a girl to feed, that they might
turn into butterflies. This was rumoured through the town,
and at last the padres and governor consulted together, and
agreed it must be some heresy. Accordingly, when Renous
returned, he was arrested.

September ipth. — We left Yaquil, and followed the flat
valley, formed like that of Quillota, in which the Rio Tin-
deridica flows. Even at these few miles south of Santiago
the climate is much damper; in consequence there are fine
tracts of pasturage, which are not irrigated. (20th.) We
followed this valley till it expanded into a great plain, which
reaches from the sea to the mountains west of Rancagua.
We shortly lost all trees and even bushes ; so that the inhabi-
tants are nearly as badly off for firewood as those in the Pam-
pas. Never having heard of these plains, I was much
surprised at meeting with such scenery in Chile. The plains
belong to more than one series of different elevations, and
they are traversed by broad flat-bottomed valleys; both of
which circumstances, as in Patagonia, bespeak the action of

286 CHARLES DARWIN

the sea on gently rising land. In the steep cliffs bordering
these valleys, there are some large caves, which no doubt
were originally formed by the waves: one of these is cele-
brated under the name of Cueva del Obispo ; having formerly
been consecrated. During the day I felt very unwell, and
from that time till the end of October did not recover.

September 22nd. — We continued to pass over green plains
without a tree. The next day we arrived at a house near
Navedad, on the sea-coast, where a rich Haciendero gave us
lodgings. I stayed here the two ensuing days, and although
very unwell, managed to collect from the tertiary formation
some marine shells.

24th. — Our course was now directed towards Valparaiso,
which with great difficulty I reached on the 27th, and was there
confined to my bed till the end of October. During this time
I was an inmate in Mr. Corfield's house, whose kindness to
me I do not know how to express.

I will here add a few observations on some of the animals
and birds of Chile. The Puma, or South American Lion, is
not uncommon. This animal has a wide geographical range ;
being found from the equatorial forests, throughout the
deserts of Patagonia, as far south as the damp and cold
latitudes (53° to 54°) of Tierra del Fuego. I have seen its
footsteps in the Cordillera of central Chile, at an elevation of
at least 10,000 feet. In La Plata the puma preys chiefly on
deer, ostriches, bizcacha, and other small quadrupeds ; it there
seldom attacks cattle or horses, and most rarely man. In
Chile, however, it destroys many young horses and cattle,
owing probably to the scarcity of other quadrupeds : I heard,
likewise, of two men and a woman who had been thus killed.
It is asserted that the puma always kills its prey by springing
on the shoulders, and then drawing back the head with one
of its paws, until the vertebrae break: I have seen in Pata-
gonia the skeletons of guanacos, with their necks thus
dislocated.

The puma, after eating its fill, covers the carcass with
many large bushes, and lies down to watch it. This habit is
often the cause of its being discovered; for the condors
wheeling in the air every now and then descend to partake

THE VOYAGE OF THE BEAGLE 287

of the feast, and being angrily driven away, rise all together
on the wing. The Chileno Guaso then knows there is a lion
watching his prey — the word is given — and men and dogs
hurry to the chase. Sir F. Head says that a Gaucho in the
Pampas, upon merely seeing some condors wheeling in the
air, cried " A lion ! " I could never myself meet with any one
who pretended to such powers of discrimination. It is as-
serted that, if a puma has once been betrayed by thus watch-
ing the carcass, and has then been hunted, it never resumes
this habit ; but that, having gorged itself, it wanders far away.
The puma is easily killed. In an open country, it is first
entangled with the bolas, then lazoed, and dragged along the
ground till rendered insensible. At Tandeel (south of the
Plata), I was told that within three months one hundred
were thus destroyed. In Chile they are generally driven up
bushes or trees, and are then either shot, or baited to death
by dogs. The dogs employed in this chase belong to a par-
ticular breed, called Leoneros : they are weak, slight animals,
like long-legged terriers, but are born with a particular
instinct for this sport. The puma is described as being very
crafty: when pursued, it often returns on its former track,
and then suddenly making a spring on one side, waits there
till the dogs have passed by. It is a very silent animal,
uttering no cry even when wounded, and only rarely during
the breeding season.

Of birds, two species of the genus Pteroptochos (mega-
podius and albicollis of Kittlitz) are perhaps the most con-
spicuous. The former, called by the Chilenos " el Turco,"
is as large as a fieldfare, to which bird it has some alliance;
but its legs are much longer, tail shorter, and beak stronger :
its colour is a reddish brown. The Turco is not uncommon.
It lives on the ground, sheltered among the thickets which are
scattered over the dry and sterile hills. With its tail erect,
and stilt-like legs, it may be seen every now and then pop-
ping from one bush to another with uncommon quickness.
It really requires little imagination to believe that the bird is
ashamed of itself, and is aware of its most ridiculous figure.
On first seeing it, one is tempted to exclaim, " A vilely stuffed
specimen has escaped from some museum, and has come to
life again ! " It cannot be made to take flight without the

288 CHARLES DARWIN

greatest trouble, nor does it run, but only hops. The various
loud cries which it utters when concealed amongst the bushes,
are as strange as its appearance. It is said to build its
nest in a deep hole beneath the ground. I dissected several
specimens : the gizzard, which was very muscular, contained
beetles, vegetable fibres, and pebbles. From this character,
from the length of its legs, scratching feet, membranous
covering to the nostrils, short and arched wings, this bird
seems in a certain degree to connect the thrushes with the
gallinaceous order.

The second species (or P. albicollis) is allied to the first
in its general form. It is called Tapacolo, or " cover your
posterior;" and well does the shameless little bird deserve its
name; for it carries its tail more than erect, that is, inclined
backwards towards its head. It is very common, and fre-
quents the bottoms of hedge-rows, and the bushes scattered
over the barren hills, where scarcely another bird can exist.
In its general manner of feeding, of quickly hopping out of
the thickets and back again, in its desire of concealment,
unwillingness to take flight, and nidification, it bears a close
resemblance to the Turco; but its appearance is not quite so
ridiculous. The Tapacolo is very crafty : when frightened by
any person, it will remain motionless at the bottom of a bush,
and will then, after a little while, try with much address to
crawl away on the opposite side. It is also an active bird, and
continually making a noise : these noises are various and
strangely odd ; some are like the cooing of doves, others like
the bubbling of water, and many defy all similes. The coun-
try people say it changes its cry five times in the year —
according to some change of season, I suppose.4

Two species of humming-birds are common; Trochilus
forficatus is found over a space of 2500 miles on the west
coast, from the hot dry country of Lima, to the forests of
Tierra del Fuego — where it may be seen flitting about in
snow-storms. In the wooded island of Chiloe, which has an

* It is a remarkable fact, that Molina, though describing in detail all the
birds and animals of Chile, never once mentions this genus, the species
of which are so common, and so remarkable in their habits. Was lie at
a loss how to classify them, and did he consequently think that silence
was the more prudent course? It is one more instance of the frequency
of omissions by authors, on those very subjects where it might have been
least expected.

THE VOYAGE OF THE BEAGLE 289

extremely humid climate, this little bird, skipping from side
to side amidst the dripping foliage, is perhaps more abundant
than almost any other kind. I opened the stomachs of several
specimens, shot in different parts of the continent, and in all,
remains of insects were as numerous as in the stomach of a
creeper. When this species migrates in the summer south-
ward, it is replaced by the arrival of another species coming
from the north. This second kind (Trochilus gigas) is a
very large bird for the delicate family to which it belongs:
when on the wing its appearance is singular. Like others
of the genus, it moves from place to place with a rapidity
which may be compared to that of Syrphus amongst flies,
and Sphinx among moths ; but whilst hovering over a flower,
it flaps its wings with a very slow and powerful movement,
totally different from that vibratory one common to most of
the species, which produces the humming noise. I never saw
any other bird where the force of its wings appeared (as in a
butterfly) so powerful in proportion to the weight of its body.
When hovering by a flower, its tail is constantly expanded
and shut like a fan, the body being kept in a nearly vertical
position. This action appears to steady and support the bird,
between the slow movements of its wings. Although flying
from flower to flower in search of food, its stomach generally
contained abundant remains of insects, which I suspect are
much more the object of its search than honey. The note of
this species, like that of nearly the whole family, is extremely
shrill.

71 TOVEMBER loth—The Beagle sailed from Valparaiso
l\ to the south, for the purpose of surveying the south-
ern part of Chile, the island of Chiloe, and the broken
land called the Chonos Archipelago, as far south as the
Peninsula of Tres Montes. On the 2ist we anchored in the
bay of S. Carlos, the capital of Chiloe.

This island is about ninety miles long, with a breadth of
rather less than thirty. The land is hilly, but not mountain-
ous, and is covered by one great forest, except where a few
green patches have been cleared round the thatched cottages.
From a distance the view somewhat resembles that of Tierra
del Fuego ; but the woods, when seen nearer, are incompara-
bly more beautiful. Many kinds of fine evergreen trees, and
plants with a tropical character, here take the place of the
gloomy beech of the southern shores. In winter the climate
is detestable, and in summer it is only a little better. I should
think there are few parts of the world, within the temperate
regions, where so much rain falls. The winds are very bois-
terous, and the sky almost always clouded : to have a week of
fine weather is something wonderful. It is even difficult to
get a single glimpse of the Cordillera : during our first visit,
once only the volcano of Osorno stood out in bold relief, and
that was before sunrise; it was curious to watch, as the sun
rose, the outline gradually fading away in the glare of the
eastern sky.

The inhabitants, from their complexion and low stature,

290

THE VOYAGE OF THE BEAGLE 291

appear to have three-fourths of Indian blood in their veins.
They are an humble, quiet, industrious set of men. Although
the fertile soil, resulting from the decomposition of the vol-
canic rocks, supports a rank vegetation, yet the climate is not
favourable to any production which requires much sunshine
to ripen it. There is very little pasture for the larger quad-
rupeds ; and in consequence, the staple articles of food are
pigs, potatoes, and fish. The people all dress in strong
woollen garments, which each family makes for itself, and
dyes with indigo of a dark blue colour. The arts, however,
are in the rudest state; — as may be seen in their strange
fashion of ploughing, their method of spinning, grinding
corn, and in the construction of their boats. The forests are
so impenetrable, that the land is nowhere cultivated except
near the coast and on the adjoining islets. Even where paths
exist, they are scarcely passable from the soft and swampy
state of the soil. The inhabitants, like those of Tierra del
Fuego, move about chiefly on the beach or in boats. Although
with plenty to eat, the people are very poor: there is no
demand for labour, and consequently the lower orders cannot
scrape together money sufficient to purchase even the smallest
luxuries. There is also a great deficiency of a circulating
medium. I have seen a man bringing on his back a bag of
charcoal, with which to buy some trifle, and another carrying
a plank to exchange for a bottle of wine. Hence every trades-
man must also be a merchant, and again sell the goods which
he takes in exchange.

November 24th. — The yawl and whale-boat were sent under
the command of Mr. (now Captain) Sulivan, to survey the
eastern or inland coast of Chiloe ; and with orders to meet
the Beagle at the southern extremity of the island ; to which
point she would proceed by the outside, so as thus to cir-
cumnavigate the whole. I accompanied this expedition, but
instead of going in the boats the first day, I hired horses to
take me to Chacao, at the northern extremity of the island.
The road followed the coast; every now and then crossing
promontories covered by fine forests. In these shaded paths
it is absolutely necessary that the whole road should be made
of logs of wood, which are squared and placed by the side of
each other. From the rays of the sun never penetrating the

292 CHARLES DARWIN

evergreen foliage, the ground is so damp and soft, that except
by this means neither man nor horse would be able to pass
along. I arrived at the village of Chacao shortly after the
tents belonging to the boats were pitched for the night.

The land in this neighbourhood has been extensively
cleared, and there were many quiet and most picturesque
nooks in the forest. Chacao was formerly the principal port
in the island ; but many vessels having been lost, owing to the
dangerous currents and rocks in the straits, the Spanish gov-
ernment burnt the church, and thus arbitrarily compelled the
greater number of inhabitants to migrate to S. Carlos. We
had not long bivouacked, before the barefooted son of the
governor came down to reconnoitre us. Seeing the English
flag hoisted at the yawl's mast-head, he asked with the utmost
indifference, whether it was always to fly at Chacao. In sev-
eral places the inhabitants were much astonished at the
appearance of men-of-war's boats, and hoped and believed
it was the forerunner of a Spanish fleet, coming to recover
the island from the patriot government of Chile. All the
men in power, however, had been informed of our intended
visit, and were exceedingly civil. While we were eating our
supper, the governor paid us a visit. He had been a lieuten-
ant-colonel in the Spanish service, but now was miserably
poor. He gave us two sheep, and accepted in return two cot-
ton handkerchiefs, some brass trinkets, and a little tobacco.

2$th. — Torrents of rain: we managed, however, to run
down the coast as far as Huapi-lenou. The whole of this
eastern side of Chiloe has one aspect ; it is a plain, broken by
valleys and divided into little islands, and the whole thickly
covered with one impervious blackish-green forest. On the
margins there are some cleared spaces, surrounding the high-
roofed cottages.

26th. — The day rose splendidly clear. The volcano of
Orsono was spouting out volumes of smoke. This most
beautiful mountain, formed like a perfect cone, and white
with snow, stands out in front of the Cordillera. Another
great volcano, with a saddle-shaped summit, also emitted
from its immense crater little jets of steam. Subsequently
we saw the lofty-peaked Corcovado — well deserving the name
of " el famoso Corcovado." Thus we beheld, from one point

THE VOYAGE OF THE BEAGLE 293

of view, three great active volcanoes, each about seven thou-
sand feet high. In addition to this, far to the south, there
were other lofty cones covered with snow, which, although
not known to be active, must be in their origin volcanic.
The line of the Andes is not, in this neighbourhood, nearly
so elevated as in Chile; neither does it appear to form so
perfect a barrier between the regions of the earth. This
great range, although running in a straight north and south
line, owing to an optical deception, always appeared more or
less curved; for the lines drawn from each peak to the
beholder's eye, necessarily converged like the radii of a
semicircle, and as it was not possible (owing to the clearness
of the atmosphere and the absence of all intermediate, ob-
jects) to judge how far distant the farthest peaks were off,
they appeared to stand in a flattish semicircle.

Landing at midday, we saw a family of pure Indian extrac-
tion. The father was singularly like York Minster ; and some
of the younger boys, with their ruddy complexions, might
have been mistaken for Pampas Indians. Everything I have
seen, convinces me of the close connexion of the different
American tribes, who nevertheless speak distinct languages.
This party could muster but little Spanish, and talked to each
other in their own tongue. It is a pleasant thing to see the
aborigines advanced to the same degree of civilization, how-
ever low that may be, which their white conquerors have
attained. More to the south we saw many pure Indians:
indeed, all the inhabitants of some of the islets retain their
Indian surnames. In the census of 1832, there were in Chiloe
and its dependencies forty-two thousand souls; the greater
number of these appear to be of mixed blood. Eleven thou-
sand retain their Indian surnames, but it is probable that not
nearly all of these are of a pure breed. Their manner of life
is the same with that of the other poor inhabitants, and they
are all Christians; but it is said that they yet retain some
strange superstitious ceremonies, and that they pretend to
hold communication with the devil in certain caves. For-
merly, every one convicted of this offence was sent to the
Inquisition at Lima. Many of the inhabitants who are not
included in the eleven thousand with Indian surnames, can-
not be distinguished by their appearance from Indians.

294 CHARLES DARWIN

Gomez, the governor of Lemuy, is descended from noblemen
of Spain on both sides ; but by constant intermarriages with
the natives the present man is an Indian. On the other hand,
the governor of Quinchao boasts much of his purely kept
Spanish blood.

We reached at night a beautiful little cove, north of the
island of Caucahue. The people here complained of want of
land. This is partly owing to their own negligence in not
clearing the woods, and partly to restrictions by the govern-
ment, which makes it necessary, before buying ever so small
a piece, to pay two shillings to the surveyor for measuring
each quadra (150 yards square), together with whatever
price he fixes for the value of the land. After his valuation,
the land must be put up three times to auction, and if no one
bids more, the purchaser can have it at that rate. All these
exactions must be a serious check to clearing the ground,
where the inhabitants are so extremely poor. In most coun-
tries, forests are removed without much difficulty by the aid
of fire; but in Chiloe, from the damp nature of the climate,
and the sort of trees, it is necessary first to cut them down.
This is a heavy drawback to the prosperity of Chiloe. In the
time of the Spaniards the Indians could not hold land; and a
family, after having cleared a piece of ground, might be
driven away, and the property seized by the government.
The Chilian authorities are now performing an act of justice
by making retribution to these poor Indians, giving to each
man, according to his grade of life, a certain portion of land.
The value of uncleared ground is very little. The govern-
ment gave Mr. Douglas (the present surveyor, who informed
me of these circumstances) eight and a half square miles of
forest near S. Carlos, in lieu of a debt; and this he sold for
350 dollars, or about 7o/. sterling.

The two succeeding days were fine, and at night we reached
the island of Quinchao. This neighbourhood is the most cul-
tivated part of the Archipelago; for a broad strip of land on
the coast of the main island, as well as on many of the smallei
adjoining ones, is almost completely cleared. Some of the
farmhouses seemed very comfortable. I was curious to
ascertain how rich any of these people might be, but Mr.
Douglas says that no one can be considered as possessing a

THE VOYAGE OF THE BEAGLE 295

regular income. One of the richest land-owners might pos-
sibly accumulate, in a long industrious life, as much as iooo/.
sterling; but should this happen, it would all be stowed away
in some secret corner, for it is the custom of almost every
family to have a jar or treasure-chest buried in the ground.

November joth. — Early on Sunday morning we reached
Castro, the ancient capital of Chiloe, but now a most forlorn
and deserted place. The usual quadrangular arrangement
of Spanish towns could be traced, but the streets and plaza
were coated with fine green turf, on which sheep were
browsing. The church, which stands in the middle, is entirely
built of plank, and has a picturesque and venerable appear-
ance. The poverty of the place may be conceived from the
fact, that although containing some hundreds of inhabitants,
one of our party was unable anywhere to purchase either a
pound of sugar or an ordinary knife. No individual possessed
either a watch or a clock ; and an old man, who was supposed
to have a good idea of time, was employed to strike the
church bell by guess. The arrival of our boats was a rare
event in this quiet retired corner of the world ; and nearly all
the inhabitants came down to the beach to see us pitch our
tents. They were very civil, and offered us a house ; and one
man even sent us a cask of cider as a present. In the after-
noon we paid our respects to the governor — a quiet old man,
who, in his appearance and manner of life, was scarcely
superior to an English cottager. At night heavy rain set in,
which was hardly sufficient to drive away from our tents the
large circle of lookers-on. An Indian family, who had come
to trade in a canoe from Caylen, bivouacked near us. They
had no shelter during the rain. In the morning I asked a
young Indian, who was wet to the skin, how he had passed
the night. He seemed perfectly content, and answered, " Muy
bien, senor."

December ist. — We steered for the island of Lemuy. I
was anxious to examine a reported coal-mine which turned
out to be lignite of little value, in the sandstone (probably
of an ancient tertiary epoch) of which these islands are com-
posed. When we reached Lemuy we had much difficulty in
finding any place to pitch our tents, for it was spring-tide,
and the land was wooded down to the water's edge. In a

296 CHARLES DARWIN

short time we were surrounded by a large group of the nearly
pure Indian inhabitants. They were much surprised at our
arrival, and said one to the other, " This is the reason we
have seen so many parrots lately; the cheucau (an odd red-
breasted little bird, which inhabits the thick forest, and utters
very peculiar noises) has not cried ' beware ' for nothing."
They were soon anxious for barter. Money was scarcely
worth anything, but their eagerness for tobacco was some-
thing quite extraordinary. After tobacco, indigo came next
in value; then capsicum, old clothes, and gunpowder. The
latter article was required for a very innocent purpose : each
parish has a public musket, and the gunpowder was wanted
for making a noise on their saint or feast days.

The people here live chiefly on shell-fish and potatoes. At
certain seasons they catch also, in " corrales," or hedges
under water, many fish which are left on the mud-banks as
the tide falls. They occasionally possess fowls, sheep, goats,
pigs, horses, and cattle ; the order in which they are here
mentioned, expressing their respective numbers. I never
saw anything more obliging and humble than the manners
of these people. They generally began with stating that
they were poor natives of the place, and not Spaniards,
and that they were in sad want of tobacco and other com-
forts. At Caylen, the most southern island, the sailors
bought with a stick of tobacco, of the value of three-half-
pence, two fowls, one of which, the Indian stated, had skin
between its toes, and turned out to be a fine duck; and with
some cotton handkerchiefs, worth three shillings, three sheep
and a large bunch of onions were procured. The yawl at
this place was anchored some way from the shore, and we
had fears for her safety from robbers during the night. Our
pilot, Mr. Douglas, accordingly told the constable of the
district that we always placed sentinels with loaded arms,
and not understanding Spanish, if we saw any person in the
dark, we should assuredly shoot him. The constable, with
much humility, agreed to the perfect propriety of this
arrangement, and promised us that no one should stir out
of his house during that night.

During the four succeeding days we continued sailing
southward. The general features of the country remained

THE VOYAGE OF THE BEAGLE 297

the same, but it was much less thickly inhabited. On the
large island of Tanqui there was scarcely one cleared spot,
the trees on every side extending their branches over the
sea-beach. I one day noticed, growing on the sandstone
cliffs, some very fine plants of the panke (Gunnera scabra),
which somewhat resembles the rhubarb on a gigantic scale.
The inhabitants eat the stalks, which are subacid, and tan
leather with the roots, and prepare a black dye from them.
The leaf is nearly circular, but deeply indented on its mar-
gin. I measured one which was nearly eight feet in diame-
ter, and therefore no less than twenty-four in circumfer-
ence ! The stalk is rather more than a yard high, and each
plant sends out four or five of these enormous leaves, pre-
senting together a very noble appearance.

December 6th. — We reached Caylen, called " el fin del
Cristiandad." In the morning we stopped for a few minutes
at a house on the northern end of Laylec, which was the
extreme point of South American Christendom, and a mis-
erable hovel it was. The latitude is 43° 10', which is two
degrees farther south than the Rio Negro on the Atlantic
coast. These extreme Christians were very poor, and, under
the plea of their situation, begged for some tobacco. As a
proof of the poverty of these Indians, I may mention that
shortly before this, we had met a man, who had travelled
three days and a half on foot, and had as many to return,
for the sake of recovering the value of a small axe and a few
fish. How very difficult it must be to buy the smallest article,
when such trouble is taken to recover so small a debt.

In the evening we reached the island of San Pedro, where
we found the Beagle at anchor. In doubling the point, two
of the officers landed to take a round of angles with the
theodolite. A fox (Canis fulvipes), of a kind said to be
peculiar to the island, and very rare in it, and which is a new
species, was sitting on the rocks. He was so intently ab-
sorbed in watching the work of the officers, that I was able,
by quietly walking up behind, to knock him on the head
with my geological hammer. This fox, more curious or
more scientific, but less wise, than the generality of his
brethren, is now mounted in the museum of the Zoological
Society.

298 CHARLES DARWIN

We stayed three days in this harbour, on one of which
Captain Fitz Roy, with a party, attempted to ascend to the
summit of San Pedro. The woods here had rather a differ-
ent appearance from those on the northern part of the island.
The rock, also, being micaceous slate, there was no beach,
but the steep sides dipped directly beneath the water. The
general aspect in consequence was more like that of Tierra
del Fuego than of Chiloe. In vain we tried to gain the
summit: the forest was so impenetrable, that no one who
has not beheld it can imagine so entangled a mass of dying
and dead trunks. I am sure that often, for more than ten
minutes together, our feet never touched the ground, and
we were frequently ten or fifteen feet above it, so that the
seamen as a joke called out the soundings. At other times
we crept one after another on our hands and knees, under
the rotten trunks. In the lower part of the mountain, noble
trees of the Winter's Bark, and a laurel like the sassafras
with fragrant leaves, and others, the names of which I do
not know, were matted together by a trailing bamboo or cane.
Here we were more like fishes struggling in a net than any
other animal. On the higher parts, brushwood takes the
place of larger trees, with here and there a red cedar or an
alerce pine. I was also pleased to see, at an elevation of a
little less than 1000 feet, our old friend the southern beech.
They were, however, poor stunted trees; and I should think
that this must be nearly their northern limit. We ultimately
gave up the attempt in despair.

December loth. — The yawl and whale-boat, with Mr.
Sulivan, proceeded on their survey, but I remained on board
the Beagle, which the next day left San Pedro for the south-
ward. On the I3th we ran into an opening in the southern
part of Guayatecas, or the Chonos Archipelago; and it was
fortunate we did so, for on the following day a storm, worthy
of Tierra del Fuego, raged with great fury. White massive
clouds were piled up against a dark blue sky, and across them
black ragged sheets of vapour were rapidly driven. The suc-
cessive mountain ranges appeared like dim shadows; and
the setting sun cast on the woodland a yellow gleam, much
like that produced by the flame of spirits of wine. The water
was white with the flying spray, and the wind lulled and

THE VOYAGE OF THE BEAGLE 299

roared again through the rigging: it was an ominous, sub-
lime scene. During a few minutes there was a bright rain-
bow, and it was curious to observe the effect of the spray,
which being carried along the surface of the water, changed
the ordinary semicircle into a circle — a band of prismatic
colours being continued, from both feet of the common arch
across the bay, close to the vessel's side : thus forming a dis-
torted, but very nearly entire ring.

We stayed here three days. The weather continued bad:
but this did not much signify, for the surface of the land
in all these islands is all but impassable. The coast is so
very rugged that to attempt to walk in that direction re-
quires continued scrambling up and down over the sharp
rocks of mica-slate ; and as for the woods, our faces, hands,
and shin-bones all bore witness to the maltreatment we
received, in merely attempting to penetrate their forbidden
recesses.

December i8th. — We stood out to sea. On the 2oth we
bade farewell to the south, and with a fair wind turned the
ship's head northward. From Cape Tres Montes we sailed
pleasantly along the lofty weather-beaten coast, which is
remarkable for the bold outline of its hills, and the thick
covering of forest even on the almost precipitous flanks. The
next day a harbour was discovered, which on this dangerous
coast might be of great service to a distressed vessel. It
can easily be recognized by a hill 1600 feet high, which is
even more perfectly conical than the famous sugar-loaf at
Rio de Janeiro. The next day, after anchoring, I succeeded
in reaching the summit of this hill. It was a laborious under-
taking, for the sides were so steep that in some parts it was
necessary to use the trees as ladders. There were also several
extensive brakes of the Fuchsia, covered with its beautiful
drooping flowers, but very difficult to crawl through. In
these wild countries it gives much delight to gain the summit
of any mountain. There is an indefinite expectation of seeing
something very strange, which, however often it may be
balked, never failed with me to recur on each successive
attempt. Every one must know the feeling of triumph and
pride which a grand view from a height communicates to the
mind. In these little frequented countries there is also joined

300 CHARLES DARWIN

to it some vanity, that you perhaps are the first man who ever
stood on this pinnacle or admired this view.

A strong desire is always felt to ascertain whether any
human being has previously visited an unfrequented spot.
A bit of wood with a nail in it, is picked up and studied as
if it were covered with hieroglyphics. Possessed with this
feeling, I was much interested by finding, on a wild part of
the coast, a bed made of grass beneath a ledge of rock. Close
by it there had been a fire, and the man had used an axe.
The fire, bed, and situation showed the dexterity of an Indian ;
but he could scarcely have been an Indian, for the race is
in this part extinct, owing to the Catholic desire of making
at one blow Christians and Slaves. I had at the time some
misgivings that the solitary man who had made his bed on
this wild spot, must have been some poor shipwrecked sailor,
who, in trying to travel up the coast, had here laid himself
down for his dreary night.

December 28th. — The weather continued very bad, but it
at last permitted us to proceed with the survey. The time
hung heavy on our hands, as it always did when we were
delayed from day to day by successive gales of wind. In
the evening another harbour was discovered, where we
anchored. Directly afterwards a man was seen waving a
shirt, and a boat was sent which brought back two seamen.
A party of six had run away from an American whaling
vessel, and had landed a little to the southward in a boat,
which was shortly afterwards knocked to pieces by the surf.
They had now been wandering up and down the coast for
fifteen months, without knowing which way to go, or where
they were. What a singular piece of good fortune it was
that this harbour was now discovered ! Had it not been for
this one chance, they might have wandered till they had
grown old men, and at last have perished on this wild coast.
Their sufferings had been very great, and one of their party
had lost his life by falling from the cliffs. They were some-
times obliged to separate in search of food, and this explained
the bed of the solitary man. Considering what they had
undergone, I think they had kept a very good reckoning of
time, for they had lost only four days.

December joth. — We anchored in a snug little cove at the

THE VOYAGE OF THE BEAGLE 301

foot of some high hills, near the northern extremity of Tres
Monies. After breakfast the next morning, a party ascended
one of these mountains, which was 2400 feet high. The
scenery was remarkable. The chief part of the range was
composed of grand, solid, abrupt masses of granite, which
appeared as if they had been coeval with the beginning of
the world. The granite was capped with mica-slate, and this
in the lapse of ages had been worn into strange finger-
shaped points. These two formations, thus differing in their
outlines, agree in being almost destitute of vegetation. This
barrenness had to our eyes a strange appearance, from having
been so long accustomed to the sight of an almost universal
forest of dark-green trees. I took much delight in examining
the structure of these mountains. The complicated and lofty
ranges bore a noble aspect of durability — equally profitless,
however, to man and to all other animals. Granite to the
geologist is classic ground : from its widespread limits, and its
beautiful and compact texture, few rocks have been more
anciently recognised. Granite has given rise, perhaps, to
more discussion concerning its origin than any other forma-
tion. We generally see it constituting the fundamental rock,
and, however formed, we know it is the deepest layer in the
crust of this globe to which man has penetrated. The limit
of man's knowledge in any subject possesses a high interest,
which is perhaps increased by its close neighbourhood to the
realms of imagination.

January ist, 1835. — The new year is ushered in with the
ceremonies proper to it in these regions. She lays out no
false hopes: a heavy north-western gale, with steady rain,
bespeaks the rising year. Thank God, we are not destined
Here to see the end of it, but hope then to be in the Pacific
Ocean, where a blue sky tells one there is a heaven, — a some-
thing beyond the clouds above our heads.

The north-west winds prevailing for the next four days,
we only managed to cross a great bay, and then anchored in
another secure harbour. I accompanied the Captain in a
boat to the head of a deep creek. On the way the number of
seals which we saw was quite astonishing: every bit of flat
rock, and parts of the beach, were covered with them. They
appeared to be of a loving disposition, and lay huddled to-

302 CHARLES DARWIN"

gether, fast asleep, like so many pigs; but even pigs would
have been ashamed of their dirt, and of the foul smell which
came from them. Each herd was watched by the patient but
inauspicious eyes of the turkey-buzzard. This disgusting bird,
with its bald scarlet head, formed to wallow in putridity, is
very common on the west coast, and their attendance on the
seals shows on what they rely for their food. We found the
water (probably only that of the surface) nearly fresh: this
was caused by the number of torrents which, in the form
of cascades, came tumbling over the bold granite mountains
into the sea. The fresh water attracts the fish, and these
bring many terns, gulls, and two kinds of cormorant. We
saw also a pair of the beautiful black-necked swans, and
several small sea-otters, the fur of which is held in such
high estimation. In returning, we were again amused by the
impetuous manner in which the heap of seals, old and young,
tumbled into the water as the boat passed. They did not
remain long under water, but rising, followed us with out-
stretched necks, expressing great wonder and curiosity.

?th. — Having run up the coast, we anchored near the
northern end of the Chonos Archipelago, in Low's Harbour,
where we remained a week. The islands were here- as in
Chiloe, composed of a stratified, soft, littoral deposit; and
the vegetation in consequence was beautifully luxuriant. The
woods came down to the sea-beach, just in the manner of
an evergreen shrubbery over a gravel walk. We also enjoyed
from the anchorage a splendid view of four great snowy
cones of the Cordillera, including " el f amoso Corcovado ; "
the range itself had in this latitude so little height, that few
parts of it appeared above the tops of the neighbouring
islets. We found here a party of five men from Caylen, " el
fin del Cristiandad," who had most adventurously crossed in
their miserable boat-canoe, for the purpose of fishing, the
open space of sea which separates Chonos from Chiloe. These
islands will, in all probability, in a short time become peopled
like those adjoining the coast of Chiloe.

The wild potato grows on these islands in great abundance,
on the sandy, shelly soil near the sea-beach. The tallest
plant was four feet in height. The tubers were generally

THE VOYAGE OF THE BEAGLE 303

rmall, but I found one, of an oval shape, two inches in
diameter : they resembled in every respect, and had the same
smell as English potatoes ; but when boiled they shrunk much,
and were watery and insipid, without any bitter taste. They
are undoubtedly here indigenous : they grow as far south,
according to Mr. Low, as lat. 50°, and are called Aquinas by
the wild Indians of that part: the Chilotan Indians have a
different name for them. Professor Henslow, who has ex-
amined the dried specimens which I brought home, says that
they are the same with those described by Mr. Sabine 1 from
Valparaiso, but that they form a variety which by some
botanists has been considered as specifically distinct. It is
remarkable that the same plant should be found on the sterile
mountains of central Chile, where a drop of rain does not
fall for more than six months, and within the damp forests
of these southern islands.

In the central parts of the Chonos Archipelago (lat. 45°),
the forest has very much the same character with that along
the whole west coast, for 600 miles southward to Cape Horn.
The arborescent grass of Chiloe is not found here ; while the
beech of Tierra del Fuego grows to a good size, and forms a
considerable proportion of the wood; not, however, in the
same exclusive manner as it does farther southward. Crypto-
gamic plants here find a most congenial climate. In the Strait
of Magellan, as I have before remarked, the country appears
too cold and wet to allow of their arriving at perfection ; but
in these islands, within the forest, the number of species and
great abundance of mosses, lichens, and small ferns, is quite
extraordinary.* In Tierra del Fuego trees grow only on the
hillsides; every level piece of land being invariably covered
by a thick bed of peat; but in Chiloe flat land supports the
most luxuriant forests. Here, within the Chonos Archipel-
ago, the nature of the climate more closely approaches that

1 Horticultural Transact., vol. v. p. 249. Mr. Caldcleugh sent home
two tubers, which, being well manured, even the first season produced
numerous potatoes and an abundance of leaves. See Humboldt's interest-
ing discussion on this plant, which it appears was unknown in Mexico, —
in Polit. Essay on New Spain, book iv. chap. ix.

* By sweeping with my insect-net, I procured from these situations a
considerable number of minute insects, of the family of Staphylinidae, and
others allied to Pselaphus, and minute Hymenoptera. But _the most char-
acteristic family in number, both of individuals and species, throughout
the more open parts of Chiloe and Chonos is that of the Telephone!*.

304 CHARLES DARWIN

of Tierra del Fuego than that of northern Chiloe; for every
patch of level ground is covered by two species of plants
(Astelia pumila and Donatia magellanica), which by their
joint decay compose a thick bed of elastic peat.

In Tierra del Fuego, above the region of woodland, the
former of these eminently sociable plants is the chief agent
in the production of peat. Fresh leaves are always succeed-
ing one to the other round the central tap-root; the lower
ones soon decay, and in tracing a root downwards in the peat,
the leaves, yet holding their place, can be observed passing
through every stage of decomposition, till the whole becomes
blended in one confused mass. The Astelia is assisted by a
few other plants, — here and there a small creeping Myrtus
(M. nummularia), with a woody stem like our cranberry and
with a sweet berry, — an Empetrum (E. rubrum), like our
heath, — a rush (Juncus grandiflorus), are nearly the only
ones that grow on the swampy surface. These plants, though
possessing a very close general resemblance to the English
species of the same genera, are different. In the more level
parts of the country, the surface of the peat is broken up into
little pools of water, which stand at different heights, and
appear as if artificially excavated. Small streams of water,
flowing underground, complete the disorganization of the
vegetable matter, and consolidate the whole.

The climate of the southern part of America appears partic-
ularly favourable to the production of peat. In the Falkland
Islands almost every kind of plant, even the coarse grass
which covers the whole surface of the land, becomes con-
verted into this substance: scarcely any situation checks its
growth; some of the beds are as much as twelve feet thick,
and the lower part becomes so solid when dry, that it will
hardly burn. Although every plant lends its aid, yet in most
parts the Astelia is the most efficient. It is rather a singular
circumstance, as being so very different from what occurs
in Europe, that I nowhere saw moss forming by its decay
any portion of the peat in South America. With respect to
the northern limit, at which the climate allows of that pecul-
iar kind of slow decomposition which is necessary for its
production, I believe that in Chiloe (lat. 41° to 42°), although
there is much swampy ground, no well-characterized peat

THE VOYAGE OF THE BEAGLE 305

occurs: but in the Chonos Islands, three degrees farther
southward, we have seen that it is abundant. On the eastern
coast in La Plata (lat. 35°) I was told by a Spanish resident
who had visited Ireland, that he had often sought for this
substance, but had never been able to find any. He showed
me, as the nearest approach to it which he had discovered, a
black peaty soil, so penetrated with roots as to allow of an
extremely slow and imperfect combustion.

The zoology of these broken islets of the Chonos Archi-
pelago is, as might have been expected, very poor. Of quad-
rupeds two aquatic kinds are common. The Myopotamus
Coypus (like a beaver, but with a round tail) is well known
from its fine fur, which is an object of trade throughout the
tributaries of La Plata. It here, however, exclusively fre-
quents salt water; which same circumstance has been men-
tioned as sometimes occurring with the great rodent, the
Capybara. A small sea-otter is very numerous; this animal
does not feed exclusively on fish, but, like the seals, draws a
large supply from a small red crab, which swims in shoals
near the surface of the water. Mr. Bynoe saw one in Tierra
del Fuego eating a cuttle-fish ; and at Low's Harbour, another
was killed in the act of carrying to its hole a large volute
shell. At one place I caught in a trap a singular little mouse
(M. brachiotis) ; it appeared common on several of the islets,
but the Chilotans at Low's Harbour said that it was not found
in all. What a succession of chances,* or what changes of
level must have been brought into play, thus to spread these
small animals throughout this broken archipelago !

In all parts of Chiloe and Chonos, two very strange birds
occur, which are allied to, and replace, the Turco and Tapa-
colo of central Chile. One is called by the inhabitants
"Cheucau" (Pteroptochos rubecula) : it frequents the most
gloomy and retired spots within the damp forests. Some-
times, although its cry may be heard close at hand, let a per-
son watch ever so attentively he will not see the cheucau ; at

* It is said that some rapacious birds bring their prey alive to their
nests. If so, in the course of centuries, every now and then, one might
.escape from the young birds. Some such agency is necessary, to account
for the distribution of the smaller gnawing animals on islands not very
near each other.

306 CHARLES DARWIN

other times, let him stand motionless and the red-breasted
little bird will approach within a few feet in the most familiar
manner. It then busily hops about the entangled mass of
rotting canes and branches, with its little tail cocked upwards.
The cheucau is held in superstitious fear by the Chilotans, on
account of its strange and varied cries. There are three
very distinct cries : one is called " chiduco," and is an omen
of good ; another, " huitreu," which is extremely unfavour-
able; and a third, which I have forgotten. These words are
given in imitation of the noises ; and the natives are in some
things absolutely governed by them. The Chilotans assuredly
have chosen a most comical little creature for their prophet.
An allied species, but rather larger, is called by the natives
" Guid-guid" (Pteroptochos Tarnii), and by the English the
barking-bird. This latter name is well given ; for I defy any
one at first to feel certain that a small dog is not yelping
somewhere in the forest. Just as with the cheucau, a person
will sometimes hear the bark close by, but in vain many
endeavour by watching, and with still less chance by beating
the bushes, to see the bird; yet at other times the guid-guid
fearlessly comes near. Its manner of feeding and its general
habits are very similar to those of the cheucau.

On the coast* a small dusky-coloured bird (Opetiorhyn-
chus Patagonicus) is very common. It is remarkable from
its quiet habits; it lives entirely on the sea-beach, like a
sandpiper. Besides these birds only few others inhabit this
broken land. In my rough notes I describe the strange
noises, which, although frequently heard within these gloomy
forests, yet scarcely disturb the general silence. The yelp-
ing of the guid-guid, and the sudden whew-whew of the
cheucau, sometimes come from afar off, and sometimes from
close at hand ; the little black wren of Tierra del Fuego oc-
casionally adds its cry; the creeper (Oxyurus) follows the
intruder screaming and twittering; the humming-bird may
be seen every now and then darting from side to side, and
emitting, like an insect, its shrill chirp; lastly, from the top

4 I may mention, as a proof of how great a difference there is between the
seasons of the wooded and the open parts of this coast, that on September
20th, in lat. 34°, these birds had young ones in the nest, while among _the
Chonos Islands, three months later in the summer, they were only laying,
the difference in latitude between these two places being about 700 miles.

THE VOYAGE OF THE BEAGLE 307

of some lofty tree the indistinct but plaintive note of the
white-tufted tyrant-flycatcher (Myiobius) may be noticed.
From the great preponderance in most countries of certain
common genera of birds, such as the finches, one feels at
first surprised at meeting with the peculiar forms above enu-
merated, as the commonest birds in any district. In central
Chile two of them, namely, the Oxyurus and Scytalopus, oc-
cur, although most rarely. When finding, as in this case,
animals which seem to play so insignificant a part in the great
scheme of nature, one is apt to wonder why they were
created.

But it should always be recollected, that in some other
country perhaps they are essential members of society, or
at some former period may have been so. If America
south of 37° were sunk beneath the waters of the ocean,
these two birds might continue to exist in central Chile for
a long period, but it is very improbable that their numbers
would increase. We should then see a case which must in-
evitably have happened with very many animals.

These southern seas are frequented by several species of
Petrels: the largest kind, Procellaria gigantea, or nelly (que-
brantahuesos, or break-bones, of the Spaniards), is a com-
mon bird, both in the inland channels and on the open sea.
In its habits and manner of flight, there is a very close re-
semblance with the albatross; and as with the albatross, a
person may watch it for hours together without seeing on
what it feeds. The " break-bones " is, however, a rapacious
bird, for it was observed by some of the officers at Port St.
Antonio chasing a diver, which tried to escape by diving
and flying, but was concinually struck down, and at last
killed by a blow on its head. At Port St. Julian these great
petrels were seen killing and devouring young gulls. A sec-
ond species (Puffinus cinereus), which is common to Europe,
Cape Horn, and the coast of Peru, is of much smaller size
than the P. gigantea, but, like it, of a dirty black colour. It
generally frequents the inland sounds in very large flocks :
I do not think I ever saw so many birds of any other sort
together, as I once saw of these behind the island of Chiloe.
Hundreds of thousands flew in an irregular line for several
I hours in one direction. When part of the flock settled on the

308 CHARLES DARWIN

water the surface was blackened, and a noise proceeded from
them as of human beings talking in the distance.

There are several other species of petrels, but I will only
mention one other kind, the Pelacanoides Berardi, which
offers an example of those extraordinary cases, of a bird
evidently belonging to one well-marked family, yet both in
its habits and structure allied to a very distinct tribe. This
bird never leaves the quiet inland sounds. When disturbed
it dives to a distance, and on coming to the surface, with the
same movement takes flight. After flying by a rapid move-
ment of its short wings for a space in a straight line, it drops,
as if struck dead, and dives again. The form of its beak and
nostrils, length of foot, and even the colouring of its plum-
age, show that this bird is a petrel: on the other hand, its
short wings and consequent little power of flight, its form
of body and shape of tail, the absence of a hind toe to its
foot, its habit of diving, and its choice of situation, make it
at first doubtful whether its relationship is not equally close
with the auks. It would undoubtedly be mistaken for an auk,
when seen from a distance, either on the wing, or when div-
ing and quietly swimming about the retired channels of
Tierra del Fuego.

CHAPTER XIV
CHILOE AND CONCEPCION : GREAT EARTHQUAKE

ON JANUARY the 15th we sailed from Low's Harbour,
and three days afterwards anchored a second time in
the bay of S. Carlos in Chiloe. On the night of the
igth the volcano of Osorno was in action. At midnight the
sentry observed something like a large star, which gradually
increased in size till about three o'clock, when it presented
a very magnificent spectacle. By the aid of a glass, dark
objects, in constant succession, were seen, in the midst of a
great glare of red light, to be thrown up and to fall down.
The light was sufficient to cast on the water a long bright
reflection. Large masses of molten matter seem very com-
monly to be cast out of the craters in this part of the Cordil-
lera. I was assured that when the Corcovado is in eruption,
great masses are projected upwards and are seen to burst in
the air, assuming many fantastical forms, such as trees:
their size must be immense, for they can be distinguished
from the high land behind S. Carlos, which is no less than
ninety-three miles from the Corcovado. In the morning the
volcano became tranquil.

I was surprised at hearing afterwards that Aconcagua in
Chile, 480 miles northwards, was in action on the same night ;
and still more surprised to hear that the great eruption of
Coseguina (2700 miles north of Aconcagua), accompanied by
an earthquake felt over a 1000 miles, also occurred within

309

310 CHARLES DARWIN

six hours of this same time. This coincidence is the more
remarkable, as Coseguina had been dormant for twenty-six
years ; and Aconcagua most rarely shows any signs of action.
It is difficult even to conjecture whether this coincidence was
accidental, or shows some subterranean connection. If Vesu-
vius, Etna, and Hecla in Iceland (all three relatively nearer
each other than the corresponding points in South America),
suddenly burst forth in eruption on the same night, the coin-
cidence would be thought remarkable; but it is far more re-
markable in this case, where the three vents fall on the same
great mountain-chain, and where the vast plains along the
entire eastern coast, and the upraised recent shells along
more than 2000 miles on the western coast, show in how
equable and connected a manner the elevatory forces have
acted.

Captain Fitz Roy being anxious that some bearings should
be taken on the outer coast of Chiloe, it was planned that
Mr. King and myself should ride to Castro, and thence across
the island to the Capella de Cucao, situated on the west
coast. Having hired horses and a guide, we set out on
the morning of the 22nd. We had not proceeded far, before
we were joined by a woman and two boys, who were bent on
the same journey. Every one on this road acts on a " hail
fellow well met " fashion; and one may here enjoy the privi-
lege, so rare in South America, of travelling without fire-
arms. At first, the country consisted of a succession of hills
and valleys : nearer to Castro it became very level. The road
itself is a curious affair; it consists in its whole length, with
the exception of very few parts, of great logs of wood, which
are either broad and laid longitudinally, or narrow and placed
transversely. In summer the road is not very bad; but in
winter, when the wood is rendered slippery from rain, trav-
elling is exceedingly difficult. At that time of the year, the
ground on each side becomes a morass, and is often over-
flowed: hence it is necessary that the longitudinal logs
should be fastened down by tranverse poles, which are
pegged on each side into the earth. These pegs render a fall
from a horse dangerous, as the chance of alighting on one of
them is not small. It is remarkable, however, how active
custom has made the Chilotan horses. In crossing bad parts,

THE VOYAGE OF THE BEAGLE 311

where the logs had been displaced, they skipped from one
to the other, almost with the quickness and certainty of a
dog. On both hands the road is bordered by the lofty forest-
trees, with their bases matted together by canes. When oc-
casionally a long reach of this avenue could be beheld, it pre-
sented a curious scene of uniformity: the white line of logs,
narrowing in perspective, became hidden by the gloomy forest,
or terminated in a zigzag which ascended some steep hill.

Although the distance from S. Carlos to Castro is only
twelve leagues in a straight line, the formation of the road
must have been a great labour. I was told that several peo-
ple had formerly lost their lives in attempting to cross the
forest. The first who succeeded was an Indian, who cut his
way through the canes in eight days, and reached S. Carlos :
he was rewarded by the Spanish government with a grant of
land. During the summer, many of the Indians wander
about the forests (but chiefly in the higher parts, where the
woods are not quite so thick) in search of the half-wild cattle
which live on the leaves of the cane and certain trees. It
was one of these huntsmen who by chance discovered, a few
years since, an English vessel, which had been wrecked on the
outer coast. The crew were beginning to fail in provisions,
and it is not probable that, without the aid of this man, they
would ever have extricated themselves from these scarcely
penetrable woods. As it was, one seaman died on the march,
from fatigue. The Indians in these excursions steer by the
sun; so that if there is a continuance of cloudy weather, they
cannot travel.

The day was beautiful, and the number of trees which
tfere in full flower perfumed the air; yet even this could
fiardly dissipate the effects of the gloomy dampness of the
forest. Moreover, the many dead trunks that stand like
skeletons, never fail to give to these primeval woods a char-
acter of solemnity, absent in those of countries long civilized.
Shortly after sunset we bivouacked for the night. Our fe-
male companion, who was rather good-looking, belonged to
one of the most respectable families in Castro: she rode,
however, astride, and without shoes or stockings. I was sur-
prised at the total want of pride shown by her and her brother.
They brought food with them, but at all our meals sat

312 CHARLES DARWIN

watching Mr. King and myself whilst eating, till we were
fairly shamed into feeding the whole party. The night was
cloudless; and while lying in our beds, we enjoyed the sight
(and it is a high enjoyment) of the multitude of stars which
illumined the darkness of the forest.

January 2$rd. — We rose early in the morning, and reached
the pretty quiet town of Castro by two o'clock. The old gov-
ernor had died since our last visit, and a Chileno was acting
in his place. We had a letter of introduction to Don Pedro,
whom we found exceedingly hospitable and kind, and more
disinterested than is usual on this side of the continent. The
next day Don Pedro procured us fresh horses, and offered
to accompany us himself. We proceeded to the south — gen-
erally following the coast, and passing through several ham-
lets, each with it's large barn-like chapel built of wood. At
Vilipilli, Don Pedro asked the commandant to give us a guide
to Cucao. The old gentleman offered to come himself; but
for a long time nothing would persuade him that two En-
glishmen really wished to go to such an out-of-the-way place
as Cucao. We were thus accompanied by the two greatest
aristocrats in the country, as was plainly to be seen in the
manner of all the poorer Indians towards them. At Chonchi
we struck across the island, following intricate winding
paths, sometimes passing through magnificent forests, and
sometimes through pretty cleared spots, abounding with corn
and potato crops. This undulating woody country, partially
cultivated, reminded me of the wilder parts of England, and
therefore had to my eye a most fascinating aspect. At Vi-
linco, which is situated on the borders of the lake of Cucao,
only a few fields were cleared; and all the inhabitants ap-
peared to be Indians. This lake is twelve miles long, and
runs in an east and west direction. From local circum-
stances, the sea-breeze blows very regularly during the day,
and during the night it falls calm: this has given rise to
strange exaggerations, for the phenomenon, as described to
us at S. Carlos, was quite a prodigy.

The road to Cucao was so very bad that we determined to
embark in a periagua. The commandant, in the most au-
thoritative manner, ordered six Indians to get ready to pull
us over, without deigning to tell them whether they would

THE VOYAGE OF THE BEAGLE 313

be paid. The periagua is a strange rough boat, but the crew
were still stranger: I doubt if six uglier little men ever got
into a boat together. They pulled, however, very well and
cheerfully. The stroke-oarsman gabbled Indian, and uttered
strange cries, much after the fashion of a pig-driver driving
his pigs. We started with a light breeze against us, but yet
reached the Capella de Cucao before it was late. The coun-
try on each side of the lake was one unbroken forest. In the
same periagua with us, a cow was embarked. To get so
large an animal into a small boat appears at first a difficulty,
but the Indians managed it in a minute. They brought the
cow alongside the boat, which was heeled towards her; then
placing two oars under her belly, with their ends resting on
the gunwale, by the aid of these levers they fairly tumbled
the poor beast heels over head into the bottom of the boat,
and then lashed her down with ropes. At Cucao we found
an uninhabited hovel (which is the residence of the padre
when he pays this Capella a visit), where, lighting a fire, we
cooked our supper, and were very comfortable.

The district of Cucao is the only inhabited part on the
whole west coast of Chiloe. It contains about thirty or forty
Indian families, who are scattered along four or five miles
of the shore. They are very much secluded from the rest of
Chiloe, and have scarcely any sort of commerce, except
sometimes in a little oil, which they get from seal-blubber.
They are tolerably dressed in clothes of their own manu-
facture, and they have plenty to eat. They seemed, however,
discontented, yet humble to a degree which it was quite pain-
ful to witness. These feelings are, I think, chiefly to be
attributed to the harsh and authoritative manner in which
they are treated by their rulers. Our companions, although
so very civil to us, behaved to the poor Indians as if they
had been slaves, rather than free men. They ordered pro-
visions and the use of their horses, without ever condescend-
ing to say how much, or indeed whether the owners should
be paid at all. In the morning, being left alone with these
poor people, we soon ingratiated ourselves by presents of
cigars and mate. A lump of white sugar was divided be-
tween all present, and tasted with the greatest curiosity. The
Indians ended all their complaints by saying, "And it is only

314 CHARLES DARWIN

because we are poor Indians, and know nothing; but it was
not so when we had a King."

The next day after breakfast, we rode a few miles north-
ward to Punta Huantamo. The road lay along a very broad
beach, on which, even after so many fine days, a terrible surf
was breaking. I was assured that after a heavy gale, the
roar can be heard at night even at Castro, a distance of no
less than twenty-one sea-miles across a hilly and wooded
country. We had some difficulty in reaching the point, owing
to the intolerably bad paths; for everywhere in the shade
the ground soon becomes a perfect quagmire. The point
itself is a bold rocky hill. It is covered by a plant allied, I
believe, to Bromelia, and called by the inhabitants depones.
In scrambling through the beds, our hands were very much
scratched. I was amused by observing the precaution our
Indian guide took, in turning up his trousers, thinking that
they were more delicate than his own hard skin. This plant
bears a fruit, in shape like an artichoke, in which a number
of seed-vessels are packed: these contain a pleasant sweet
pulp, here much esteemed. I saw at Low's Harbour the
Chilotans making chichi, or cider, with this fruit : so true is
it, as Humboldt remarks, that almost everywhere man finds
means of preparing some kind of beverage from the vege-
table kingdom. The savages, however, of Tierra del Fuego,
and I believe of Australia, have not advanced thus far in
the arts.

The coast to the north of Punta Huantamo is exceedingly
rugged and broken, and is fronted by many breakers, on
which the sea is eternally roaring. Mr. King and myself
were anxious to return, if it had been possible, on foot along
this coast; but even the Indians said it was quite imprac-
ticable. We were told that men have crossed by striking
directly through the woods from Cucao to S. Carlos, but
never by the coast. On these expeditions, the Indians carry
with them only roasted corn, and of this they eat sparingly
twice a day.

26th. — Re-embarking in the periagua, we returned across
the lake, and then mounted our horses. The whole of Chiloe
took advantage of this week of unusually fine weather, to
clear the ground by burning. In every direction volumes of

THE VOYAGE OF THE BEAGLE 315

smoke were curling upwards. Although the inhabitants were
so assiduous in setting fire to every part of the wood, yet
I did not see a single fire which they had succeeded in mak-
ing extensive. We dined with our friend the commandant,
and did not reach Castro till after dark. The next morning
we Started very early. After having ridden for some time,
we obtained from the brow of a steep hill an extensive view
(and it is a rare thing on this road) of the great forest.
Over the horizon of trees, the volcano of Corcovado, and
the great flat-topped one to the north, stood out in proud
pre-eminence : scarcely another peak in the long range
showed its snowy summit. I hope it will be long before I
forget this farewell view of the magnificent Cordillera front-
ing Chiloe. At night we bivouacked under a cloudless sky,
and the next morning reached S. Carlos. We arrived on the
right day, for before evening heavy rain commenced.

February 4th. — Sailed from Chiloe. During the last week
I made several short excursions. One was to examine a
great bed of now-existing shells, elevated 350 feet above
the level of the sea: from among these shells, large forest-
trees were growing. Another ride was to P. Huechucucuy.
I had with me a guide who knew the country far too well;
for he would pertinaciously tell me endless Indian names for
every little point, rivulet, and creek. In the same manner as
in Tierra del Fuego, the Indian language appears singularly
well adapted for attaching names to the most trivial fea-
tures of the land. I believe every one was glad to say fare-
well to Chiloe; yet if we could forget the gloom and cease-
less rain of winter, Chiloe might pass for a charming island.
There is also something very attractive in the simplicity and
humble politeness of the poor inhabitants.

We steered northward along shore, but owing to thick
weather did not reach Valdivia till the night of the 8th. The
next morning the boat proceeded to the town, which is dis-
tant about ten miles. We followed the course of the river,
occasionally passing a few hovels, and patches of ground
cleared out of the otherwise unbroken forest ; and sometimes
meeting a canoe with an Indian family. The town is situ-
ated on the low banks of the stream, and is so completely
buried in a wood of apple-trees that the streets are merely

316 CHARLES DARWIN

paths in an orchard. I have never seen any country, where
apple-trees appeared to thrive so well as in this damp part of
South America: on the borders of the roads there were
many young trees evidently self-grown. In Chiloe the in-
habitants possess a marvellously short method of making an
orchard. At the lower part of almost every branch, small,
conical, brown, wrinkled points project: these are always
ready to change into roots, as may sometimes be seen, where
any mud has been accidentally splashed against the tree. A
branch as thick as a man's thigh is chosen in the early spring,
and is cut off just beneath a group of these points, all the
smaller branches are lopped off, and it is then placed about
two feet deep in the ground. During the ensuing summer
the stump throws out long shoots, and sometimes even bears
fruit: I was shown one which had produced as many as
twenty-three apples, but this was thought very unusual. In
the third season the stump is changed (as I have myself
seen) into a well- wooded tree, loaded with fruit. An old
man near Valdivia illustrated his motto, " Necesidad es la
madre del invencion," by giving an account of the several
useful things he manufactured from his apples. After mak-
ing cider, and likewise wine, he extracted from the refuse a
white and finely flavoured spirit; by another process he pro-
cured a sweet treacle, or, as he called it, honey. His children
and pigs seemed almost to live, during this season of the
year, in his orchard.

February nth. — I set out with a guide on a short ride, in
which, however, I managed to see singularly little, either
of the geology of the country or of its inhabitants. There
is not much cleared land near Valdivia: after crossing a
river at the distance of a few miles, we entered the forest, and
then passed only one miserable hovel, before reaching our
sleeping-place for the night. The short difference in lati-
tude, of 150 miles, has given a new aspect to the forest, com-
pared with that of Chiloe. This is owing to a slightly
different proportion in the kinds of trees. The evergreens
do not appear to be quite so numerous, and the forest in
consequence has a brighter tint. As in Chiloe, the lower
parts are matted together by canes: here also another kind
(resembling the bamboo of Brazil and about twenty feet in

THE VOYAGE OF THE BEAGLE 31?

height) grows in clusters, and ornaments the banks of some
of the streams in a very pretty manner. It is with this plant
that the Indians make their chuzos, or long tapering spears.
Our resting-house was so dirty that I preferred sleeping out-
side: on these journeys the first night is generally very un-
comfortable, because one is not accustomed to the tickling
and biting of the fleas. I am sure, in the morning, there
was not a space on my legs the size of a shilling which had
not its little red mark where the flea had feasted.

1 2th. — We continued to ride through the uncleared forest ;
only occasionally meeting an Indian on horseback, or a troop
of fine mules bringing alerce-planks and corn from the south-
ern plains. In the afternoon one of the horses knocked up:
we were then on a brow of a hill, which commanded a fine
view of the Llanos. The view of these open plains was very
refreshing, after being hemmed in and buried in the wilder-
ness of trees. The uniformity of a forest soon becomes very
wearisome. This west coast makes me remember with pleas-
ure the free, unbounded plains of Patagonia; yet, with the
true spirit of contradiction, I cannot forget how sublime is
the silence of the forest. The Llanos are the most fertile
and thickly peopled parts of the country, as they possess the
immense advantage of being nearly free from trees. Before
leaving the forest we crossed some flat little lawns, around
which single trees stood, as in an English park : I have often
noticed with surprise, in wooded undulatory districts, that
the quite level parts have been destitute of trees. On ac-
count of the tired horse, I determined to stop at the Mission
of Cudico, to the friar of which I had a letter of introduc-
tion. Cudico is an intermediate district between the forest
and the Llanos. There are a good many cottages, with
patches of corn and potatoes, nearly all belonging to Indians.
The tribes dependent on Valdivia are " reducidos y cris-
tianos." The Indians farther northward, about Arauco and
Imperial, are still very wild, and not converted; but they
have all much intercourse with the Spaniards. The padre
said that the Christian Indians did not much like coming
to mass, but that otherwise they showed respect for religion.
The greatest difficulty is in making them observe the cere-
monies of marriage. The wild Indians take as many wives

318 CHARLES DARWIN

as they can support, and a cacique will sometimes have more
than ten : on entering his house, the number may be told by
that of the separate fires. Each wife lives a week in turn
with the cacique; but all are employed in weaving ponchos,
etc., for his profit. To be the wife of a cacique, is an honour
much sought after by the Indian women.

The men of all these tribes wear a coarse woolen poncho :
those south of Valdivia wear short trousers, and those north
of it a petticoat, like the chilipa of the Gauchos. All have
their long hair bound by a scarlet fillet, but with no other
covering on their heads. These Indians are good-sized men ;
their cheek-bones are prominent, and in general appearance
they resemble the great American family to which they be-
long; but their physiognomy seemed to me to be slightly
different from that of any other tribe which I had before
seen. Their expression is generally grave, and even austere,
and possesses much character : this may pass either for hon-
est bluntness or fierce determination. The long black hair,
the grave and much-lined features, and the dark complexion,
called to my mind old portraits of James I. On the road we
met with none of that humble politeness so universal in
Chiloe. Some gave their " mari-mari " (good morning) with
promptness, but the greater number did not seem inclined to
offer any salute. This independence of manners is probably
a consequence of their long wars, and the repeated victories
which they alone, of all the tribes in America, have gained
over the Spaniards.

I spent the evening very pleasantly, talking with the
padre. He was exceedingly kind and hospitable ; and coming
from Santiago, had contrived to surround himself with some
few comforts. Being a man of some little education, he bit-
terly complained of the total want of society. With no par-
ticular zeal for religion, no business or pursuit, how com-
pletely must this man's life be wasted! The next day, on
our return, we met seven very wild-looking Indians, of whom
some were caciques that had just received from the Chilian
government their yearly small stipend for having long re-
mained faithful. They were fine-looking men, and they rode
one after the other, with most gloomy faces. An old cacique,
who headed them, had been, I suppose, more excessively

THE VOYAGE OF THE BEAGLE 319

drunk than the rest, for he seemed extremely grave and
very crabbed. Shortly before this, two Indians joined us,
who were travelling from a distant mission to Valdivia con-
cerning some lawsuit. One was a good-humoured old man,
but from his wrinkled beardless face looked more like an
old woman than a man. I frequently presented both of them
with cigars; and though ready to receive them, and I dare
say grateful, they would hardly condescend to thank me. A
Chilotan Indian would have taken off his hat, and given his
" Dios le page ! " The travelling was very tedious, both
from the badness of the roads, and from the number of great
fallen trees, which it was necessary either to leap over or to
avoid by making long circuits. We slept on the road, and
next morning reached Valdivia, whence I proceeded on
board.

A few days afterwards I crossed the bay with a party of
officers, and landed near the fort called Niebla. The build-
ings were in a most ruinous state, and the gun-carriages
quite rotten. Mr. Wickham remarked to the commanding
officer, that with one discharge they would certainly all fall
to pieces. The poor man, trying to put a good face upon it,
gravely replied, " No, I am sure, sir, they would stand
two I " The Spaniards must have intended to have made this
place impregnable. There is now lying in the middle of the
court-yard a little mountain of mortar, which rivals in hard-
ness the rock on which it is placed. It was brought from
Chile, and cost 7000 dollars. The revolution having broken
out, prevented its being applied to any purpose, and now it
remains a monument of the fallen greatness of Spain.

I wanted to go to a house about a mile and a half distant,
but my guide said it was quite impossible to penetrate the
wood in a straight line. He offered, however, to lead me, by
following obscure cattle-tracks, the shortest way: the walk,
nevertheless, took no less than three hours ! This man is
employed in hunting strayed cattle; yet, well as he must
know the woods, he was not long since lost for two whole
days, and had nothing to eat. These facts convey a good
idea of the impracticability of the forests of these countries.
A question often occurred to me — how long does any vestige
of a fallen tree remain? This man showed me one which

320 CHARLES DARWIN

a party of fugitive royalists had cut down fourteen years
ago ; and taking this as a criterion, I should think a bole a
foot and a half in diameter would in thirty years be changed
into a heap of mould.

February 20th. — This day has been memorable in the
annals of Valdivia, for the most severe earthquake experi-
enced by the oldest inhabitant. I happened to be on shore,
and was lying down in the wood to rest myself. It came on
suddenly, and lasted two minutes, but the time appeared
much longer. The rocking of the ground was very sensible.
The undulations appeared to my companion and myself to
come from due east, whilst others thought they proceeded
from south-west: this shows how difficult it sometimes is to
perceive the directions of the vibrations. There was no diffi-
culty in standing upright, but the motion made me almost
giddy: it was something like the movement of a vessel in a
little cross-rip*ple, or still more like that felt by a person skat-
ing over thin ice, which bends under the weight of his body.

A bad earthquake at once destroys our oldest associations :
the earth, the very emblem of solidity, has moved beneath
our feet like a thin crust over a fluid; — one second of time
has created in the mind a strange idea of insecurity, which
hours of reflection would not have produced. In the forest,
as a breeze moved the trees, I felt only the earth tremble, but
saw no other effect. Captain Fitz Roy and some officers
were at the town during the shock, and there the scene was
more striking; for although the houses, from being built of
wood, did not fall, they were violently shaken, and the boards
creaked and rattled together. The people rushed out of
doors in the greatest alarm. It is these accompaniments that
create that perfect horror of earthquakes, experienced by all
who have thus seen, as well as felt, their effects. Within the
forest it was a deeply interesting, but by no means an awe-
exciting phenomenon. The tides were very curiously affected.
The great shock took place at the time of low water;
and an old woman who was on the beach told me that the
water flowed very quickly, but not in great waves, to high-
water mark, and then as quickly returned to its proper level ;
this was also evident by the line of wet sand. The same kind
of quick but quiet movement in the tide happened a few

THE VOYAGE OF THE BEAGLE

321

years since at Chiloe, during a slight earthquake, and created
much causeless alarm. In the course of the evening there
were many weaker shocks, which seemed to produce in the
harbour the most complicated currents, and some of great
strength.

March 4th. — We entered the harbour of Concepcion. While
the ship was beating up to the anchorage, I landed on the
island of Quiriquina. The mayor-domo of the estate quickly
rode down to tell me the terrible news of the great earth-
quake of the 20th: — "That not a house in Concepcion or
Talcahuano (the port) was standing; that seventy villages
were destroyed; and that a great wave had almost washed
away the ruins of Talcahuano." Of this latter statement I
soon saw abundant proofs — the whole coast being strewed
over with timber and furniture as if a thousand ships had
been wrecked. Besides chairs, tables, book-shelves, etc., in
great numbers, there were several roofs of cottages, which
had been transported almost whole. The storehouses at Tal-
cahuano had been burst open, and great bags of cotton, yerba,
and other valuable merchandise were scattered on the shore.
During my walk round the island, I observed that numerous
fragments of rock, which, from the marine productions ad-
hering to them, must recently have been lying in deep water,
had been cast up high on the beach ; one of these was six feet
long, three broad, and two thick.

The island itself as plainly showed the overwhelming
power of the earthquake, as the beach did that of the conse-
quent great wave. The ground in many parts was fissured
in north and south lines, perhaps caused by the yielding of
the parallel and steep sides of this narrow island. Some of
the fissures near the cliffs were a yard wide. Many enormous
masses had already fallen on the beach; and the inhabitants
thought that when the rains commenced far greater slips would
happen. The effect of the vibration on the hard primary slate,
which composes the foundation of the island, was still more
curious: the superficial parts of some narrow ridges were as
completely shivered as if they had been blasted by gun-
powder. This effect, which was rendered conspicuous by the
fresh fractures and displaced soil, must be confined to near

VOL. XXIX — K

322 CHARLES DARWIN

the surface, for otherwise there would not exist a block of
solid rock throughout Chile; nor is this improbable, as it is
known that the surface of a vibrating body is affected differ-
ently from the central part. It is, perhaps, owing to this
same reason, that earthquakes do not cause quite such terrific
havoc within deep mines as would be expected. I believe this
convulsion has been more effectual in lessening the size of
the island of Quiriquina, than the ordinary wear-and-tear
of the sea and weather during the course of a whole century.
The next day I landed at Talcahuano, and afterwards rode
to Concepcion. Both towns presented the most awful yet
interesting spectacle I ever beheld. To a person who had
formerly know them, it possibly might have been still more
impressive; for the ruins were so mingled together, and the
whole scene possessed so little the air of a habitable place,
that it was scarcely possible to imagine its former condition.
The earthquake commenced at half-past eleven o'clock in the
forenoon. If it had happened in the middle of the night, the
greater number of the inhabitants (which in this one prov-
ince must amount to many thousands) must have perished,
instead of less than a hundred : as it was, the invariable prac-
tice of running out of doors at the first trembling of the
ground, alone saved them. In Concepcion each house, or
row of houses, stood by itself, a heap or line of ruins ; but in
Talcahuano, owing to the great wave, little more than one
layer of bricks, tiles, and timber, with here and there part of
a wall left standing, could be distinguished. From this circum-
stance Concepcion, although not so completely desolated, was
a more terrible, and if I may so call it, picturesque sight.
The first shock was very sudden. The mayor-domo at Quiri-
quina told me, that the first notice he received of it, was
finding both the horse he rode and himself, rolling together
on the ground. Rising up, he was again thrown down. He
also told me that some cows which were standing on the steep
side of the island were rolled into the sea. The great wave
caused the destruction of many cattle; on one low island,
near the head of the bay, seventy animals were washed off
and drowned. It is generally thought that this has been the
worst earthquake ever recorded in Chile; but as the very
severe ones occur only after long intervals, this cannot easily

THE VOYAGE OF THE BEAGLE 323

be known ; nor indeed would a much worse shock have made
any difference, for the ruin was now complete. Innumerable
small tremblings followed the great earthquake, and within
the first twelve days no less than three hundred were counted.

After viewing Concepcion, I cannot understand how the
greater number of inhabitants escaped unhurt. The houses
in many parts fell outwards; thus forming in the middle of
the streets little hillocks of brickwork and rubbish. Mr.
Rouse, the English consul, told us that he was at breakfast
when the first movement warned him to run out. He had
scarcely reached the middle of the court-yard, when one side
of his house came thundering down. He retained presence
of mind to remember, that if he once got on the top of that
part which had already fallen, he would be safe. Not being
able from the motion of the ground to stand, he crawled up
on his hands and knees; and no sooner had he ascended this
little eminence, than the other side of the house fell in, the
great beams sweeping close in front of his head. With his
eyes blinded, and his mouth choked with the cloud of dust
which darkened the sky, at last he gained the street. As
shock succeeded shock, at the interval of a few minutes, no
one dared approach the shattered ruins; and no one knew
whether his dearest friends and relations were not perish-
ing from the want of help. Those who had saved any prop-
erty were obliged to keep a constant watch, for thieves
prowled about, and at each little trembling of the ground,
with one hand they beat their breasts and cried " Miseri-
cordia ! " and then with the other filched what they could
from the ruins. The thatched roofs fell over the fires, and
flames burst forth in all parts. Hundreds knew themselves
ruined, and few had the means of providing food for the day.

Earthquakes alone are sufficient to destroy the prosperity
of any country. If beneath England the now inert subter-
ranean forces should exert those powers, which most assur-
edly in former geological ages they have exerted, how com-
pletely would the entire condition of the country be changed !
What would become of the lofty houses, thickly packed cities,
great manufactories, the beautiful public and private edi-
fices? If the new period of disturbance were first to com-
mence by some great earthquake in the dead of the night,

324 CHARLES DARWIN

how terrific would be the carnage ! England would at once
be bankrupt; all papers, records, and accounts would from
that moment be lost. Government being unable to collect
the taxes, and failing to maintain its authority, the hand of
violence and rapine would remain uncontrolled. In every
large town famine would go forth, pestilence and death fol-
lowing in its train.

Shortly after the shock, a great wave was seen from the
distance of three or four miles, approaching in the middle
of the bay with a smooth outline; but along the shore it tore
up cottages and trees, as it swept onwards with irresistible
force. At the head of the bay it broke in a fearful line of
white breakers, which rushed up to a height of 23 vertical
feet above the highest spring-tides. Their force must have
been prodigious ; for at the Fort a cannon with its carriage,
estimated at four tons in weight, was moved 15 feet inwards.
A schooner was left in the midst of the ruins, 200 yards
from the beach. The first wave was followed by two others,
which in their retreat carried away a vast wreck of floating
objects. In one part of the bay, a ship was pitched high
and dry on shore, was carried off, again driven on shore, and
again carried off. In another part, two large vessels anchored
near together were whirled about, and their cables were thrice
wound round each other; though anchored at a depth of 36
feet, they were for some minutes aground. The great wave
must have travelled slowly, for the inhabitants of Talca-
huano had time to run up the hills behind the town; and
some sailors pulled out seaward, trusting successfully to their
boat riding securely over the swell, if they could reach it
before it broke. One old woman with a little boy, four or
five years old, ran into a boat, but there was nobody to row
it out: the boat was consequently dashed against an anchor
and cut in twain ; the old woman was drowned, but the child
was picked up some hours afterwards clinging to the wreck.
Pools of salt-water were still standing amidst the ruins of
the houses, and children, making boats with old tables and
chairs, appeared as happy as their parents were miserable.
It was, however, exceedingly interesting to observe, how
much more active and cheerful all appeared than could have
been expected. It was remarked with much truth, that from

THE VOYAGE OF THE BEAGLE 325

the destruction being universal, no one individual was hum-
bled more than another, or could suspect his friends of cold-
ness— that most grievous result of the loss of wealth. Mr.
Rouse, and a large party whom he kindly took under his
protection, lived for the first week in a garden beneath some
apple-trees. At first they were as merry as if it had been a
picnic ; but soon afterwards heavy rain caused much discom-
fort, for they were absolutely without shelter.

In Captain Fitz Roy's excellent account of the earthquake,
it is said that two explosions, one like a column of smoke and
another like the blowing of a great whale, were seen in the
bay. The water also appeared everywhere to be boiling ; and
it " became black, and exhaled a most disagreeable sulphure-
ous smell." These latter circumstances were observed in the
Bay of Valparaiso during the earthquake of 1822 ; they may,
I think, be accounted for, by the disturbance of the mud at
the bottom of the sea containing organic matter in decay. In
the Bay of Callao, during a calm day, I noticed, that as the
ship dragged her cable over the bottom, its course was marked
by a line of bubbles. The lower orders in Talcahuano thought
that the earthquake was caused by some old Indian women,
who two years ago, being offended, stopped the volcano of
Antuco. This silly belief is curious, because it shows that
experience has taught them to observe, that there exists a
relation between the suppressed action of the volcanos, and
the trembling of the ground. It was necessary to apply the
witchcraft to the point where their perception of cause and
effect failed; and this was the closing of the volcanic vent.
This belief is the more singular in this particular instance,
because, according to Captain Fitz Roy, there is reason to
believe that Antuco was noways affected.

The town of Concepcion was built in the usual Spanish
fashion, with all the streets running at right angles to each
other; one set ranging S.W. by W., and the other set N.W.
by N. The walls in the former direction certainly stood
better than those in the latter; the greater number of the
masses of brickwork were thrown down towards the N.E.
Both these circumstances perfectly agree with the general
idea, of the undulations having come from the S.W., in which
quarter subterranean noises were also heard ; for it is evident

326 CHARLES DARWIN

that the walls running S.W. and N.E. which presented their
ends to the point whence the undulations came, would be
much less likely to fall than those walls which, running N.W.
and S.E., must in their whole lengths have been at the same
instant thrown out of the perpendicular ; for the undulations,
coming from the S.W., must have extended in N.W. and
S.E. waves, as they passed under the foundations. This may
be illustrated by placing books edgeways on a carpet, and
then, after the manner suggested by Michell, imitating the
undulations of an earthquake : it will be found that they fall
with more or less readiness, according as their direction more
or less nearly coincides with the line of the waves. The fis-
sures in the ground generally, though not uniformly, extended
in a S.E. and N.W. direction, and therefore corresponded
to the lines of undulation or of principal flexure. Bearing in
mind all these circumstances, which so clearly point to the
S.W. as the chief focus of disturbance, it is a very interesting
fact that the island of S. Maria, situated in that quarter, was,
during the general uplifting of the land, raised to nearly
three times the height of any other part of the coast.

The different resistance offered by the walls, according to
their direction, was well exemplified in the case of the Cathe-
dral. The side which fronted the N.E. presented a grand
pile of ruins, in the midst of which door-cases and masses
of timber stood up, as if floating in a stream. Some of the
angular blocks of brickwork were of great dimensions; and
they were rolled to a distance on the level plaza, like frag-
ments of rock at the base of some high mountain. The side
walls (running S.W. and N.E.), though exceedingly frac-
tured, yet remained standing; but the vast buttresses (at
right angles to them, and therefore parallel to the walls that
fell) were in many cases cut clean off, as if by a chisel, and
hurled to the ground. Some square ornaments on the cop-
ing of these same walls, were moved by the earthquake into
a diagonal position. A similar circumstance was observed
after an earthquake at Valparaiso, Calabria, and other places,
including some of the ancient Greek temples.1 This twist-
ing displacement, at first appears to indicate a vorticose

1 M. Arago in L'Institut, 1839, p. 337. See also Miers's Chile, vol. i. p.
392; also Ly ell's Principles of Geology, chap, xv., book ii.

THE VOYAGE OF THE BEAGLE 327

movement beneath each point thus affected ; but this is highly
improbable. May it not be caused by a tendency in each stone
to arrange itself in some particular position, with respect
to the lines of vibration, — in a manner somewhat similar to
pins on a sheet of paper when shaken ? Generally speaking,
arched doorways or windows stood much better than any
other part of the buildings. Nevertheless, a poor lame old
man, who had been in the habit, during trifling shocks, of
crawling to a certain doorway, was this time crushed to
pieces.

I have not attempted to give any detailed description of
the appearance of Concepcion, for I feel that it is quite impos-
sible to convey the mingled feelings which I experienced.
Several of the officers visited it before me, but their strongest
language failed to give a just idea of the scene of desolation.
It is a bitter and humiliating thing to see works, which have
cost man so much time and labour, overthrown in one min-
ute; yet compassion for the inhabitants was almost instantly
banished, by the surprise in seeing a state of things produced
in a moment of time, which one was accustomed to attribute
to a succession of ages. In my opinion, we have scarcely be-
held, since leaving England, any sight so deeply interesting.

In almost every severe earthquake, the neighbouring waters
of the sea are said to have been greatly agitated. The dis-
turbance seems generally, as in the case of Concepcion, to
have been of two kinds: first, at the instant of the shock,
the water swells high up on the beach with a gentle motion,
and then as quietly retreats ; secondly, some time afterwards,
the whole body of the sea retires from the coast, and then
returns in waves of overwhelming force. The first move-
ment seems to be an immediate consequence of the earth-
quake affecting differently a fluid and a solid, so that their
respective levels are slightly deranged: but the second case
is a far more important phenomenon. During most earth-
quakes, and especially during those on the west coast of
America, it is certain that the first great movement of the
waters has been a retirement. Some authors have attempted
to explain this, by supposing that the water retains its level,
whilst the land oscillates upwards ; but surely the water close
to the land, even on a rather steep coast, would partake of the

328 CHARLES DARWIN

motion of the bottom: moreover, as urged by Mr. Lyell,
similar movements of the sea have occurred at islands far
distant from the chief line of disturbance, as was the case
with Juan Fernandez during this earthquake, and with
Madeira during the famous Lisbon shock. I suspect (but the
subject is a very obscure one) that a wave, however produced,
first draws the water from the shore, on which it is advancing
to break: I have observed that this happens with the little
waves from the paddles of a steam-boat. It is remarkable
that whilst Talcahuano and Callao (near Lima), both situ-
ated at the head of large shallow bays, have suffered during
every severe earthquake from great waves, Valparaiso,
seated close to the edge of profoundly deep water, has never
been overwhelmed, though so often shaken by the severest
shocks. From the great wave not immediately following the
earthquake, but sometimes after the interval of even half an
hour, and from distant islands being affected similarly with
the coasts near the focus of the disturbance, it appears that
the wave first rises in the offing; and as this is of general
occurrence, the cause must be general: I suspect we must
look to the line, where the less disturbed waters of the deep
ocean join the water nearer the coast, which has partaken
of the movements of the land, as the place where the great
wave is first generated; it would also appear that the wave
is larger or smaller, according to the extent of shoal water
which has been agitated together with the bottom on which it
rested.

The most remarkable effect of this earthquake was the per-
manent elevation of the land ; it would probably be far more
correct to speak of it as the cause. There can be no doubt
that the land round the Bay of Concepcion was upraised
two or three feet; but it deserves notice, that owing to the
wave having obliterated the old lines of tidal action on the
sloping sandy shores, I could discover no evidence of this
fact, except in the united testimony of the inhabitants, that
one little rocky shoal, now exposed, was formerly covered
with water. At the island of S. Maria (about thirty miles
distant) the elevation was greater; on one part, Captain Fitz
Roy founds beds of putrid mussel-shells still adhering to the

THE VOYAGE OF THE BEAGLE 329

rocks, ten feet above high-water mark: the inhabitants had
formerly dived at lower-water spring-tides for these shells.
The elevation of this province is particularly interesting,
from its having been the theatre of several other violent
earthquakes, and from the vast numbers of sea-shells scat-
tered over the land, up to a height of certainly 600, and I
believe, of 1000 feet. At Valparaiso, as I have remarked,
similar shells are found at the height of 1300 feet: it is hardly
possible to doubt that this great elevation has been effected
by successive small uprisings, such as that which accompa-
nied or caused the earthquake of this year, and likewise by
an insensibly slow rise, which is certainly in progress on
some parts of this coast.

The island of Juan Fernandez, 360 miles to the N.E., was,
at the time of the great shock of the 2Oth, violently shaken,
so that the trees beat against each other, and a volcano burst
forth under water close to the shore : these facts are remark-
able because this island, during the earthquake of 1751, was
then also affected more violently than other places at an equal
distance from Concepcion, and this seems to show some sub-
terranean connection between these two points. Chiloe, about
340 miles southward of Concepcion, appears to have been
shaken more strongly than the intermediate district of Val-
divia, where the volcano of Villarica was noways affected,
whilst in the Cordillera in front of Chiloe, two of the vol-
canos burst -forth at the same instant in violent action. These
two volcanos, and some neighbouring ones, continued for a
long time in eruption, and ten months afterwards were
again influenced by an earthquake at Concepcion. Some
men, cutting wood near the base of one of these volcanos,
did not perceive the shock of the 20th, although the whole
surrounding Province was then trembling; here we have an
eruption relieving and taking the place of an earthquake,
as would have happened at Concepcion, according to the
belief of the lower orders, if the volcano at Antuco had not
been closed by witchcraft. Two years and three-quarters
afterwards, Valdivia and Chiloe were again shaken, more
violently than on the 2oth, and an island in the Chonos
Archipelago was permanently elevated more than eight feet.
It will give a better idea of the scale of these phenomena, if

330 CHARLES DARWIN

(as in the case of the glaciers) we suppose them to have
taken place at corresponding distances in Europe : — then
would the land from the North Sea to the Mediterranean
have been violently shaken, and at the same instant of time a
large tract of the eastern coast of England would have been
permanently elevated, together with some outlying islands, — a
train of volcanos on the coast of Holland would have burst
forth in action, and an eruption taken place at the bottom of
the sea, near the northern extremity of Ireland — and lastly,
the ancient vents of Auvergne, Cantal, and Mont d'Or would
each have sent up to the sky a dark column of smoke, and
have long remained in fierce action. Two years and three-
quarters afterwards, France, from its centre to the English
Channel, would have been again desolated by an earthquake,
and an island permanently upraised in the Mediterranean.

The space, from under which volcanic matter on the 20th
was actually erupted, is 720 miles in one line, and 400 miles
in another line at right angles to the first : hence, in all prob-
ability, a subterranean lake of lava is here stretched out, of
nearly double the area of the Black Sea. From the intimate
and complicated manner in- which the elevatory and eruptive
forces were shown to be connected during this train of phe-
nomena, we may confidently come to the conclusion, that the
forces which slowly and by little starts uplift continents, and
those which at successive periods pour forth volcanic matter
from open orifices, are identical. From many reasons, I
believe that the frequent quakings of the earth on this line
of coast are caused by the rending of the strata, necessarily
consequent on the tension of the land when upraised, and
their injection by fluidified rock. This rending and injection
would, if repeated often enough (and we know that earth-
quakes repeatedly affect the same areas in the same manner),
form a chain of hills; — and the linear island of S. Mary,
which was upraised thrice the height of the neighbouring
country, seems to be undergoing this process. I believe that
the solid axis of a mountain, differs in its manner of forma-
tion from a volcanic hill, only in the molten stone having
been repeatedly injected, instead of having been repeatedly
ejected. Moreover, I believe that it is impossible to explain
the structure of great mountain-chains, such as that of the

THE VOYAGE OF THE BEAGLE 331

Cordillera, where the strata, capping the injected axis of
plutonic rock, have been thrown on their edges along several
parallel and neighbouring lines of elevation, except on this
view of the rock of the axis having been repeatedly injected,
after intervals sufficiently long to allow the upper parts or
wedges to cool and become solid; — for if the strata had been
thrown into their present highly inclined, vertical, and even
inverted positions, by a single blow, the very bowels of the
earth would have gushed out ; and instead of beholding abrupt
mountain-axes of rock solidified under great pressure, deluges
of lava would have flowed out at innumerable points on every
line of elevation.*

3 For a full account of the volcanic phenomena which accompanied the
earthquake of the aoth, and for the conclusions deducible from them, I must
refer to Volume V. of the Geological Transactions.

?th, 1835. — We stayed three days at Concep-
cion, and then sailed for Valparaiso. The wind
being northerly, we only reached the mouth of the
harbour of Concepcion before it was dark. Being very near
the land, and a fog coming on, the anchor was dropped.
Presently a large American whaler appeared alongside of us ;
and we heard the Yankee swearing at his men to keep quiet,
whilst he listened for the breakers. Captain Fitz Roy hailed
him, in a loud clear voice, to anchor where he then was. The
poor man must have thought the voice came from the shore :
such a Babel of cries issued at once from the ship — every
one hallooing out, " Let go the anchor ! veer cable ! shorten
sail ! " It was the most laughable thing I ever heard. If
the ship's crew had been all captains, and no men, there could
not have been a greater uproar of orders. We afterwards
found that the mate stuttered: I suppose all hands were
assisting him in giving his orders.

On the nth we anchored at Valparaiso, and two days
afterwards I set out to cross the Cordillera. I proceeded to
Santiago, where Mr. Caldcleugh most kindly assisted me in
every possible way in making the little preparations which
were necessary. In this part of Chile there are two passes
across the Andes to Mendoza: the one most commonly used
— namely, that of Aconcagua or Uspallata — is situated some

332

THE VOYAGE OF THE BEAGLE 333

way to the north; the other, called the Portillo, is to the
south, and nearer, but more lofty and dangerous.

March i8th. — We set out for the Portillo pass. Leaving
Santiago we crossed the wide burnt-up plain on which that
city stands, and in the afternoon arrived at the Maypu, one
of the principal rivers in Chile. The valley, at the point
where it enters the first Cordillera, is bounded on each side
by lofty barren mountains; and although not broad, it is very
fertile. Numerous cottages were surrounded by vines, and by
orchards of apple, nectarine, and peach-trees — their boughs
breaking with the weight of the beautiful ripe fruit. In the
evening we passed the custom-house, where our luggage was
examined. The frontier of Chile is better guarded by the
Cordillera, than by the waters of the sea. There are very
few valleys which lead to the central ranges, and the
mountains are quite impassable in other parts by beasts of
burden. The custom-house officers were very civil, which
was perhaps partly owing to the passport which the President
of the Republic had given me ; but I must express my admira-
tion at the natural politeness of almost every Chileno. In
this instance, the contrast with the same class of men in
most other countries was strongly marked. I may mention
an anecdote with which I was at the time much pleased : we
met near Mendoza a little and very fat negress, riding astride
on a mule. She had a goitre so enormous that it was scarcely
possible to avoid gazing at her for a moment; but my two
companions almost instantly, by way of apology, made the
common salute of the country by taking off their hats. Where
would one of the lower or higher classes in Europe, have
shown such feeling politeness to a poor and miserable object
of a degraded race?

At night we slept at a cottage. Our manner of travelling
was delightfully independent. In the inhabited parts we
bought a little firewood, hired pasture for the animals, and
bivouacked in the corner of the same field with them. Car-
rying an iron pot, we cooked and ate our supper under a
cloudless sky, and knew no trouble. My companions were
Mariano Gonzales, who had formerly accompanied me in
Chile, and an " arriero," with his ten mules and a " madrina."
The madrina (or godmother) is a most important personage:

334 CHARLES DARWIN

she is an old steady mare, with a little bell round her neck;
and wherever she goes, the mules, like good children, follow
her. The affection of these animals for their madrinas saves
infinite trouble. If several large troops are turned into one
field to graze, in the morning the muleteers have only to lead
the madrinas a little apart, and tinkle their bells; although
there may be two or three hundred together, each mule im-
mediately knows the bell of its own madrina, and comes to
her. It is nearly impossible to lose an old mule; for if
detained for several hours by force, she will, by the power
of smell, like a dog, track out her companions, or rather the
madrina, for, according to the muleteer, she is the chief
object of affection. The feeling, however, is not of an indi-
vidual nature; for I believe I am right in saying that any
animal with a bell will serve as a madrina. In a troop each
animal carries on a level road, a cargo weighing 416 pounds
(more than 29 stone), but in a mountainous country 100
pounds less; yet with what delicate slim limbs, without any
proportional bulk of muscle, these animals support so great
a burden ! The mule always appears to me a most surprising
animal. That a hybrid should possess more reason, memory,
obstinacy, social affection, powers of muscular endurance,
and length of life, than either of its parents, seems to indi-
cate that art has here outdone nature. Of our ten animals,
six were intended for riding, and four for carrying cargoes,
each taking turn about. We carried a good deal of food, in
case we should be snowed up, as the season was rather late
for passing the Portillo.

March ipth. — We rode during this day to the last, and
therefore most elevated, house in the valley. The number of
inhabitants became scanty; but wherever water could be
brought on the land, it was very fertile. All the main valleys
in the Cordillera are characterized by having, on both sides, a
fringe or terrace of shingle and sand, rudely stratified, and
generally of considerable thickness. These fringes evidently
once extended across the valleys and were united; and the
bottoms of the valleys in northern Chile, where there are no
streams, are thus smoothly filled up. On these fringes the
roads are generally carried, for their surfaces are even, and
they rise with a very gentle slope up the valleys : hence, also,

THE VOYAGE OF THE BEAGLE 335

they are easily cultivated by irrigation. They may be traced
up to a height of between 7000 and 9000 feet, where they
become hidden by the irregular piles of debris. At the lower
end or mouths of the valleys, they are continuously united to
those land-locked plains (also formed of shingle) at the foot
of the main Cordillera, which I have described in a former
chapter as characteristic of the scenery of Chile, and which
were undoubtedly deposited when the sea penetrated Chile, as
it now does the more southern coasts. No one fact in the
geology of South America, interested me more than these
terraces of rudely-stratified shingle. They precisely resemble
in composition the matter which the torrents in each valley
would deposit, if they were checked in their course by any
cause, such as entering a lake or arm of the sea; but the
torrents, instead of depositing matter, are now steadily at
work wearing away both the solid rock and these alluvial
deposits, along the whole line of every main valley and side
valley. It is impossible here to give the reasons, but I am
convinced that the shingle terraces were accumulated, during
the gradual elevation of the Cordillera, by the torrents
delivering, at successive levels, their detritus on the beach-
heads of long narrow arms of the sea, first high up the val-
leys, then lower and lower down as the land slowly rose. If
this be so, and I cannot doubt it, the grand and broken chain
of the Cordillera, instead of having been suddenly thrown up,
as was till lately the universal, and still is the common opinion
of geologists, has been slowly upheaved in mass, in the same
gradual manner as the coasts of the Atlantic and Pacific have
risen within the recent period. A multitude of facts in the
structure of the Cordillera, on this view receive a simple
explanation.

The rivers which flow in these valleys ought rather to be
called mountain-torrents. Their inclination is very great,
and their water the colour of mud. The roar which the
Maypu made, as it rushed over the great rounded fragments,
was like that of the sea. Amidst the din of rushing waters,
the noise from the stones, as they rattled one over another,
was most distinctly audible even from a distance. This rat-
tling noise, night and day, may be heard along the whole
course of the torrent. The sound spoke eloquently to the

336 CHARLES DARWIN

geologist; the thousands and thousands of stones, which,
striking against each other, made the one dull uniform sound,
were all hurrying in one direction. It was like thinking on
time, where the minute that now glides past is irrevocable.
So was it with these stones ; the ocean is their eternity, and
each note of that wild music told of one more step towards
their destiny.

It is not possible for the mind to comprehend, except by
a slow process, any effect which is produced by a cause re-
peated so often, that the multiplier itself conveys an idea,
not more definite than the savage implies when he points to
the hairs of his head. As often as I have seen beds of mud,
sand, and shingle, accumulated to the thickness of many
thousand feet, I have felt inclined to exclaim that causes,
such as the present rivers and the present beaches, could
never have ground down and produced such masses. But, on
the other hand, when listening to the rattling noise of these
torrents, and calling to mind that whole races of animals have
passed away from the face of the earth, and that during this
whole period, night and day, these stones have gone rattling
onwards in their course, I have thought to myself, can any
mountains, any continent, withstand such waste?

In this part of the valley, the mountains on each side were
from 3000 to 6000 or 8000 feet high, with rounded outlines
and steep bare flanks. The general colour of the rock was
dullish purple, and the stratification very distinct. If the
scenery was not beautiful, it was remarkable and grand. We
met during the day several herds of cattle, which men were
driving down from the higher valleys in the Cordillera. This
sign of the approaching winter hurried our steps, more than
was convenient for geologizing. The house where we slept
was situated at the foot of a mountain, on the summit of
which are the mines of S. Pedro de Nolasko. Sir F. Head
marvels how mines have been discovered in such extraordi-
nary situations, as the bleak summit of the mountain of S.
Pedro de Nolasko. In the first place, metallic veins in this
country are generally harder than the surrounding strata:
hence, during the gradual wear of the hills, they project
above the surface of the ground. Secondly, almost every
labourer, especially in the northern parts of Chile, under-

THE VOYAGE OF THE BEAGLE 337

stands something about the appearance of ores. In the great
mining provinces of Coquimbo and Copiapo, firewood is very
scarce, and men search for it over every hill and dale; and
by this means nearly all the richest mines have there been
discovered. Chanuncillo, from which silver to the value of
many hundred thousand pounds has been raised in the course
of a few years, was discovered by a man who threw a stone
at his loaded donkey, and thinking that it was very heavy, he
picked it up, and found it full of pure silver: the vein oc-
curred at no great distance, standing up like a wedge of
metal. The miners, also, taking a crowbar with them, often
wander on Sundays over the mountains. In this south part
of Chile, the men who drive cattle into the Cordillera, and
who frequent every ravine where there is a little pasture, are
the usual discoverers.

20th. — As we ascended the valley, the vegetation, with
the exception of a few pretty alpine flowers, became exceed-
ingly scanty; and of quadrupeds, birds, or insects, scarcely
one could be seen. The lofty mountains, their summits
marked with a few patches of snow, stood well separated
from each other, the valleys being filled up with an immense
thickness of stratified alluvium. The features in the scenery
of the Andes which struck me most, as contrasted with the
other mountain chains with which I am acquainted, were, —
the flat fringes sometimes expanding into narrow plains on
each side of the valleys, — the bright colours, chiefly red and
purple, of the utterly bare and precipitous hills of porphyry,
the grand c.nd continuous wall-like dykes, — the plainly-
divided strata which, where nearly vertical, formed the pic-
turesque and wild central pinnacles, but where less inclined,
composed the great massive mountains on the outskirts of the
range, — and lastly, the smooth conical piles of fine and
brightly coloured detritus, which sloped up at a high angle
from the base of the mountains, sometimes to a height of
more than 2000 feet.

I frequently observed, both in Tierra del Fuego and within
the Andes, that where the rock was covered during the greater
part of the year with snow, it was shivered in a very extraor-
dinary manner into small angular fragments. Scoresby1

has observed the same fact in Spitzbergen. The case
appears to me rather obscure: for that part of the mountain
which is protected by a mantle of snow, must be less subject
to repeated and great changes of temperature than any other
part. I have sometimes thought, that the earth and frag-
ments of stone on the surface, were perhaps less effectually
removed by slowly percolating snow-water* than by rain, and
therefore that the appearance of a quicker disintegration of
the solid rock under the snow, was deceptive. Whatever the
cause may be, the quantity of crumbling stone on the Cordil-
lera is very great. Occasionally in the spring, great masses
of this detritus slide down the mountains, and cover the
snow-drifts in the valleys, thus forming natural ice-houses.
We rode over one, the height of which was far below the
limit of perpetual snow.

As the evening drew to a close, we reached a singular
basin-like plain, called the Valle del Yeso. It was covered
by a little dry pasture, and we had the pleasant sight of a
herd of cattle amidst the surrounding rocky deserts. The
valley takes its name of Yeso from a great bed, I should think
at least 2000 feet thick, of white, and in some parts quite
pure, gypsum. We slept with a party of men, who were
employed in loading mules with this substance, which is used
in the manufacture of wine. We set out early in the morning
(2ist), and continued to follow the course of the river, which
had become very small, till we arrived at the foot of the ridge,
that separates the waters flowing into the Pacific and Atlantic
Oceans. The road, which as yet had been good with a steady
but very gradual ascent, now changed into a steep zigzag
track up the great range, dividing the republics of Chile
and Mendoza.

I will here give a very brief sketch of the geology of the
several parallel lines forming the Cordillera. Of these lines,
there are two considerably higher than the others; namely,
on the Chilian side, the Peuquenes ridge, which, where the
road crosses it, is 13,210 feet above the sea; and the Portillo

1 1 have heard it remarked in Shropshire that the water, when the Severn
is flooded from long-continued rain, is much more turbid than when it
proceeds from the snow melting in the Welsh mountains. D'Orbigny (torn.
i. p. 184), in explaining the cause of the various colours of the rivers in
South America, remarks that those with blue or clear water have their
source in the Cordillera, where the snow melts.

THE VOYAGE OF THE BEAGLE 339

ridge, on the Mendoza side, which is 14,305 feet. The lower
beds of the Peuquenes ridge, and of the several great lines
to the westward of it, are composed of a vast pile, many thou-
sand feet in thickness, of porphyries which have flowed as
submarine lavas, alternating with angular and rounded frag-
ments of the same rocks, thrown out of the submarine craters.
These alternating masses are covered in the central parts,
by a great thickness of red sandstone, conglomerate, and cal-
careous clay-slate, associated with, and passing into, pro-
digious beds of gypsum. In these upper beds shells are toler-
ably frequent; and they belong to about the period of the
lower chalk of Europe. It is an old story, but not the less
wonderful, to hear of shells which were once crawling on the
bottom of the sea, now standing nearly 14,000 feet above its
level. The lower beds in this great pile of strata, have been
dislocated, baked, crystallized and almost blended together,
through the agency of mountain masses of a peculiar white
soda-granitic rock.

The other main line, namely, that of the Portillo, is of a
totally different formation : it consists chiefly of grand bare
pinnacles of a red potash-granite, which low down on the
western flank are covered by a sandstone, converted by the
former heat into a quartz-rock. On the quartz, there rest
beds of a conglomerate several thousand feet in thickness,
which have been upheaved by the red granite, and dip at an
angle of 45° towards the Peuquenes line. I was astonished
to find that this conglomerate was partly composed of peb-
bles, derived from the rocks, with their fossil shells, of the
Peuquenes range; and partly of red potash-granite, like that
of the Portillo. Hence we must conclude, that both the Peu-
quenes and Portillo ranges were partially upheaved and ex-
posed to wear and tear, when the conglomerate was forming ;
but as the beds of the conglomerate have been thrown off at
an angle of 45° by the red Portillo granite (with the under-
lying sandstone baked by it), we may feel sure, that the
greater part of the injection and upheaval of the already
partially formed Portillo line, took place after the accumula-
tion of the conglomerate, and long after the elevation of the
Peuquenes ridge. So that the Portillo, the loftiest line in this
part of the Cordillera, is not so old as the less lofty line of

340 CHARLES DARWIN

the Peuquenes. Evidence derived from an inclined stream
of lava at the eastern base of the Portillo, might be adduced
to show, that it owes part of its great height to elevations of
a still later date. Looking to its earliest origin, the red gran-
ite seems to have been injected on an ancient pre-existing line
of white granite and mica-slate. In most parts, perhaps in
all parts, of the Cordillera, it may be concluded that each line
has been formed by repeated upheavals and injections; and
that the several parallel lines are of different ages. Only
thus can we gain time, at all sufficient to explain the truly
astonishing amount of denudation, which these great, though
comparatively with most other ranges recent, mountains have
suffered.

Finally, the shells in the Peuquenes or oldest ridge, prove,
as before remarked, that it has been upraised 14,000 feet
since a Secondary period, which in Europe we are accus-
tomed to consider as far from ancient ; but since these shells
lived in a moderately deep sea, it can be shown that the area
now occupied by the Cordillera, must have subsided several
thousand feet — in northern Chile as much as 6000 feet — so
as to have allowed that amount of submarine strata to have
been heaped on the bed on which the shells lived. The proof
is the same with that by which it was shown, that at a much
later period, since the tertiary shells of Patagonia lived,
there must have been there a subsidence of several hundred
feet, as well as an ensuing elevation. Daily it is forced home
on the mind of the geologist, that nothing, not even the wind
that blows, is so unstable as the level of the crust of this
earth.

I will make only one other geological remark: although
the Portillo chain is here higher than the Peuquenes, the
waters draining the intermediate valleys, have burst through
it. The same fact, on a grander scale, has been remarked in
the eastern and loftiest line of the Bolivian Cordillera,
through which the rivers pass: analogous facts have also
been observed in other quarters of the world. On the sup-
position of the subsequent and gradual elevation of the Por-
tillo line, this can be understood; for a chain of islets would
at first appear, and, as these were lifted up, the tides would be
always wearing deeper and broader channels between them.

THE VOYAGE OF THE BEAGLE 341

At the present day, even in the most retired Sounds on the
coast of Tierra del Fuego, the currents in the transverse
breaks which connect the longitudinal channels, are very
strong, so that in one transverse channel even a small vessel
under sail was whirled round and round.

About noon we began the tedious ascent of the Peuquenes
ridge, and then for the first time experienced some little
difficulty in our respiration. The mules would halt every fifty
yards, and after resting for a few seconds the poor willing
animals started of their own accord again. The short breath-
ing from the rarefied atmosphere is called by the Chilenos
" puna ;" and they have most ridiculous notions concerning
its origin. Some say " all the waters here have puna ;" others
that " where there is snow there is puna ;" — and this no
doubt is true. The only sensation I experienced was a slight
tightness across the head and chest, like that felt on leaving
a warm room and running quickly in frosty weather. There
was some imagination even in this; for upon finding fossil
shells on the highest ridge, I entirely forgot the puna in my
delight. Certainly the exertion of walking was extremely
great, and the respiration became deep and laborious: I am
told that in Potosi (about 13,000 feet above the sea) strangers
do not become thoroughly accustomed to the atmosphere for
an entire year. The inhabitants all recommend onions for
the puna; as this vegetable has sometimes been given in
Europe for pectoral complaints, it may possibly be of real
service: — for my part I found nothing so good as the fossil
shells !

When about half-way up we met a large party with sev-
enty loaded mules. It was interesting to hear the wild cries
of the muleteers, and to watch the long descending string
of the animals ; they appeared so diminutive, there being
nothing but the black mountains with which they could be
compared. When near the summit, the wind, as generally
happens, was impetuous and extremely cold. On each side of
the ridge, we had to pass over broad bands of perpetual
snow, which were now soon to be covered by a fresh layer.
When we reached the crest and looked backwards, a glorious
view was presented. The atmosphere resplendently clear;

342 CHARLES DARWIN

the sky an intense blue; the profound valleys; the wild
broken forms; the heaps of ruins, piled up during the lapse
of ages ; the bright-coloured rocks, contrasted with the quiet
mountains of snow; all these together produced a scene no
one could have imagined. Neither plant nor bird, excepting
a few condors wheeling around the higher pinnacles, dis-
tracted my attention from the inanimate mass. I felt glad
that I was alone: it was like watching a thunderstorm, or
hearing in full orchestra a chorus of the Messiah.

On several patches of the snow I found the Protococcus
nivalis, or red snow, so well known from the accounts of
Arctic navigators. My attention was called to it, by observ-
ing the footsteps of the mules stained a pale red, as if their
hoofs had been slightly bloody. I at first thought that it was
owing to dust blown from the surrounding mountains of red
porphyry; for from the magnifying power of the crystals
of snow, the groups of these microscopical plants appeared
like coarse particles. The snow was coloured only where it
had thawed very rapidly, or had been accidentally crushed.
A little rubbed on paper gave it a faint rose tinge mingled
with a little brick-red. I afterwards scraped some off the
paper, and found that it consisted of groups of little spheres
in colourless cases, each of the thousandth part of an inch in
diameter.

The wind on the crest of the Peuquenes, as just remarked,
is generally impetuous and very cold: it is said* to blow
steadily from the westward or Pacific side. As the observa-
tions have been chiefly made in summer, this wind must be
an upper and return current. The Peak of Teneriffe, with
a less elevation, and situated in lat. 28°, in like manner falls
within an upper return stream. At first it appears rather
surprising, that the trade-wind along the northern parts of
Chile and on the coast of Peru, should blow in so very south-
erly a direction as it does ; but when we reflect that the Cor-
dillera, running in a north and south line, intercepts, like a
great wall, the entire depth of the lower atmospheric current,
we can easily see that the trade-wind must be drawn north-
ward, following the line of mountains, towards the equatorial

author gives the heights of the Passes.

THE VOYAGE OF THE BEAGLE 343

regions, and thus lose part of that easterly movement which
it otherwise would have gained from the earth's rotation. At
Mendoza, on the eastern foot of the Andes, the climate is
said to be subject to long calms, and to frequent though false
appearances of gathering rain-storms: we may imagine that
the wind, which coming from the eastward is thus banked up
by the line of mountains, would become stagnant and irregu-
lar in its movements.

Having crossed the Peuquenes, we descended into a moun-
tainous country, intermediate between the two main ranges,
and then took up our quarters for the night. We were now
in the republic of Mendoza. The elevation was probably not
under 11,000 feet, and the vegetation in consequence exceed-
ingly scanty. The root of a small scrubby plant served as
fuel, but it made a miserable fire, and the wind was
piercingly cold. Being quite tired with my day's work, I
made up my bed as quickly as I could, and went to sleep.
About midnight I observed the sky became suddenly clouded :
I awakened the arriero to know if there was any danger of
bad weather ; but he said that without thunder and lightning
there was no risk of a heavy snow-storm. The peril is
imminent, and the difficulty of subsequent escape great, to
any one overtaken by bad weather between the two ranges.
A certain cave offers the only place of refuge: Mr. Cald-
cleugh, who crossed on this same day of the month, was
detained there for some time by a heavy fall of snow. Casu-
chas, or houses of refuge, have not been built in this pass
as in that of Uspallata, and, therefore, during the autumn,
the Portillo is little frequented. I may here remark that
within the main Cordillera rain never falls, for during the
summer the sky is cloudless, and in winter snow-storms alone
occur.

At the place where we slept water necessarily boiled, from
the diminished pressure of the atmosphere, at a lower tem-
perature than it does in a less lofty country; the case being
the converse of that of a Papin's digester. Hence the pota-
toes, after remaining for some hours in the boiling water,
were nearly as hard as ever. The pot was left on the fire
all night, and next morning it was boiled again, but yet the
potatoes were not cooked. I found out this, by overhearing

344 CHARLES DARWIN

my two companions discussing the cause; they had come
to the simple conclusion, " that the cursed pot [which was a
new one] did not choose to boil potatoes."

March 22nd. — After eating our potatoless breakfast, we
travelled across the intermediate tract to the foot of the
Portillo range. In the middle of summer cattle are brought
up here to graze ; but they had now all been removed : even
the greater number of the Guanacos had decamped, knowing
well that if overtaken here by a snow-storm, they would be
caught in a trap. We had a fine view of a mass of moun-
tains called Tupungato, the whole clothed with unbroken
snow, in the midst of which there was a blue patch, no
doubt a glacier ; — a circumstance of rare occurrence in these
mountains. Now commenced a heavy and long climb, simi-
lar to that of the Peuquenes. Bold conical hills of red
granite rose on each hand ; in the valleys there were several
broad fields of perpetual snow. These frozen masses, during
the process of thawing, had in some parts been converted
into pinnacles or columns,* which, as they were high and
close together, made it difficult for the cargo mules to pass.
On one of these columns of ice, a frozen horse was stick-
ing as on a pedestal, but with its hind legs straight up in
the air. The animal, I suppose, must have fallen with its
head downward into a hole, when the snow was continuous,
and afterwards the surrounding parts must have been
removed by the thaw.

When nearly on the crest of the Portillo, we were envel-
oped in a falling cloud of minute frozen spicula. This was
very unfortunate, as it continued the whole day, and quite
intercepted our view. The pass takes its name of Portillo,
from a narrow cleft or doorway on the highest ridge,
through which the road passes. From this point, on a clear
day, those vast plains which uninterruptedly extend to the
Atlantic Ocean can be seen. We descended to the upper

* This structure in frozen snow was long since observed by Scoresby in
the icebergs near Spitzbergen, and, lately, with more care, by Colonel
Jackson (Journ. of Geograph. Soc., vol. v. p. 12) on the Neva. Mr. Lyell
(Principles, vol. iv. p. 360) has compared the fissures by which the
columnar structure seems to be determined, to the joints that traverse
nearly all rocks, but which are best seen in the non-stratified masses. I
may observe, that in the case of the frozen snow, the columnar structure
must be owing to a " metamorphic " action, and not to a process during
deposition.

THE VOYAGE OF THE BEAGLE 345

limit of vegetation, and found good quarters for the night
under the shelter of some large fragments of rock. We met
here some passengers, who made anxious inquiries about the
state of the road. Shortly after it was dark the clouds sud-
denly cleared away, and the effect was quite magical. The
great mountains, bright with the full moon, seemed impend-
ing over us on all sides, as over a deep crevice: one morn-
ing, very early, I witnessed the same striking effect. As
soon as the clouds were dispersed it froze severely; but as
there was no wind, we slept very comfortably.

The increased brilliancy of the moon and stars at this
elevation, owing to the perfect transparency of the atmos-
phere, was very remarkable. Travelers having observed
the difficulty of judging heights and distances amidst lofty
mountains, have generally attributed it to the absence of
objects of comparison. It appears to me, that it is fully as
much owing to the transparency of the air confounding
objects at different distances, and likewise partly to the
novelty of an unusual degree of fatigue arising from a little
exertion, — habit being thus opposed to the evidence of the
senses. I am sure that this extreme clearness of the air
gives a peculiar character to the landscape, all objects
appearing to be brought nearly into one plane, as in a draw-
ing or panorama. The transparency is, I presume, owing to
the equable and high state of atmospheric dryness. This
dryness was shown by the manner in which woodwork
shrank (as I soon found by the trouble my geological ham-
mer gave me) ; by articles of food, such as bread and sugar,
becoming extremely hard; and by the preservation of the
skin and parts of the flesh of the beasts, which had perished
on the road. To the same cause we must attribute the singu-
lar facility with which electricity is excited. My flannel
waistcoat, when rubbed in the dark, appeared as if it had
been washed with phosphorus ; — every hair on a dog's back
crackled; — even the linen sheets, and leathern straps of the
saddle, when handled, emitted sparks.

March 2$rd. — The descent on the eastern side of the Cor-
dillera is much shorter or steeper than on the Pacific side;
in other words, the mountains rise more abruptly from the
plains than from the alpine country of Chile. A level and

946 CHARLES DARWIN

brilliantly white sea of clouds was stretched out beneath our
feet, shutting out the view of the equally level Pampas. We
soon entered the band of clouds, and did not again emerge
from it that day. About noon, finding pasture for the ani-
mals and bushes for firewood at Los Arenales, we stopped
for the night. This was near the uppermost limit of bushes,
and the elevation, I suppose, was between seven and eight
thousand feet.

I was much struck with the marked difference between
the vegetation of these eastern valleys and those on the
Chilian side: yet the climate, as well as the kind of soil, is
nearly the same, and the difference of longitude very trifling.
The same remark holds good with the quadrupeds, and in
a lesser degree with the birds and insects. I may instance the
mice, of which I obtained thirteen species on the shores of
the Atlantic, and five on the Pacific, and not one of them
is identical. We must except all those species, which habitu-
ally or occasionally frequent elevated mountains; and cer-
tain birds, which range as far south as the Strait of Magel-
lan. This fact is in perfect accordance with the geological
history of the Andes; for these mountains have existed as
a great barrier since the present races of animals have
appeared ; and therefore, unless we suppose the same species
to have been created in two different places, we ought not to
expect any closer similarity between the organic beings on
the opposite sides of the Andes than on the opposite shores
of the ocean. In both cases, we must leave out of the ques-
tion those kinds which have been able to cross the barrier,
whether of solid rock or salt-water.6

A great number of the plants and animals were absolutely
the same as, or most closely allied to, those of Patagonia.
We here have the agouti, bizcacha, three species of arma-
dillo, the ostrich, certain kinds of partridges and other birds,
none of which are ever seen in Chile, but are the character-
istic animals of the desert plains of Patagonia. We have
likewise many of the same (to the eyes of a person who is

5 This is merely an illustration of the admirable laws, first laid down
by Mr. Lyell, on the geographical distribution of animals, as influenced
by geological changes. The whole reasoning, of course, is founded on the
assumption of the immutability of species; otherwise the difference in the
species in the two regions might be considered as superinduced during a
length of time.

THE VOYAGE OF THE BEAGLE 347

not a botanist) thorny stunted bushes, withered grass, and
dwarf plants. Even the black slowly crawling beetles are
closely similar, and some, I believe, on rigorous examination,
absolutely identical. It had always been to me a subject of
regret, that we were unavoidably compelled to give up the
ascent of the S. Cruz river before reaching the mountains:
I always had a latent hope of meeting with some great
change in the features of the country; but I now feel sure,
that it would only have been following the plains of Pata-
gonia up a mountainous ascent.

March s^th. — Early in the morning I climbed up a moun-
tain on one side of the valley, and enjoyed a far extended
view over the Pampas. This was a spectacle to which I had
always looked forward with interest, but I was disappointed:
at the first glance it much resembled a distant view of the
ocean, but in the northern parts many irregularities were
soon distinguishable. The most striking feature consisted
in the rivers, which, facing the rising sun, glittered like
silver threads, till lost in the immensity of the distance. At
midday we descended the valley, and reached a hovel, where
an officer and three soldiers were posted to examine pass-
ports. • One of these men was a thoroughbred Pampas
Indian: he was kept much for the same purpose as a blood-
hound, to track out any person who might pass by secretly,
either on foot or horseback. Some years ago, a passenger
endeavoured to escape detection, by making a long circuit
over a neighbouring mountain ; but this Indian, having by
chance crossed his track, followed it for the whole day over
dry and very stony hills, till at last he came on his prey
hidden in a gully. We here heard that the silvery clouds,
which we had admired from the bright region above, had
poured down torrents of rain. The valley from this point
gradually opened, and the hills became mere water-worn
hillocks compared to the giants behind : it then expanded
into a gently sloping plain of shingle, covered with low trees
and bushes. This talus, although appearing narrow, must be
nearly ten miles wide before it blends into the apparently
dead level Pampas. We passed the only house in this neigh-
bourhood, the Estancia of Chaquaio ; and at sunset we pulled
up in the first snug corner, and there bivouacked.

346

March 2$th. — I was reminded of the Pampas of Buenos
Ayres, by seeing the disk of the rising sun, intersected by an
horizon level as that of the ocean. During the night a heavy
dew fell, a circumstance which we did not experience within
the Cordillera. The road proceeded for some distance due
east across a low swamp; then meeting the dry plain, it
turned to the north towards Mendoza. The distance is two
very long days' journey. Our first day's journey was called
fourteen leagues to Estacado, and the second seventeen to
Luxan, near Mendoza. The whole distance is over a level
desert plain, with not more than two or three houses. The
sun was exceedingly powerful, and the ride devoid of all
interest. There is very little water in this " traversia," and
in our second day's journey we found only one little pool.
Little water flows from the mountains, and it soon becomes
absorbed by the dry and porous soil ; so that, although we
travelled at the distance of only ten or fifteen miles from
the outer range of the Cordillera, we did not cross a single
stream. In many parts the ground was incrusted with a
saline efflorescence ; hence we had the same salt-loving
plants which are common near Bahia Blanca. The land-
scape has a uniform character from the Strait of Magellan,
along the whole eastern coast of Patagonia, to the Rio Colo-
rado; and it appears that the same kind of country extends
inland from this river, in a sweeping line as far as San Luis,
and perhaps even further north. To the eastward of this
curved line lies the basin of the comparatively damp and
green plains of Buenos Ayres. The sterile plains of Men-
doza and Patagonia consist of a bed of shingle, worn smooth
and accumulated by the waves of the sea ; while the Pampas,
covered by thistles, clover, and grass, have been formed by
the ancient estuary mud of the Plata.

After our two days' tedious journey, it was refreshing to
see in the distance the rows of poplars and willows growing
round the village and river of Luxan. Shortly before we
arrived at this place, we observed to the south a ragged cloud
of dark reddish-brown colour. At first we thought that it
was smoke from some great fire on the plains; but we soon
found that it was a swarm of locusts. They were flying
northward; and with the aid of a light breeze, they overtook

THE VOYAGE OF THE BEAGLE 349

us at a rate of ten or fifteen miles an hour. The main body
filled the air from a height of twenty feet, to that, as it ap-
peared, of two or three thousand above the ground ; " and the
sound of their wings was as the sound of chariots of many
horses running to battle:" or rather, I should say, like a
strong breeze passing through the rigging of a ship. The
sky, seen through the advanced guard, appeared like a mezzo-
tinto engraving, but the main body was impervious to sight;
they were not, however, so thick together, but that they
could escape a stick waved backwards and forwards. When
they alighted, they were more numerous than the leaves in
the field, and the surface became reddish instead of being
green : the swarm having once alighted, the individuals flew
from side to side in all directions. Locusts are not an un-
common pest in this country : already during the season, sev-
eral smaller swarms had come up from the south, where, as
apparently in all other parts of the world, they are bred in
the deserts. The poor cottagers in vain attempted by light-
ing fires, by shouts, and by waving branches to avert the
attack. This species of locust closely resembles, and perhaps
is identical with, the famous Gryllus migratorius of the East.
We crossed the Luxan, which is a river of considerable
size, though its course towards the sea-coast is very imper-
fectly known: it is even doubtful whether, in passing over
the plains, it is not evaporated and lost. We slept in the
village of Luxan, which is a small place surrounded by gar-
dens, and forms the most southern cultivated district in the
Province of Mendoza; it is five leagues south of the capital.
At night I experienced an attack (for it deserves no less a
name) of the Benchuca, a species of Reduvius, the great
black bug of the Pampas. It is most disgusting to feel soft
wingless insects, about an inch long, crawling over one's
body. Before sucking they are quite thin, but afterwards
they become round and bloated with blood, and in this state
are easily crushed. One which I caught at Iquique, ( for they
are found in Chile and Peru,) was very empty. When placed
on a table, and though surrounded by people, if a finger was
presented, the bold insect would immediately protrude its
sucker, make a charge, and if allowed, draw blood. No pain
was caused by the wound. It was curious to watch its body

350 CHARLES DARWIN

during the act of sucking, as in less than ten minutes it
changed from being as flat as a wafer to a globular form.
This one feast, for which the benchuca was indebted to one
of the officers, kept it fat during four whole months; but,
after the first fortnight, it was quite ready to have another
suck.

March 2jth. — We rode on to Mendoza. The country was
beautifully cultivated, and resembled Chile. This neighbour-
hood is celebrated for its fruit; and certainly nothing could
appear more flourishing than the vineyards and the orchards
of figs, peaches, and olives. We bought water-melons nearly
twice as large as a man's head, most deliciously cool and
well-flavoured, for a halfpenny apiece; and for the value of
threepence, half a wheelbarrowful of peaches. The culti-
vated and enclosed part of this province is very small ; there
is little more than that which we passed through between
Luxan and the capital. The land, as in Chile, owes its fer-
tility entirely to artificial irrigation ; and it is really wonder-
ful to observe how extraordinarily productive a barren
traversia is thus rendered.

We stayed the ensuing day in Mendoza. The prosperity
of the place has much declined of late years. The inhabit-
ants say " it is good to live in, but very bad to grow rich in."
The lower orders have the lounging, reckless manners of the
Gauchos of the Pampas; and their dress, riding-gear, and
habits of life, are nearly the same. To my mind the town
had a stupid, forlorn aspect. Neither the boasted alameda,
nor the scenery, is at all comparable with that of Santiago ;
but to those who, coming from Buenos Ayres, have just
crossed the unvaried Pampas, the gardens and orchards must
appear delightful. Sir F. Head, speaking of the inhabitants,
says, " They eat their dinners, and it is so very hot, they go
to sleep — and could they do better ? " I quite agree with
Sir F. Head: the happy doom of the Mendozinos is to eat,
sleep and be idle.

March 2pth. — We set out on our return to Chile, by the
Uspallata pass situated north of Mendoza. We had to cross
a long and most sterile traversia of fifteen leagues. The
soil in parts was absolutely bare, in others covered by num-

THE VOYAGE OF THE BEAGLE 351

berless dwarf cacti, armed with formidable spines, and called
by the inhabitants " little lions." There were, also, a few
low bushes. Although the plain is nearly three thousand feet
above the sea, the sun was very powerful ; and the heat, as
well as the clouds of impalpable dust, rendered the travelling
extremely irksome. Our course during the day lay nearly
parallel to the Cordillera, but gradually approaching them.
Before sunset we entered one of the wide valleys, or rather
bays, which open on the plain: this soon narrowed into a
ravine, where a little higher up the house of Villa Vicencio
is situated. As we had ridden all day without a drop of
water, both our mules and selves were very thirsty, and we
looked out anxiously for the stream which flows down this
valley. It was curious to observe how gradually the water
made its appearance : on the plain the course was quite dry ;
by degrees it became a little damper; then puddles of water
appeared ; these soon became connected ; and at Villa Vicen-
cio there was a nice little rivulet.

30th. — The solitary hovel which bears the imposing name
of Villa Vicencio, has been mentioned by every traveller who
has crossed the Andes. I stayed here and at some neigh-
bouring mines during the two succeeding days. The geology
of the surrounding country is very curious. The Uspallata
range is separated from the main Cordillera by a long nar-
row plain or basin, like those so often mentioned in Chile,
but higher, being six thousand feet above the sea. This
range has nearly the same geographical position with respect
to the Cordillera, which the gigantic Portillo line has, but it
is of a totally different origin : it consists of various kinds of
submarine lava, alternating with volcanic sandstones and
other remarkable sedimentary deposits; the whole having a
very close resemblance to. some of the tertiary beds on the
shores of the Pacific. From this resemblance I expected to
find silicified wood, which is generally characteristic of those
formations. I was gratified in a very extraordinary manner.
In the central part of the range, at an elevation of about
seven thousand feet, I observed on a bare slope some snow-
white projecting columns. These were petrified trees, eleven
being silicified, and from thirty to forty converted into
coarsely-crystallized white calcareous spar. They were ab-

352 CHARLES DARWIN

ruptly broken off, the upright stumps projecting a few feet
above the ground. The trunks measured from three to five
feet each in circumference. They stood a little way apart
from each other, but the whole formed one group. Mr. Rob-
ert Brown has been kind enough to examine the wood: he
says it belongs to the fir tribe, partaking of the character
of the Araucarian family, but with some curious points of
affinity with the yew. The volcanic sandstone in which the
trees were embedded, and from the lower part of which they
must have sprung, had accumulated in successive thin layers
around their trunks; and the stone yet retained the impres-
sion of the bark.

It required little geological practice to interpret the mar-
vellous story which this scene at once unfolded; though I
confess I was at first so much astonished that I could
scarcely believe the plainest evidence. I saw the spot where
a cluster of fine trees once waved their branches on the
shores of the Atlantic, when that ocean (now driven back
700 miles) came to the foot of the Andes. I saw that they
had sprung from a volcanic soil which had been raised above
the level of the sea, and that subsequently this dry land,
with its upright trees, had been let down into the depths of
the ocean. In these depths, the formerly dry land was
covered by sedimentary beds, and these again by enormous
streams of submarine lava — one such mass attaining the
thickness of a thousand feet; and these deluges of molten
stone and aqueous deposits five times alternately had been
spread out. The ocean which received such thick masses,
must have been profoundly deep ; but again the subterranean
forces exerted themselves, and I now beheld the bed of
that ocean, forming a chain of mountains more than beven
thousand feet in height. Nor had those antagonistic forces
been dormant, which are always at work wearing down the
surface of the land; the great piles of strata had been in-
tersected by many wide valleys, and the trees now changed
into silex, were exposed projecting from the volcanic soil,
now changed into rock, whence formerly, in a green and
budding state, they had raised their lofty heads. Now,
all is utterly irreclaimable and desert; even the lichen can-
not adhere to the stony casts of former trees. Vast, and

THE VOYAGE OF THE BEAGLE 353

scarcely comprehensible as such changes must ever appear,
yet they have all occurred within a period, recent when
compared with the history of the Cordillera; and the Cor-
dillera itself is absolutely modern as compared with many
of the fossiliferous strata of Europe and America.

April ist. — We crossed the Upsallata range, and at night
slept at the custom-house — the only inhabited spot on the
plain. Shortly before leaving the mountains, there was a
very extraordinary view; red, purple, green, and quite white
sedimentary rocks, alternating with black lavas, were broken
up and thrown into all kinds of disorder by masses of por-
phyry of every shade of colour, from dark brown to the
brightest lilac. It was the first view I ever saw, which
really resembled those pretty sections which geologists make
of the inside of the earth.

The next day we crossed the plain, and followed the course
of the same great mountain stream which flows by Luxan.
Here it was a furious torrent, quite impassable, and appeared
larger than in the low country, as was the case with the rivu-
let of Villa Vicencio. On the evening of the succeeding day,
we reached the Rio de las Vacas, which is considered the
worst stream in the Cordillera to cross. As all these rivers
have a rapid and short course, and are formed by the melting
of the snow, the hour of the day makes a considerable differ-
ence in their volume. In the evening the stream is muddy
and full, but about daybreak it becomes clearer, and much
less impetuous. This we found to be the case with the Rio
Vacas, and in the morning we crossed it with little difficulty.

The scenery thus far was very uninteresting, compared
with that of the Portillo pass. Little can be seen beyond the
bare walls of the one grand flat-bottomed valley, which the
road follows up to the highest crest. The valley and
the huge rocky mountains are extremely barren: during the
two previous nights the poor mules had absolutely nothing
to eat, for excepting a few low resinous bushes, scarcely a
plant can be seen. In the course of this day we crossed some
of the worst passes in the Cordillera, but their danger has
been much exaggerated. I was told that if I attempted to
pass on foot, my head would turn giddy, and that there was
no room to dismount; but I did not see a place where any
VOL. xxix — L HC

354 CHARLES DARWIN

one might not have walked over backwards, or got off his
mule on either side. One of the bad passes, called las
Animas (the souls), I had crossed, and did not find out
till a day afterwards, that it was one of the awful dangers.
No doubt there are many parts in which, if the mule should
stumble, the rider would be hurled down a great precipice;
but of this there is little chance. I dare say, in the spring,
the " laderas," or roads, which each year are formed anew
across the piles of fallen detritus, are very bad ; but from
what I saw, I suspect the real danger is nothing. With
cargo-mules the case is rather different, for the loads pro-
ject so far, that the animals, occasionally running against
each other, or against a point of rock, lose their balance, and
are thrown down the precipices. In crossing the rivers
I can well believe that the difficulty may be very great: at
this season there was little trouble, but in the summer they
must be very hazardous. I can quite imagine, as Sir F.
Head describes, the different expressions of those who have
passed the gulf, and those who are passing. I never heard
of any man being drowned, but with loaded mules it fre-
quently happens. The arriero tells you to show your mule
the best line, and then allow her to cross as she likes: the
cargo-mule takes a bad line, and is often lost.

April 4th. — From the Rio de las Vacas to the Puente del
Incas, half a day's journey. As there was pasture for the
mules, and geology for me, we bivouacked here for the
night. When one hears of a natural Bridge, one pictures
to one's self some deep and narrow ravine, across which a
bold mass of rock has fallen; or a great arch hollowed out
like the vault of a cavern. Instead of this, the Incas
Bridge consists of a crust of stratified shingle cemented to-
gether by the deposits of the neighbouring hot springs. It
appears, as if the stream had scooped out a channel on one
side, leaving an overhanging ledge, which was met by earth
and stones falling down from the opposite cliff. Certainly
an oblique junction, as would happen in such a case, was
very distinct on one side. The Bridge of the Incas is by
no means worthy of the great monarchs whose name it
bears.

$th. — We had a long day's ride across the central ridge,

THE VOYAGE OF THE BEAGLE 355

from the Incas Bridge to the Ojos del Agua, which are situ-
ated near the lowest casucha on the Chilian side. These
casuchas are round little towers, with steps outside to reach
the floor, which is raised some feet above the ground on ac-
count of the snow-drifts. They are eight in number, and
under the Spanish government were kept during the winter
well stored with food and charcoal, and each courier had a
master-key. Now they only answer the purpose of caves, or
rather dungeons. Seated on some little eminence, they are
not, however, ill suited to the surrounding scene of desola-
tion. The zigzag ascent of the Cumbre, or the partition of
the waters, was very steep and tedious; its height, according
to Mr. Pentland, is 12,454 feet- The road did not pass over
any perpetual snow, although there were patches of it on
both hands. The wind on the summit was exceedingly cold,
but it was impossible not to stop for a few minutes to ad-
mire, again and again, the colour of the heavens, and the
brilliant transparency of the atmosphere. The scenery was
grand : to the westward there was a fine chaos of mountains,
divided by profound ravines. Some snow generally falls be-
fore this period of the season, and it has even happened that
the Cordillera have been finally closed by this time. But
we were most fortunate. The sky, by night and by day, was
cloudless, excepting a few round little masses of vapour, that
floated over the highest pinnacles. I have often seen these
islets in the sky, marking the position of the Cordillera,
when the far-distant mountains have been hidden beneath
the horizon.

April 6th. — In the morning we found some thief had
stolen one of our mules, and the bell of the madrina. We
therefore rode only two or three miles down the valley, and
stayed there the ensuing day in hopes of recovering the mule,
which the arriero thought had been hidden in some ravine.
The scenery in this part had assumed a Chilian character:
the lower sides of the mountains, dotted over with the pale
evergreen Quillay tree, and with the great chandelier-like
cactus, are certainly more to be admired than the bare east-
ern valleys; but I cannot quite agree with the admiration
expressed by some travellers. The extreme pleasure, I sus-
pect, is chiefly owing to the prospect of a good fire and of a

356 CHARLES DARWIN

good supper, after escaping from the cold regions above : and
I am sure I most heartily participated in these feelings.

8th. — We left the valley of the Aconcagua, by which we
had descended, and reached in the evening a cottage near the
Villa del St. Rosa. The fertility of the plain was delight-
ful : the autumn being advanced, the leaves of many of the
fruit-trees were falling; and of the labourers, — some were
busy in drying figs and peaches on the roofs of their cot-
tages, while others were gathering the grapes from the vine-
yards. It was a pretty scene ; but I missed that pensive still-
ness which makes the autumn in England indeed the evening
of the year. On the loth we reached Santiago, where I re-
ceived a very kind and hospitable reception from Mr. Cald-
cleugh. My excursion only cost me twenty-four days, and
never did I more deeply enjoy an equal space of time. A
few days afterwards I returned to Mr. Corfield's house at
Valparaiso.

APRIL 2?th. — I set out on a journey to Coquimbo, and
£\ thence through Guasco to Copiapo, where Captain
Fitz Roy kindly offered to pick me up in the Beagle.
The distance in a straight line along the shore northward is
only 420 miles; but my mode of travelling made it a very
long journey. I bought four horses and two mules, the
latter carrying the luggage on alternate days. The six
animals together only cost the value of twenty-five pounds
sterling, and at Copiapo I sold them again for twenty-three.
We travelled in the same independent manner as before,
cooking our own meals, and sleeping in the open air. As
we rode towards the Vino del Mar, I took a farewell view
of Valparaiso, and admired its picturesque appearance. For
geological purposes I made a detour from the high road
to the foot of the Bell of Quillota. We passed through an
alluvial district rich in gold, to the neighbourhood of Li-
mache, where we slept. Washing for gold supports the in-
habitants of numerous hovels, scattered along the sides of
each little rivulet; but, like all those whose gains are un-
certain, they are unthrifty in all their habits, and con-
sequently poor.

357

358 CHARLES DARWIN

28th. — In the afternoon we arrived at a cottage at the
foot of the Bell mountain. The inhabitants were freehold-
ers, which is not very usual in Chile. They supported them-
selves on the produce of a garden and a little field, but were
very poor. Capital is here so deficient, that the people are
obliged to sell their green corn while standing in the field,
in order to buy necessaries for the ensuing year. Wheat in
consequence was dearer in the very district of its production
than at Valparaiso, where the contractors live. The next
day we joined the main road to Coquimbo. At night there
was a very light shower of rain : this was the first drop that
had fallen since the heavy rain of September nth and I2th,
which detained me a prisoner at the Baths of Cauquenes.
The interval was seven and a half months ; but the rain this
year in Chile was rather later than usual. The distant Andes
were now covered by a thick mass of snow, and were a glo-
rious sight.

May 2nd. — The road continued to follow the coast, at no
great distance from the sea. The few trees and bushes which
are common in central Chile decreased rapidly in numbers,
and were replaced by a tall plant, something like a yucca in
appearance. The surface of the country, on a small scale,
was singularly broken and irregular; abrupt little peaks of
rock rising out of small plains or basins. The indented coast
and the bottom of the neighbouring sea, studded with break-
ers, would, if converted into dry land, present similar forms ;
and such a conversion without doubt has taken place in the
part over which we rode.

3rd. — Quilimari to Conchalee. The country became more
and more barren. In the valleys there was scarcely sufficient
water for any irrigation; and the intermediate land was
quite bare, not supporting even goats. In the spring, after
the winter showers, a thin pasture rapidly springs up, and
cattle are then driven down from the Cordillera to graze
for a short time. It is curious to observe how the seeds of
the grass and other plants seem to accommodate themselves,
as if by an acquired habit, to the quantity of rain which
falls upon different parts of this coast. One shower far
northward at Copiapo produces as great an effect on the
vegetation, as two at Guasco, and three or four in this

THE VOYAGE OF THE BEAGLE 359

district. At Valparaiso a winter so dry as greatly to injure
the pasture, would at Guasco produce the most unusual
abundance. Proceeding northward, the quantity of rain does
not appear to decrease in strict proportion to the latitude.
At Conchalee, which is only 67 miles north of Valparaiso,
rain is not expected till the end of May; whereas at Val-
paraiso some generally falls early in April : the annual quan-
tity is likewise small in proportion to the lateness of the
season at which it commences.

4th. — Finding the coast-road devoid of interest of any
kind, we turned inland towards the mining district and
valley of Illapel. This valley, like every other in Chile, is
level, broad, and very fertile: it is bordered on each side,
either by cliffs of stratified shingle, or by bare rocky moun-
tains. Above the straight line of the uppermost irrigating
ditch, all is brown as on a high road; while all below is of as
bright a green as verdigris, from the beds of alfalfa, a kind
of clover. We proceeded to Los Hornos, another mining
district, where the principal hill was drilled with holes, like
a great ants'-nest. The Chilian miners are a peculiar race
of men in their habits. Living for weeks together in the
most desolate spots, when they descend to the villages on
feast-days, there is no excess of extravagance into which
they do not run. They sometimes gain a considerable sum,
and then, like sailors with prize-money, they try how soon
they can contrive to squander it. They drink excessively,
buy quantities of clothes, and in a few days return penniless
to their miserable abodes, there to work harder than beasts
of burden. This thoughtlessness, as with sailors, is evidently
the result of a similar manner of life. Their daily food is
found them, and they acquire no habits of carefulness: more- •
over, temptation and the means of yielding to it are placed
in their power at the same time. On the other hand, in
Cornwall, and some other parts of England, where the sys-
tem of selling part of the vein is followed, the miners, from
being obliged to act and think for themselves, are a singu-
larly intelligent and well-conducted set of men.

The dress of the Chilian miner is peculiar and rather
picturesque. He wears a very long shirt of some dark-col-
oured baize, with a leathern apron ; the whole being fastened

360 CHARLES DARWIN

round his waist by a bright-coloured sash. His trousers are
very broad, and his small cap of scarlet cloth is made to fit
the head closely. We met a party of these miners in full
costume, carrying the body of one of their companions to be
buried. They marched at a very quick trot, four men sup-
porting the corpse. One set having run as hard as they
could for about two hundred yards, were relieved by four
others, who had previously dashed on ahead on horseback.
Thus they proceeded, encouraging each other by wild cries:
altogether the scene formed a most strange funeral.

We continued travelling northward, in a zigzag line;
sometimes stopping a day to geologize. The country was so
thinly inhabited, and the track so obscure, that we often had
difficulty in finding our way. On the I2th I stayed at some
mines. The ore in this case was not considered particularly
good, but from being abundant it was supposed the mine
would sell for about thirty or forty thousand dollars (that is,
6000 or 8000 pounds sterling) ; yet it had been bought by
one of the English Associations for an ounce of gold (3/.
8^.). The ore is yellow pyrites, which, as I have already re-
marked, before the arrival of the English, was not supposed
to contain a particle of copper. On a scale of profits nearly
as great as in the above instance, piles of cinders, abounding
with minute globules of metallic copper, were purchased;
yet with these advantages, the mining associations, as is well
known, contrived to lose immense sums of money. The folly
of the greater number of the commissioners and shareholders
amounted to infatuation; — a thousand pounds per annum
given in some cases to entertain the Chilian authorities;
libraries of well-bound geological books ; miners brought out
for particular metals, as tin, which are not found in Chile;
contracts to supply the miners with milk, in parts where
there are no cows; machinery, where it could not possibly
be used; and a hundred similar arrangements, bore witness
to our absurdity, and to this day afford amusement to the
natives. Yet there can be no doubt, that the same capital
well employed in these mines would have yielded an im-
mense return, a confidential man of business, a practical
miner and assayer, would have been all that was required.

Captain Head has described the wonderful load which

THE VOYAGE OF THE BEAGLE 361

the " Apires," truly beasts of burden, carry up from the
deepest mines. I confess I thought the account exaggerated ;
so that I was glad to take an opportunity of weighing one
of the loads, which I picked out by hazard. It required con-
siderable exertion on my part, when standing directly over
it, to lift it from the ground. The load was considered under
weight when found to be 197 pounds. The apire had car-
ried this up eighty perpendicular yards, — part of the way by
a steep passage, but the greater part up notched poles, placed
in a zigzag line up the shaft. According to the general
regulation, the apire is not allowed to halt for breath, ex-
cept the mine is six hundred feet deep. The average load is
considered as rather more than 200 pounds, and I have been
assured that one of 300 pounds (twenty-two stone and a half)
by way of a trial has been brought up from the deepest mine!
At this time the apires were bringing up the usual load
twelve times in the day; that is 2400 pounds from eighty
yards deep ; and they were employed in the intervals in break-
ing and picking ore.

These men, excepting from accidents, are healthy, and ap-
pear cheerful. Their bodies are not very muscular. They
rarely eat meat once a week, and never oftener, and then only
the hard dry charqui. Although with a knowledge that the
labour was voluntary, it was nevertheless quite revolting to
see the state in which they reached the mouth of the mine;
their bodies bent forward, leaning with their arms on the
steps, their legs bowed, their muscles quivering, the per-
spiration streaming from their faces over their breasts, their
nostrils distended, the corners of their mouth forcibly drawn
back, and the expulsion of their breath most laborious.
Each time they draw their breath, they utter an articulate
cry of " ay-ay," which ends in a sound rising from deep in
the chest, but shrill like the note of a fife. After staggering
to the pile of ore, they emptied the "carpacho;" in two or
three seconds recovering their breath, they wiped the sweat
from their brows, and apparently quite fresh descended the
mine again at a quick pace. This appears to me a wonderful
instance of the amount of labour which habit, for it can be
nothing else, will enable a man to endure.

In the evening, talking with the tnayor-domo of these

362 CHARLES DARWIN

mines about the number of foreigners now scattered over
the whole country, he told me that, though quite a young
man, he remembers when he was a boy at school at
Coquimbo, a holiday being given to see the captain of an
English ship, who was brought to the city to speak to the
governor. He believes that nothing would have induced
any boy in the school, himself included, to have gone close
to the Englishman; so deeply had they been impressed with
an idea of the heresy, contamination, and evil to be derived
from contact with such a person. To this day they relate
the atrocious actions of the bucaniers; «nd especially of
one man, who took away the figure of the Virgin Mary, and
returned the year after for that of St. Joseph, saying it
was a pity the lady should not have a husband. I heard
also of an old lady who, at a dinner at Coquimbo, remarked
how wonderfully strange it was that she should have lived
to dine in the same room with an Englishman; for she
remembered as a girl, that twice, at the mere cry of " Los
Ingleses," every soul, carrying what valuables they could,
had taken to the mountains.

iqth. — We reached Coquimbo, where we stayed a few
days. The town is remarkable for nothing but its extreme
quietness. It is said to contain from 6000 to 8000 inhabitants.
On the morning of the I7th it rained lightly, the first time
this year, for about five hours. The farmers, who plant
corn near the sea-coast where the atmosphere is most humid,
taking advantage of this shower, would break up the ground;
after a second they would put the seed in; and if a third
shower should fall, they would reap a good harvest in the
spring. It was interesting to watch the effect of this trifling
amount of moisture. Twelve hours afterwards the ground
appeared as dry as ever; yet after an interval of ten days,
all the hills were faintly tinged with green patches; the
grass being sparingly scattered in hair-like fibres a full
inch in length. Before this shower every part of the sur-
face was bare as on a high road.

In the evening, Captain Fitz Roy and myself were dining
with Mr. Edwards, an English resident well known for his
hospitality by all who have visited Coquimbo, when a sharp
earthquake happened. I heard the forecoming rumble, but

THE VOYAGE OF THE BEAGLE 363

from the screams of the ladies, the running of the servants,
and the rush of several of the gentlemen to the doorway, I
could not distinguish the motion. Some of the women after-
wards were crying with terror, and one gentleman said he
should not be able to sleep all night, or if he did, it would
only be to dream of falling houses. The father of this per-
son had lately lost all his property at Talcahuano, and he
himself had only just escaped a falling roof at Valparaiso,
in 1822. He mentioned a curious coincidence which then
happened: he was playing at cards, when a German, one of
the party, got up, and said he would never sit in a room in
these countries with the door shut, a? owing to his having
done so, he had nearly lost his life at Copiapo. Accordingly
he opened the door ; and no sooner had he done this, than he
cried out, " Here it comes again ! " and the famous shock
commenced. The whole party escaped. The danger in an
earthquake is not from the time lost in opening the door, but
from the chance of its becoming jammed by the movement
of the walls.

It is impossible to be much surprised at the fear which
natives and old residents, though some of them known to
be men of great command of mind, so generally experience
during earthquakes. I think, however, this excess of panic
may be partly attributed to a want of habit in governing
their fear, as it is not a feeling they are ashamed of. In-
deed, the natives do not like to see a person indifferent. I
heard of two Englishmen who, sleeping in the open air during
a smart shock, knowing that there was no danger, did not
rise. The natives cried out indignantly, " Look at those
heretics, they do not even get out of their beds ! "

I spent some days in examining the step-formed terraces
of shingle, first noticed by Captain B. Hall, and believed
by Mr. Lyell to have been formed by the sea, during the
gradual rising of the land. This certainly is the true
explanation, for I found numerous shells of existing species
on these terraces. Five narrow, gently sloping, fringe-like
terraces rise one behind the other, and where best developed
are formed of shingle : they front the bay, and sweep up both
sides of the valley. At Guasco, north of Coquimbo, the phe-

364 CHARLES DARWIN

nomenon is displayed on a much grander scale, so as to
strike with surprise even some of the inhabitants. The ter-
races are there much broader, and may be called plains; in
some parts there are six of them, but generally only five;
they run up the valley for thirty-seven miles from the coast.
These step-formed terraces or fringes closely resemble those
in the valley of S. Cruz, and, except in being on a smaller
scale, those great ones along the whole coast-line of Pata-
gonia. They have undoubtedly been formed by the denud-
ing power of the sea, during long periods of rest in the
gradual elevation of the continent.

Shells of many existing species not only lie on the sur-
face of the terraces at Coquimbo (to a height of 250 feet),
but are embedded in a friable calcareous rock, which in some
places is as much as between twenty and thirty feet in thick-
ness, but is of little extent. These modern beds rest on an
ancient tertiary formation containing shells, apparently all
extinct. Although I examined so many hundred miles of
coast on the Pacific, as well as Atlantic side of the conti-
nent, I found no regular strata containing sea-shells of
recent species, excepting at this place, and at a few points
northward on the road to Guasco. This fact appears to me
highly remarkable ; for the explanation generally given by
geologists, of the absence in any district of stratified fossil-
iferous deposits of a given period, namely, that the surface
then existed as dry land, is not here applicable; for we
know from the shells strewed on the surface and embedded
in loose sand or mould, that the land for thousands of miles
along both coasts has lately been submerged. The explana-
tion, no doubt, must be sought in the fact, that the whole
southern part of the continent has been for a long time
slowly rising; and therefore that all matter deposited along
shore in shallow water, must have been soon brought up
and slowly exposed to the wearing action of the sea-beach ;
and it is only in comparatively shallow water that the greater
number of marine organic beings can flourish, and in such
water it is obviously impossible that strata of any great
thickness can accumulate. To show the vast power of the
wearing action of sea-beaches, we need only appeal to the
great cliffs along the present coast of Patagonia, and to the

THE VOYAGE OF THE BEAGLE 365

escarpments or ancient sea-cliffs at different levels, one
above another, on that same line of coast.

The old underlying tertiary formation at Coquimbo,
appears to be of about the same age with several deposits
on the coast of Chile (of which that of Navedad is the
principal one), and with the great formation of Patagonia.
Both at Navedad and in Patagonia there is evidence, that
since the shells (a list of which has been seen by Professor
E. Forbes) there entombed were living, there has been a
subsidence of several hundred feet, as well as an ensuing
elevation. It may naturally be asked, how it comes that,
although no extensive fossiliferous deposits of the recent
period, nor of any period intermediate between it and the
ancient tertiary epoch, have been preserved on either side of
the continent, yet that at this ancient tertiary epoch, sedi-
mentary matter containing fossil remains, should have been
deposited and preserved at different points in north and
south lines, over a space of noo miles on the shores of the
Pacific, and of at least 1350 miles on the shores of the Atlan-
tic, and in an east and west line of 700 miles across the
widest part of the continent? I believe the explanation is
not difficult, and that it is perhaps applicable to nearly analo-
gous facts observed in other quarters of the world. Consid-
ering the enormous power of denudation which the sea
possesses, as shown by numberless facts, it is not probable
that a sedimentary deposit, when being upraised, could pass
through the ordeal of the beach, so as to be preserved in
sufficient masses to last to a distant period, without it were
originally of wide extent and of considerable thickness : now
it is impossible on a moderately shallow bottom, which
alone is favourable to most living creatures, that a thick
and widely extended covering of sediment could be spread
out, without the bottom sank down to receive the successive
layers. This seems to have actually taken place at about
the same period in southern Patagonia and Chile, though
these places are a thousand miles apart. Hence, if pro-
longed movements of approximately contemporaneous sub-
sidence are generally widely extensive, as I am strongly
inclined to believe from my examination of the Coral Reefs
of the great oceans — or if, confining our view to South

366 CHARLES DARWIN

America, the subsiding movements have been coextensive
with those of elevation, by which, within the same period
of existing shells, the shores of Peru, Chile, Tierra del
Fuego, Patagonia, and La Plata have been upraised — then
we can see that at the same time, at far distant points, cir-
cumstances would have been favourable to the formation of
fossiliferous deposits of wide extent and of considerable
thickness; and such deposits, consequently, would have a
good chance of resisting the wear and tear of successive
beach-lines, and of lasting to a future epoch.

May 2 1 st. — I set out in company with Don Jose Edwards
to the silver-mine of Arqueros, and thence up the valley of
Coquimbo. Passing through a mountainous country, we
reached by nightfall the mines belonging to Mr. Edwards.
I enjoyed my night's rest here from a reason which will not
be fully appreciated in England, namely, the absence of
fleas ! The rooms in Coquimbo swarm with them ; but they
will not live here at the height of only three or four thou-
sand feet: it can scarcely be the trifling diminution of tem-
perature, but some other cause which destroys these
troublesome insects at this place. The mines are now in a
bad state, though they formerly yielded about 2000 pounds
in weight of silver a year. It has been said that "a person
with a copper-mine will gain; with silver he may gain; but
with gold he is sure to lose." This is not true: all the large
Chilian fortunes have been made by mines of the more
precious metals. A short time since an English physician
returned to England from Copiapo, taking with him the
profits of one share of a silver-mine, which amounted to
about 24,000 pounds sterling. No doubt a copper-mine with
care is a sure game, whereas the other is gambling, or rather
taking a ticket in a lottery. The owners lose great quan-
tities of rich ores; for no precautions can prevent robberies.
I heard of a gentleman laying a bet with another, that one
of his men should rob him before his face. The ore when
brought out of the mine is broken into pieces, and the use-
less stone thrown on one side. A couple of the miners who
were thus employed, pitched, as if by accident, two fragments
away at the same moment, and then cried out for a joke

THE VOYAGE OF THE BEAGLE 367

" Let us see which rolls furthest." The owner, who was
standing by, bet a cigar with his friend on the race. The
miner by this means watched the very point amongst the
rubbish where the stone lay. In the evening he picked it
up and carried it to his master, showing him a rich mass of
silver-ore, and saying, " This was the stone on which you
won a cigar by its rolling so far."

May 2$rd. — We descended into the fertile valley of Co-
quimbo, and followed it till we reached an Hacienda belong-
ing to a relation of Don Jose, where we stayed the next day.
I then rode one day's journey further, to see what were
declared to be some petrified shells and beans, which latter
turned out to be small quartz pebbles. We passed through
several small villages; and the valley was beautifully culti-
vated, and the whole scenery very grand. We were here
near the main Cordillera, and the surrounding hills were
lofty. In all parts of northern Chile, fruit trees produce
much more abundantly at a considerable height near the
Andes than in the lower country. The figs and grapes of
this district are famous for their excellence, and are cul-
tivated to a great extent. This valley is, perhaps, the most
productive one north of Quillota. I believe it contains,
including Coquimbo, 25,000 inhabitants. The next day I
returned to the Hacienda, and thence, together with Don
Jose, to Coquimbo.

June 2nd. — We set out for the valley of Guasco, following
the coast-road, which was considered rather less desert than
the other. Our first day's ride was to a solitary house, called
Yerba Buena, where there was pasture for our horses. The
shower mentioned as having fallen, a fortnight ago, only
reached about half-way to Guasco; we had, therefore, in the
first part of our journey a most faint tinge of green, which
soon faded quite away. Even where brightest, it was scarcely
sufficient to remind one of the fresh turf and budding
flowers of the spring of other countries. While travelling
through these deserts one feels like a prisoner shut up in
a gloomy court, who longs to see something green and to
smell a moist atmosphere.

June jrd. — Yerba Buena to Carizal. During the first part
of the day we crossed a mountainous rocky desert, and after-

368 CHARLES DARWIN

wards a long deep sandy plain, strewed with broken sea-
shells. There was very little water, and that little saline :
the whole country, from the coast to the Cordillera, is an un-
inhabited desert. I saw traces only of one living animal in
abundance, namely, the shells of a Bulimus, which were
collected together in extraordinary numbers on the driest
spots. In the spring one humble little plant sends out a few
leaves, and on these the snails feed. As they are seen only
very early in the morning, when the ground is slightly damp
with dew, the Guascos believe that they are bred from it. I
have observed in other places that extremely dry and sterile
districts, where the soil is calcareous, are extraordinarily
favourable to land-shells. At Carizal there were a few cot-
tages, some brackish water, and a trace of cultivation : but it
was with difficulty that we purchased a little corn and straw
for our horses.

4th. — Carizal to Sauce. We continued to ride over desert
plains, tenanted by large herds of guanaco. We crossed also
the valley of Chaneral; which, although the most fertile one
between Guasco and Coquimbo, is very narrow, and produces
so little pasture, that we could not purchase any for our
horses. At Sauce we found a very civil old gentleman, super-
intendent of a copper-smelting furnace. As an especial
favour, he allowed me to purchase at a high price an armful
of dirty straw, which was all the poor horses had for supper
after their long day's journey. Few smelting- furnaces are
now at work in any part of Chile ; it is found more profitable,
on account of the extreme scarcity of firewood, and from
the Chilian method of reduction being so unskilful, to ship the
ore for Swansea. The next day we crossed some mountains
to Freyrina, in the valley of Guasco. During each day's ride
further northward, the vegetation became more and more
scanty; even the great chandelier-like cactus was here re-
placed by a different and much smaller species. During the
winter months, both in northern Chile and in Peru, a uniform
bank of clouds hangs, at no great height, over the Pacific.
From the mountains we had a very striking view of this
white and brilliant aerial-field, which sent arms up the valleys,
leaving islands and promontories in the same manner, as the
sea does in the Chonos archipelago and in Tierra del Fuego.

THE VOYAGE OF THE BEAGLE 369

We stayed two days at Freyrina. In the valley of Guasco
there are four small towns. At the mouth there is the port, a
spot entirely desert, and without any water in the immediate
neighbourhood. Five leagues higher up stands Freyrina, a
long straggling village, with decent whitewashed houses.
Again, ten leagues further up Ballenar is situated, and above
this Guasco Alto, a horticultural village, famous for its dried
fruit. On a clear day the view up the valley is very fine ; the
straight opening terminates in the far-distant snowy Cordil-
lera; on each side an infinity of crossing-lines are blended
together in a beautiful haze. The foreground is singular
from the number of parallel and step- formed terraces; and
the included strip of green valley, with its willow-bushes, is
contrasted on both hands with the naked hills. That the sur-
rounding country was most barren will be readily believed,
when it is known that a shower of rain had not fallen during
the last thirteen months. The inhabitants heard with the
greatest envy of the rain at Coquimbo; from the appearance
of the sky they had hopes of equally good fortune, which, a
fortnight afterwards, were realized. I was at Copiapo at the
time; and there the people, with equal envy, talked of the
abundant rain at Guasco. After two or three very dry years,
perhaps with not more than one shower during the whole
time, a rainy year generally follows ; and this does more harm
than even the drought. The rivers swell, and cover with
gravel and sand the narrow strips of ground, which alone are
fit for cultivation. The floods also injure the irrigating
ditches. Great devastation had thus been caused three years
ago.

June 8th. — We rode on to Ballenar, which takes its name
from Ballenagh in Ireland, the birthplace of the family of
O'Higgins, who, under the Spanish government, were presi-
dents and generals in Chile. As the rocky mountains on each
hand were concealed by clouds, the terrace-like plains gave
to the valley an appearance like that of Santa Cruz in Pata-
gonia. After spending one day at Ballenar I set out, on the
loth, for the upper part of the valley of Copiapo. We rode
all day over an uninteresting country. I am tired of repeat-
ing the epithets barren and sterile. These words, however,
as commonly used, are comparative; I have always applied

370 CHARLES DARWIN

them to the plains of Patagonia, which can boast of spiny
bushes and some tufts of grass ; and this is absolute fertility,
as compared with northern Chile. Here again, there are not
many spaces of two hundred yards square, where some little
bush, cactus or lichen, may not be discovered by careful
examination; and in the soil seeds lie dormant ready to
spring up during the first rainy winter. In Peru real deserts
occur over wide tracts of country. In the evening we
arrived at a valley, in which the bed of the streamlet was
damp: following it up, we came to tolerably good water.
During the night, the stream, from not being evaporated
and absorbed so quickly, flows a league lower down than
during the day. Sticks were plentiful for firewood, so that
it was a good place to bivouac for us; but for the poor ani-
mals there was not a mouthful to eat.

June nth. — We rode without stopping for twelve hours,
till we reached an old smelting-furnace, where there was
water and firewood ; but our horses again had nothing to eat,
being shut up in an old courtyard. The line of road was
hilly, and the distant views interesting, from the varied
colours of the bare mountains. It was almost a pity to see
the sun shining constantly over so useless a country; such
splendid weather ought to have brightened fields and pretty
gardens. The next day we reached the valley of Copiapo.
I was heartily glad of it; for the whole journey was a con-
tinued source of anxiety; it was most disagreeable to hear,
whilst eating our own suppers, our horses gnawing the posts
to which they were tied, and to have no means of relieving
their hunger. To all appearance, however, the animals
were quite fresh; and no one could have told that they had
eaten nothing for the last fifty-five hours.

I had a letter of introduction to Mr. Bingley, who received
me very kindly at the Hacienda of Potrero Seco. This
estate is between twenty and thirty miles long, but very nar-
row, being generally only two fields wide, one on each side
the river. In some parts the estate is of no width, that is
to say, the land cannot be irrigated, and therefore is value-
less, like the surrounding rocky desert. The small quantity
of cultivated land in the whole line of valley, does not so
much depend on inequalities of level, and consequent unfit-

THE VOYAGE OF THE BEAGLE 371

ness for irrigation, as on the small supply of water. The
river this year was remarkably full : here, high up the valley,
it reached to the horse's belly, and was about fifteen yards
wide, and rapid ; lower down it becomes smaller and smaller,
and is generally quite lost, as happened during one period
of thirty years, so that not a drop entered the sea. The
inhabitants watch a storm over the Cordillera with great
interest; as one good fall of snow provides them with water
for the ensuing year. This is of infinitely more consequence
than rain in the lower country. Rain, as often as it falls,
which is about once in every two or three years, is a great
advantage, because the cattle and mules can for some time
afterwards find a little pasture in the mountains. But with-
out snow on the Andes, desolation extends throughout the
valley. It is on record that three times nearly all the inhab-
itants have been obliged to emigrate to the south. This year
there was plenty of water, and every man irrigated his
ground as much as he chose; but it has frequently been
necessary to post soldiers at the sluices, to see that each
estate took only its proper allowance during so many hours
in the week. The valley is said to contain 12,000 souls, but
its produce is sufficient only for three months in the year;
the rest of the supply being drawn from Valparaiso and the
south. Before the discovery of the famous silver-mines of
Chanuncillo, Copiapo was in a rapid state of decay ; but now
it is in a very thriving condition ; and the town, which was
completely overthrown by an earthquake, has been rebuilt.

The valley of Copiapo, forming a mere ribbon of green
in a desert, runs in a very southerly direction; so that it is
of considerable length to its source in the Cordillera. The
valleys of Guasco and Copiapo may both be considered as
long narrow islands, separated from the rest of Chile by
deserts of rock instead of by salt water. Northward of
these, there is one other very miserable valley, called Paposo,
which contains about two hundred souls; and then there
extends the real desert of Atacama — a barrier far worse
than the most turbulent ocean. After staying a few days at
Potrero Seco, I proceeded up the valley to the house of Don
Benito Cruz, to whom I had a letter of introduction. I found
him most hospitable; indeed it is impossible to bear too

372 CHARLES DARWIN

strong testimony to the kindness with which travellers are
received in almost every part of South America. The next
day I hired some mules to take me by the ravine of Jol-
quera into the central Cordillera. On the second night the
weather seemed to foretell a storm of snow or rain, and whilst
lying in our beds we felt a trifling shock of an earthquake.

The connection between earthquakes and the weather has
been often disputed : it appears to me to be a point of great
interest, which is little understood. Humboldt has remarked
in one part of the Personal Narrative,1 that it would be
difficult for any person who had long resided in New Anda-
lusia, or in Lower Peru, to deny that there exists some con-
nection between these phenomena: in another part, however,
he seems to think the connection fanciful. At Guayaquil,
it is said that a heavy shower in the dry season is invariably
followed by an earthquake. In Northern Chile, from the
extreme infrequency of rain, or even of weather foreboding
rain, the probability of accidental coincidences becomes very
small; yet the inhabitants are here most firmly convinced of
some connection between the state of the atmosphere and of
the trembling of the ground: I was much struck by this,
when mentioning to some people at Copiapo that there had
been a sharp shock at Coquimbo : they immediately cried out,
" How fortunate ! there will be plenty of pasture there this
year." To their minds an earthquake foretold rain, as surely
as rain foretold abundant pasture. Certainly it did so hap-
pen that on the very day of the earthquake, that shower of
rain fell, which I have described as in ten days' time pro-
ducing a thin sprinkling of grass. At other times rain has
followed earthquakes at a period of the year when it is a
far greater prodigy than the earthquake itself: this happened
after the shock of November, 1822, and again in 1829, at
Valparaiso; also after that of September, 1833, at Tacna.
A person must be somewhat habituated to the climate of
these countries to perceive the extreme improbability of rain
falling at such seasons, except as a consequence of some law

1 Vol. iv, p. n, and vol. ii. p. 217. For the remarks on Guayaquil, see
Silliman's Journ., vol. xxiv. jp. .384. For those on Tacna by Mr. Hamilton,
see Trans, of British Association, 1840. For those on Coseguina see Mr.
Caldcleugh in Phil. Trans., 1835. In the former edition I collected several
references on the coincidences between sudden falls in the barometer and
earthquakes; and between earthquakes and meteors.

THE VOYAGE OF THE BEAGLE 373

quite unconnected with the ordinary course of the weather.
In the cases of great volcanic eruptions, as that of Co-
seguina, where torrents of rain fell at a time of the year most
unusual for it, and " almost unprecedented in Central
America," it is not difficult to understand that the volumes
of vapour and clouds of ashes might have disturbed the
atmospheric equilibrium. Humboldt extends this view to
the case of earthquakes unaccompanied by eruptions; but I
can hardly conceive it possible, that the small quantity of
aeriform fluids which then escape from the fissured ground,
can produce such remarkable effects. There appears much
probability in the view first proposed by Mr. P. Scrope, that
when the barometer is low, and when rain might naturally
be expected to fall, the diminished pressure of the atmos-
phere over a wide extent of country, might well determine
the precise day on which the earth, already stretched to the
utmost by the subterranean forces, should yield, crack, and
consequently tremble. It is, however, doubtful how far this
idea will explain the circumstances of torrents of rain fall-
ing in the dry season during several days, after an earth-
quake unaccompanied by an eruption; such cases seem to
bespeak some more intimate connection between the atmos-
pheric and subterranean regions.

Finding little of interest in this part of the ravine, we
retraced our steps to the house of Don Benito, where I stayed
two days collecting fossil shells and wood. Great prostrate
silicified trunks of trees, embedded in a conglomerate, were
extraordinarily numerous. I measured one, which was fif-
teen feet in circumference: how surprising it is that every
atom of the woody matter in this great cylinder should have
been removed and replaced by silex so perfectly, that each
vessel and pore is preserved ! These trees flourished at about
the period of our lower chalk; they all belonged to the fir-
tribe. It was amusing to hear the inhabitants discussing the
nature of the fossil shells which I collected, almost in the
same terms as were used a century ago in Europe, — namely,
whether or not they had been thus " born by nature." My
geological examination of the country generally created a
good deal of surprise amongst the Chilenos : it was long
before they could be convinced that I was not hunting for

374 CHARLES DARWIN

mines. This was sometimes troublesome: I found the most
ready way of explaining my employment, was to ask them
how it was that they themselves were not curious concerning
earthquakes and volcanos? — why some springs were hot and
others cold? — why there were mountains in Chile, and not
a hill in La Plata? These bare questions at once satisfied
and silenced the greater number; some, however (like a few
in England who are a century behindhand), thought that all
such inquiries were useless and impious; and that it was
quite sufficient that God had thus made the mountains.

An order had recently been issued that all stray dogs
should be killed, and we saw many lying dead on the road. A
great number had lately gone mad, and several men had been
bitten and had died in consequence. On several occasions
hydrophobia has prevailed in this valley. It is remarkable
thus to find so strange and dreadful a disease, appearing
time after time in the same isolated spot. It has been
remarked that certain villages in England are in like manner
much more subject to this visitation than others. Dr. Una-
nue states that hydrophobia was first known in South
America in 1803: this statement is corroborated by Azara
and Ulloa having never heard of it in their time. Dr. Una-
nue says that it broke out in Central America, and slowly
travelled southward. It reached Arequipa in 1807; and it is
said that some men there, who had not been bitten, were
affected, as were some negroes, who had eaten a bullock
which had died of hydrophobia. At lea forty-two people thus
miserably perished. The disease came on between twelve
and ninety days after the bite; and in those cases where it
did come on, death ensued invariably within five days. After
1808, a long interval ensued without any cases. On inquiry,
I did not hear of hydrophobia in Van Diemen's Land, or in
Australia ; and Burchell says, that during the five years he
was at the Cape of Good Hope, he never heard of an instance
of it. Webster asserts that at the Azores hydrophobia has
never occurred ; and the same assertion has been made with
respect to Mauritius and St. Helena.* In so strange a disease

THE VOYAGE OF THE BEAGLE 375

some information might possibly be gained by considering
the circumstances under which it originates in distant cli-
mates ; for it is improbable that a dog already bitten, should
have been brought to these distant countries.

At night, a stranger arrived at the house of Don Benito,
and asked permission to sleep there. He said he had been
wandering about the mountains for seventeen days, having
lost his way. He started from Guasco, and being accustomed
to travelling in the Cordillera, did not expect any difficulty
in following the track to Copiapo; but he soon became
involved in a labyrinth of mountains, whence he could not
escape. Some of his mules had fallen over precipices, and he
had been in great distress. His chief difficulty arose from
not knowing where to find water in the lower country, so that
he was obliged to keep bordering the central ranges.

We returned down the valley, and on the 22nd reached
the town of Copiapo. The lower part of the valley is broad,
forming a fine plain like that of Quillota. The town covers
a considerable space of ground, each house possessing a gar-
den : but it is an uncomfortable place, and the dwellings are
poorly furnished. Every one seems bent on the one object
of making money, and then migrating as quickly as possible.
All the inhabitants are more or less directly concerned with
mines; and mines and ores are the sole subjects of conver-
sation. Necessaries of all sorts are extremely dear; as the
distance from the town to the port is eighteen leagues, and
the land carriage very expensive. A fowl costs five or six
shillings; meat is nearly as dear as in England; firewood,
or rather sticks, are brought on donkeys from a distance of
two and three days' journey within the Cordillera; and pas-
turage for animals is a shilling a day : all this for South
America is wonderfully exorbitant.

June 26th. — I hired a guide and eight mules to take me
into the Cordillera by a different line from my last excur-
sion. As the country was utterly desert, we took a cargo
and a half of barley mixed with chopped straw. About two
leagues above the town a broad valley called the " Despo-
blado," or uninhabited, branches off from that one by which
we had arrived. Although a valley of the grandest dimen-

376 CHARLES DARWIN

sions, and leading to a pass across the Cordillera, yet it is
completely dry, excepting perhaps for a few days during
some very rainy winter. The sides of the crumbling moun-
tains were furrowed by scarcely any ravines ; and the bottom
of the main valley, filled with shingle, was smooth and nearly
level. No considerable torrent could ever have flowed down
this bed of shingle; for if it had, a great cliff-bounded chan-
nel, as in all the southern valleys, would assuredly have been
formed. I feel little doubt that this valley, as well as those
mentioned by travellers in Peru, were left in the state we now
see them by the waves of the sea, as the land slowly rose. I
observed in one place, where the Despoblado was joined by a
ravine (which in almost any other chain would have been
called a grand valley), that its bed, though composed merely
of sand and gravel, was higher than that of its tributary.
A mere rivulet of water, in the course of an hour, would have
cut a channel for itself; but it was evident that ages had
passed away, and no such rivulet had drained this great tribu-
tary. It was curious to behold the machinery, if such a term
may be used, for the drainage, all, with the last trifling excep-
tion, perfect, yet without any signs of action. Every one
must have remarked how mud-banks, left by the retiring tide,
imitate in miniature a country with hill and dale; and here
we have the original model in rock, formed as the continent
rose during the secular retirement of the ocean, instead of
during the ebbing and flowing of the tides. If a shower of
rain falls on the mud-bank, when left dry, it deepens the
already-formed shallow lines of excavation ; and so it is with
the rain of successive centuries on the bank of rock and soil,
which we call a continent.

We rode on after it was dark, till we reached a side ravine
with a small well, called " Agua amarga." The water
deserved its name, for besides being saline it was most offen-
sively putrid and bitter ; so that we could not force ourselves
to drink either tea or mate. I suppose the distance from the
river of Copiapo to this spot was at least twenty-five or thirty
English miles; in the whole space there was not a single
drop of water, the country deserving the name of desert in
the strictest sense. Yet about half way we passed some old
Indian ruins near Punta Gorda: I noticed also in front of

THE VOYAGE OF THE BEAGLE 377

some of the valleys, which branch off from the Despoblado,
two piles of stones placed a little way apart, and directed so
as to point up the mouths of these small valleys. My com-
panions knew nothing about them, and only answered my
queries by their imperturbable " quien sabe ? "

I observed Indian ruins in several parts of the Cordillera:
the most perfect which I saw, were the Ruinas de Tambillos,
in the Uspallata Pass. Small square rooms were there hud-
dled together in separate groups : some of the doorways were
yet standing ; they were formed by a cross slab of stone only
about three feet high. Ulloa has remarked on the lowness of
the doors in the ancient Peruvian dwellings. These houses,
when perfect, must have been capable of containing a con-
siderable number of persons. Tradition says, that they were
used as halting-places for the Incas, when they crossed the
mountains. Traces of Indian habitations have been dis-
covered in many other parts, where it does not appear proba-
ble that they were used as mere resting-places, but yet where
the land is as utterly unfit for any kind of cultivation, as it is
near the Tambillos or at the Incas Bridge, or in the Portillo
Pass, at all which places I saw ruins. In the ravine of
Jajuel, near Aconcagua, where there is no pass, I heard of
remains of houses situated at a great height, where it is
extremely cold and sterile. At first I imagined that these
buildings had been places of refuge, built by the Indians on
the first arrival of the Spaniards; but I have since been
inclined to speculate on the probability of a small change of
climate.

In this northern part of Chile, within the Cordillera, old
Indian houses are said to be especially numerous : by digging
amongst the ruins, bits of woollen articles, instruments of
precious metals, and heads of Indian corn, are not unfre-
quently discovered: an arrow-head made of agate, and of
precisely the same form with those now used in Tierra del
Fuego, was given me. I am aware that the Peruvian Indians
now frequently inhabit most lofty and bleak situations; but
at Copiapo I was assured by men who had spent their lives in
travelling through the Andes, that there were very many
(muchisimas) buildings at heights so great as almost to bor-
der upon the perpetual snow, and in parts where there exist

378 CHARLES DARWIN

no passes, and where the land produces absolutely nothing,
and what is still more extraordinary, where there is no water.
Nevertheless it is the opinion of the people of the country
(although they are much puzzled by the circumstance), that,
from the appearance of the houses, the Indians must have
used them as places of residence. In this valley, at Punta
Gorda, the remains consisted of seven or eight square little
rooms, which were of a similar form with those at Tambillos,
but built chiefly of mud, which the present inhabitants can-
not, either here or, according to Ulloa, in Peru, imitate in
durability. They were situated in the most conspicuous and
defenceless position, at the bottom of the flat broad valley.
There was no water nearer than three or four leagues, and
that only in very small quantity, and bad : the soil was abso-
lutely sterile ; I looked in vain even for a lichen adhering to
the rocks. At the present day, with the advantage of beasts
of burden, a mine, unless it were very rich, could scarcely
be worked here with profit. Yet the Indians formerly chose
it as a place of residence ! If at the present time two or
three showers of rain were to fall annually, instead of one,
as now is the case during as many years, a small rill of water
would probably be formed in this great valley; and then, by
irrigation (which was formerly so well understood by the
Indians), the soil would easily be rendered sufficiently pro-
ductive to support a few families.

I have convincing proofs that this part of the continent of
South America has been elevated near the coast at least from
400 to 500, and in some parts from 1000 to 1300 feet, since
the epoch of existing shells; and further inland the rise pos-
sibly may have been greater. As the peculiarly arid character
of the climate is evidently a consequence of the height of the
Cordillera, we may feel almost sure that before the later ele-
vations, the atmosphere could not have been so completely
drained of its moisture as it now is ; and as the rise has been
gradual, so would have been the change in climate. On this
notion of a change of climate since the buildings were
inhabited, the ruins must be of extreme antiquity, but I do
not think their preservation under the Chilian climate any
great difficulty. We must also admit on this notion (and
this perhaps is a greater difficulty) that man has inhabited

THE VOYAGE OF THE BEAGLE 379

South America for an immensely long period, inasmuch as
any change of climate effected by the elevation of the land
must have been extremely gradual. At Valparaiso, within
the last 220 years, the rise has been somewhat less than 19
feet : at Lima a sea-beach has certainly been upheaved from
80 to 90 feet, within the Indo-human period: but such small
elevations could have had little power in deflecting the mois-
ture-bringing atmospheric currents. Dr. Lund, however,
found human skeletons in the caves of Brazil, the appearance
of which induced him to believe that the Indian race has
existed during a vast lapse of time in South America.

When at Lima, I conversed on these subjects* with Mr.
Gill, a civil engineer, who had seen much of the interior
country. He told me that a conjecture of a change of cli-
mate had sometimes crossed his mind; but that he thought
that the greater portion of land, now incapable of cultivation,
but covered with Indian ruins, had been reduced to this state
by the water-conduits, which the Indians formerly con-
structed on so wonderful a scale, having been injured by
neglect and by subterranean movements. I may here men-
tion, that the Peruvians actually carried their irrigating
streams in tunnels through hills of solid rock. Mr. Gill told
me, he had been employed professionally to examine one:
he found the passage low, narrow, crooked, and not of uni-
form breadth, but of very considerable length. Is it not
most wonderful that men should have attempted such opera-
tions, without the use of iron or gunpowder ? Mr. Gill also
mentioned to me a most interesting, and, as far as I am
aware, quite unparalleled case, of a subterranean disturbance
having changed the drainage of a country. Travelling from
Casma to Huaraz (not very far distant from Lima), he
found a plain covered with ruins and marks of ancient culti-
vation, but now quite barren. Near it was the dry course of
a considerable river, whence the water for irrigation had for-
merly been conducted. There was nothing in the appearance
of the water-course to indicate that the river had not flowed

s Temple, in his travels through Upper Peru, or Bolivia, in going from
Potosi to Oruro, says, " I saw many Indian villages or dwellings in ruins,
up even to the very tops of the mountains, attesting a former population
where now all is desolate." He makes similar remarks in another place;
but I cannot tell whether this desolation has been caused by a want of
population, or by an altered condition of the land.

there a few years previously ; in some parts, beds of sand and
gravel were spread out; in others, the solid rock had been
worn into a broad channel, which in one spot was about 40
yards in breadth and 8 feet deep. It is self-evident that a
person following up the course of a stream, will always
ascend at a greater or less inclination: Mr. Gill, therefore,
was much astonished, when walking up the bed of this
ancient river, to find himself suddenly going down hill. He
imagined that the downward slope had a fall of about 40 or
50 feet perpendicular. We here have unequivocal evidence
that a ridge had been uplifted right across the old bed of a
stream. From the moment the river-course was thus arched,
the water must necessarily have been thrown back, and a new
channel formed. From that moment, also, the neighbouring
plain must have lost its fertilizing stream, and become a
desert.

June 2?th. — We set out early in the morning, and by mid-
day reached the ravine of Paypote, where there is a tiny rill
of water, with a little vegetation, and even a few algarroba
trees, a kind of mimosa. From having fire-wood, a smelting-
furnace had formerly been built here: we found a solitary
man in charge of it, whose sole employment was hunting
guanacos. At night it froze sharply; but having plenty of
wood for our fire, we kept ourselves warm.

28th. — We continued gradually ascending, and the valley
now changed into a ravine. During the day we saw several
guanacos, and the track of the closely-allied species, the
Vicuna: this latter animal is pre-eminently alpine in its
habits; it seldom descends much below the limit of perpetual
snow, and therefore haunts even a more lofty and sterile
situation than the guanaco. The only other animal which we
saw in any number was a small fox: I suppose this animal
preys on the mice and other small rodents, which, as long as
there is the least vegetation, subsist in considerable numbers
in very desert places. In Patagonia, even on the borders of
the salinas, where a drop of fresh water can never be found,
excepting dew, these little animals swarm. Next to lizards,
mice appear to be able to support existence on the smallest
and driest portions of the earth — even on islets in the midst
of great oceans.

THE VOYAGE OF THE BEAGLE 381

The scene on all sides showed desolation, brightened and
made palpable by a clear, unclouded sky. For a time such
scenery is sublime, but this feeling cannot last, and then it
becomes uninteresting. We bivouacked at the foot of the
" primera linea," or the first line of the partition of waters.
The streams, however, on the east side do not flow to the
Atlantic, but into an elevated district, in the middle of which
there is a large saline, or salt lake ; thus forming a little Cas-
pian Sea at the height, perhaps, of ten thousand feet. Where
we slept, there were some considerable patches of snow, but
they do not remain throughout the year. The winds in these
lofty regions obey very regular laws: every day a fresh
breeze blows up the valley, and at night, an hour or two after
sunset, the air from the cold regions above descends as
through a funnel. This night it blew a gale of wind, and the
temperature must have been considerably below the freezing-
point, for water in a vessel soon became a block of ice. No
clothes seemed to oppose any obstacle to the air; I suffered
very much from the cold, so that I could not sleep, and in
the morning rose with my body quite dull and benumbed.

In the Cordillera further southward, people lose their lives
from snowstorms; here, it sometimes happens from another
cause. My guide, when a boy of fourteen years old, was
passing the Cordillera with a party in the month of May;
and while in the central parts, a furious gale of wind arose,
so that the men could hardly cling on their mules, and stones
were flying along the ground. The day was cloudless, and
not a speck of snow fell, but the temperature was low. It is
probable that the thermometer could not have stood very
many degrees below the freezing-point, but the effect on
their bodies, ill protected by clothing, must have been in pro-
portion to the rapidity of the current of cold air. The gale
lasted for more than a day; the men began to lose their
strength, and the mules would not move onwards. My guide's
brother tried to return, but he perished, and his body was
found two years afterwards, lying by the side of his mule
near the road, with the bridle still in his hand. Two other
men in the party lost their fingers and toes; and out of two
hundred mules and thirty cows, only fourteen mules escaped
alive. Many years ago the whole of a large party are sup-

382 CHARLES DARWIN

posed to have perished from a similar cause, but their bodies
to this day have never been discovered. The union of a
cloudless sky, low temperature, and a furious gale of wind,
must be, I should think, in all parts of the world an unusual
occurrence.

June zpth. — We gladly travelled down the valley to our
former night's lodging, and thence to near the Agua amarga.
On July ist we reached the valley of Copiapo. The smell of
the fresh clover was quite delightful, after the scentless air
of the dry, sterile Despoblado. Whilst staying in the town I
heard an account from several of the inhabitants, of a hill
in the neighbourhood which they called " El Bramador," — the
roarer or bellower. I did not at the time pay sufficient atten-
tion to the account ; but, as far as I understood, the hill was
covered by sand, and the noise was produced only when
people, by ascending it, put the sand in motion. The same
circumstances are described in detail on the authority of
Seetzen and Ehrenberg,4 as the cause of the sounds which
have been heard by many travellers on Mount Sinai near the
Red Sea. One person with whom I conversed had himself
heard the noise: he described it as very surprising; and he
distinctly stated that, although he could not understand how
it was caused, yet it was necessary to set the sand rolling
down the acclivity. A horse walking over dry coarse sand,
causes a peculiar chirping noise from the friction of the par-
ticles; a circumstance which I several times noticed on the
coast of Brazil.

Three days afterwards I heard of the Beagle's arrival at
the Port, distant eighteen leagues from the town. There is
very little land cultivated down the valley ; its wide expanse
supports a wretched wiry grass, which even the donkeys can
hardly eat. This poorness of the vegetation is owing to the
quantity of saline matter with which the soil is impregnated.
The Port consists of an assemblage of miserable little hovels,
situated at the foot of a sterile plain. At present, as the
river contains water enough to reach the sea, the inhabitants
enjoy the advantage of having fresh water within a mile and
a half. On the beach there were large piles of merchandise,

THE VOYAGE OF THE BEAGLE 383

and the little place had an air of activity. In the evening
I gave my adios, with a hearty good-will, to my companion
Mariano Gonzales, with whom I had ridden so many leagues
in Chile. The next morning the Beagle sailed for Iquique.

July 12th. — We anchored in the port of Iquique, in lat-
20° 12', on the coast of Peru. The town contains about a
thousand inhabitants, and stands on a little plain of sand at
the foot of a great wall of rock, 2000 feet in height, here
forming the coast. The whole is utterly desert. A light
shower of rain falls only once in very many years ; and the
ravines consequently are filled with detritus, and the moun-
tain-sides covered by piles of fine white sand, even to a height
of a thousand feet. During this season of the year a heavy
bank of clouds, stretched over the ocean, seldom rises above
the wall of rocks on the coast. The aspect of the place was
most gloomy; the little port, with its few vessels, and small
group of wretched houses, seemed overwhelmed and out of
all proportion with the rest of the scene.

The inhabitants live like persons on board a ship: every
necessary comes from a distance : water is brought in boats
from Pisagua, about forty miles northward, and is sold at
the rate of nine reals (43. 6d.) an eighteen-gallon cask: I
bought a wine-bottle full for threepence. In like manner
firewood, and of course every article of food, is imported.
Very few animals can be maintained in such a place : on the
ensuing morning I hired with difficulty, at the price of four
pounds sterling, two mules and a guide to take me to the
nitrate of soda works. These are at present the support of
Iquique. This salt was first exported in 1830: in one year an
amount in value of one hundred thousand pounds sterling,
was sent to France and England. It is principally used as a
manure and in the manufacture of nitric acid: owing to its
deliquescent property it will not serve for gunpowder. For-
merly there were two exceedingly rich silver-mines in this
neighbourhood, but their produce is now very small.

Our arrival in the offing caused some little apprehension.
Peru was in a state of anarchy; and each party having
demanded a contribution, the poor town of Iquique was in
tribulation, thinking the evil hour was come. The people
had also their domestic troubles; a short time before, three

384 CHARLES DARWIN

French carpenters had broken open, during the same night,
the two churches, and stolen all the plate : one of the robbers,
however, subsequently confessed, and the plate was recovered.
The convicts were sent to Arequipa, which though the capital
of this province, is two hundred leagues distant ; the govern-
ment there thought it a pity to punish such useful workmen,
who could make all sorts of furniture; and accordingly
liberated them. Things being in this state, the churches were
again broken open, but this time the plate was not recovered.
The inhabitants became dreadfully enraged, and declaring
that none but heretics would thus " eat God Almighty," pro-
ceeded to torture some Englishmen, with the intention of
afterwards shooting them. At last the authorities interfered,
and peace was established.

ijth. — In the morning I started for the saltpetre-works,
a distance of fourteen leagues. Having ascended the steep
coast-mountains by a zigzag sandy track, we soon came in
view of the mines of Guantajaya and St. Rosa. These two
small villages are placed at the very mouths of the mines;
and being perched up on hills, they had a still more unnatural
and desolate appearance than the town of Iquique. We did
not reach the saltpetre-works till after sunset, having ridden
all day across an undulating country, a complete and utter
desert. The road was strewed with the bones and dried skins
of many beasts of burden which had perished on it from
fatigue. Excepting the Vultur aura, which preys on the
carcasses, I saw neither bird, quadruped, reptile, nor insect.
On the coast-mountains, at the height of about 2000 feet,
where during this season the clouds generally hang, a very
few cacti were growing in the clefts of rock ; and the loose
sand was strewed over with a lichen, which lies on the sur-
face quite unattached. This plant belongs to the genus
Cladonia, and somewhat resembles the reindeer lichen. In
some parts it was in sufficient quantity to tinge the sand,
as seen from a distance, of a pale yellowish colour. Further
inland, during the whole ride of fourteen leagues, I saw only
one other vegetable production, and that was a most minute
yellow lichen, growing on the bones of the dead mules. This
was the first true desert which I had seen: the effect on me

THE VOYAGE OF THE BEAGLE 385

was not impressive; but I believe this was owing to my
having become gradually accustomed to such scenes, as I
rode northward from Valparaiso, through Coquimbo, to Co-
piapo. The appearance of the country was remarkable, from
being covered by a thick crust of common salt, and of a strat-
ified saliferous alluvium, which seems to have been deposited
as the land slowly rose above the level of the sea. The salt
is white, very hard, and compact: it occurs in water- worn
nodules projecting from the agglutinated sand, and is asso-
ciated with much gypsum. The appearance of this super-
ficial mass very closely resembled that of a country after
snow, before the last dirty patches are thawed. The existence
of this crust of a soluble substance over the whole face of
the country, shows how extraordinarily dry the climate must
have been for a long period.

At night I slept at the house of the owner of one of the
saltpetre mines. The country is here as unproductive as
near the coast ; but water, having rather a bitter and brackish
taste, can be procured by digging wells. The well at this
house was thirty-six yards deep: as scarcely any rain falls,
it is evident the water is not thus derived ; indeed if it were,
it could not fail to be as salt as brine, for the whole sur-
rounding country is incrusted with various saline substances.
We must therefore conclude that it percolates under ground
.from the Cordillera, though distant many leagues. In that
direction there are a few small villages, where the inhabit-
ants, having more water, are enabled to irrigate a little land,
and raise hay, on which the mules and asses, employed in
carrying the saltpetre, are fed. The nitrate of soda was now
selling at the ship's side at fourteen shillings per hundred
pounds: the chief expense is its transport to the sea-coast.
The mine consists of a hard stratum, between two and three
feet thick, of the nitrate mingled with a little of the sulphate
of soda and a good deal of common salt. It lies close beneath
the surface, and follows for a length of one hundred and
fifty miles the margin of a grand basin or plain; this, from
its outline, manifestly must once have been a lake, or more
probably an inland arm of the sea, as may be inferred from
the presence of iodic salts in the saline stratum. The surface
of the plain is 3300 feet above the Pacific.

ipth. — We anchored in the Bay of Callao, the seaport of
Lima, the capital of Peru. We stayed here six weeks, but
from the troubled state of public affairs, I saw very little of
me country. During our whole visit the climate was far
from being so delightful, as it is generally represented. A
dull heavy bank of clouds constantly hung over the land, so
that during the first sixteen days I had only one view of the
Cordillera behind Lima. These mountains, seen in stages,
one above the other, through openings in the clouds, had a
very grand appearance. It is almost become a proverb, that
rain never falls in the lower part of Peru. Yet this can
hardly be considered correct ; for during almost every day of
our visit there was a thick drizzling mist, which was sufficient
to make the streets muddy and one's clothes damp: this the
people are pleased to call Peruvian dew. That much rain
does not fall is very certain, for the houses are covered only
with flat roofs made of hardened mud ; and on the mole ship-
loads of wheat were piled up, being thus left for weeks to-
gether without any shelter.

I cannot say I liked the very little I saw of Peru: in
summer, however, it is said that the climate is much pleas-
anter. In all seasons, both inhabitants and foreigners suffer
from severe attacks of ague. This disease is common on the
whole coast of Peru, but is unknown in the interior. The
attacks of illness which arise from miasma never fail to ap-
pear most mysterious. So difficult is it to judge from the
aspect of a country, whether or not it is healthy, that if a
person had been told to choose within the tropics a situation
appearing favourable for health, very probably he would
have named this coast. The plain round the outskirts of
Callao is sparingly covered with a coarse grass, and in some
parts there are a few stagnant, though very small, pools of
water. The miasma, in all probability, arises from these:
for the town of Arica was similarly circumstanced, and its
healthiness was much improved by the d/ainage of some
little pools. Miasma is not always produced by a luxuriant
vegetation with an ardent climate; for many parts of Bra-
zil, even where there are marshes and a rank vegetation, are
much more healthy than this sterile coast of Peru. The
densest forests in a temperate climate, as in Chiloe, do not

THE VOYAGE OF THE BEAGLE 387

seem in the slightest degree to affect the healthy condition
of the atmosphere.

The island of St. Jago, at the Cape de Verds, offers an-
other strongly marked instance of a country, which any one
would have expected to find most healthy, being very much
the contrary. I have described the bare and open plains as
supporting, during a few weeks after the rainy season, a thin
vegetation, which directly withers away and dries up : at this
period the air appears to become quite poisonous; both na-
tives and foreigners often being affected with violent fevers.
On the other hand, the Galapagos Archipelago, in the Pa-
cific, with a similar soil, and periodically subject to the same
process of vegetation, is perfectly healthy. Humboldt has
observed, that, " under the torrid zone, the smallest marshes
are the most dangerous, being surrounded, as at Vera Cruz
and Carthagena, with an arid and sandy soil, which raises
the temperature of the ambient air."6 On the coast of Peru,
however, the temperature is not hot to any excessive degree ;
and perhaps in consequence, the intermittent fevers are not
of the most malignant order. In all unhealthy countries the
greatest risk is run by sleeping on-shore. Is this owing to
the state of the body during sleep, or to a greater abundance
of miasma at such times? It appears certain that those
who stay on board a vessel, though anchored at only a short
distance from the coast, generally suffer less than those
actually on shore. On the other hand, I have heard of one
remarkable case where a fever broke out among the crew of
a rnan-of-war some hundred miles off the coast of Africa,
and at the same time one of those fearful periods' of death
commenced at Sierra Leone.

No state in South America, since the declaration of inde-
pendence, has suffered more from anarchy than Peru. At
the time of our visit, there were four chiefs in arms con-
tending for supremacy in the government: if one succeeded
in becoming for a time very powerful, the others coalesced
against him; but no sooner were they victorious, than they

6 Political Essay on the Kingdom of New Spain, vol. iv. p. 199.

8 A similar interesting case is recorded in the Madras Medical Quart.
Tourn., 1839, p. 340. Dr. Ferguson, in his admirable Paper (see 9th vol. of
Edinburgh Royal Trans.), shows clearly that the poison is generated in
the drying process; and hence that dry hot countries are often the most
unhealthy.

388 CHARLES DARWIN

were again hostile to each other. The other day, at the An-
niversary of the Independence, high mass was performed, the
President partaking of the sacrament: during the Te Deum
laudamus, instead of each regiment displaying the Peruvian
flag, a black one with death's head was unfurled. Imagine
a government under which such a scene could be ordered, on
such an occasion, to be typical of their determination of
fighting to death ! This state of affairs happened at a time
very unfortunately for me, as I was precluded from taking
any excursions much beyond the limits of the town. The
barren island of St. Lorenzo, which forms the harbour, was
nearly the only place where one could walk securely. The
upper part, which is upwards of 1000 feet in height, during
this season of the year (winter), comes within the lower
limit of the clouds ; and in consequence, an abundant crypto-
gamic vegetation, and a few flowers cover the summit. On
the hills near Lima, at a height but little greater, the ground
is carpeted with moss, and beds of beautiful yellow lilies,
called Amancaes. This indicates a very much greater de-
gree of humidity, than at a corresponding height at Iquique.
Proceeding northward of Lima, the climate becomes damper,
till on the banks of the Guayaquil, nearly under the equator,
we find the most luxuriant forests. The change, however,
from the sterile coast of Peru to that fertile land is described
as taking place rather abruptly in the latitude of Cape Blan-
co, two degrees south of Guayaquil.

Callao is a filthy, ill-built, small seaport. The inhabitants,
both here and at Lima, present every imaginable shade of
mixture, between European, Negro, and Indian blood. They
appear a depraved, drunken set of people. The atmosphere
is loaded with foul smells, and that peculiar one, which may
be perceived in almost every town within the tropics, was
here very strong. The fortress, which withstood Lord Coch-
rane's long siege, has an imposing appearance. But the
President, during our stay, sold the brass guns, and pro-
ceeded to dismantle parts of it. The reason assigned was,
that he had not an officer to whom he could trust so im-
portant a charge. He himself had good reason for thinking
so, as he had obtained the presidentship by rebelling while
in charge of this same fortress. After we left South Amer-

THE VOYAGE OF THE BEAGLE 389

ica, he paid the penalty in the usual manner, by being con-
quered, taken prisoner, and shot.

Lima stands on a plain in a valley, formed during the
gradual retreat of the sea. It is seven miles from Callao,
and is elevated 500 feet above it; but from the slope being
very gradual, the road appears absolutely level ; so that when
at Lima it is difficult to believe one has ascended even one
hundred feet : Humboldt has remarked on this singularly de-
ceptive case. Steep, barren hills rise like islands from the
plain, which is divided, by straight mud-walls, into large
green fields. In these scarcely a tree grows excepting a few
willows, and an occasional clump of bananas and of oranges.
The city of Lima is now in a wretched state of decay: the
streets are nearly unpaved; and heaps of filth are piled up
in all directions, where the black gallinazos, tame as poultry,
pick up bits of carrion. The houses have generally an upper
story, built on account of the earthquakes, of plastered wood-
work ; but some of the old ones, which are now used by sev-
eral families, are immensely large, and would rival in suites
of apartments the most magnificent in any place. Lima, the
City of the Kings, must formerly have been a splendid town.
The extraordinary number of churches gives it, even at the
present day, a peculiar and striking character, especially
when viewed from a short distance.

One day I went out with some merchants to hunt in the
immediate vicinity of the city. Our sport was very poor;
but I had an opportunity of seeing the ruins of one of the
ancient Indian villages, with its mound like a natural hill in
the centre. The remains of houses, enclosures, irrigating
streams, and burial mounds, scattered over this plain, cannot
fail to give one a high idea of the condition and number of
the ancient population. When their earthenware, woollen
clothes, utensils of elegant forms cut out of the hardest rocks,
tools of copper, ornaments of precious stones, palaces, and
hydraulic works, are considered, it is impossible not to re-
spect the considerable advance made by them in the arts of
civilization. The burial mounds, called Huacas, are really
stupendous; although in some places they 'appear to be nat-
ural hills incased and modelled.

There is also another and very different class of. ruins,

390 CHARLES DARWIN

which possesses some interest, namely, those of old Callao.
overwhelmed by the great earthquake of 1746, and its ac-
companying wave. The destruction must have been more
complete even than at Talcahuano. Quantities of shingle
almost conceal the foundations of the walls, and vast masses
of brickwork appear to have been whirled about like pebbles
by the retiring waves. It has been stated that the land sub-
sided during this memorable shock: I could not discover any
proof of this; yet it seems far from improbable, for the
form of the coast must certainly have undergone some change
since the foundation of the old town; as no people in their
senses would willingly have chosen for their building place,
the narrow spit of shingle on which the ruins now stand.
Since our voyage, M. Tschudi has come to the conclusion,
by the comparison of old and modern maps, that the coast
both north and south of Lima has certainly subsided.

On the island of San Lorenzo, there are very satisfactory
proofs of elevation within the recent period; this of course
is not opposed to the belief, of a small sinking of the ground
having subsequently taken place. The side of this island
fronting the Bay of Callao, is worn into three obscure ter-
races, the lower one of which is covered by a bed a mile in
length, almost wholly composed of shells of eighteen species,
now living in the adjoining sea. The height of this bed is
eighty-five feet. Many of the shells are deeply corroded, and
have a much older and more decayed appearance than those
at the height of 500 or 600 feet on the coast of Chile. These
shells are associated with much common salt, a little sul-
phate of lime (both probably left by the evaporation of the
spray, as the land slowly rose), together with sulphate of
soda and muriate of lime. They rest on fragments of the
underlying sandstone, and are covered by a few inches thick
of detritus. The shells, higher up on this terrace, could be
traced scaling off in flakes, and falling into an impalpable
powder; and on an upper terrace, at the height of 170 feet,
and likewise at some considerably higher points, I found a
layer of saline powder of exactly similar appearance, and
lying in the same relative position. I have no doubt that this
upper layer originally existed as a bed of shells, like that on
the eighty-five-feet ledge ; but it does not now contain even a

THE VOYAGE OF THE BEAGLE 391

trace of organic structure. The powder has been analyzed
for me by Mr. T. Reeks; it consists of sulphates and muri-
ates both of lime and soda, with very little carbonate of
lime. It is known that common salt and carbonate of lime
left in a mass for some time together, partly decompose each
other; though this does not happen with small quantities in
solution. As the half-decomposed shells in the lower parts
are associated with much common salt, together with some
of the saline substances composing the upper saline layer,
and as these shells are corroded and decayed in a remarkable
manner, I strongly suspect that this double decomposition
has here taken place. The resultant salts, however, ought
to be carbonate of soda and muriate of lime; the latter is
present, but not the carbonate of soda. Hence I am led to
imagine that by some unexplained means, the carbonate of
soda becomes changed into the sulphate. It is obvious that
the saline layer could not have been preserved in any coun-
try in which abundant rain occasionally fell: on the other
hand, this very circumstance, which at first sight appears so
highly favourable to the long preservation of exposed shells,
has probably been the indirect means, through the common
salt not having been washed away, of their decomposition
and early decay.

I was much interested by finding on the terrace, at the
height of eighty-five feet, embedded amidst the shells and
much sea-drifted rubbish, some bits of cotton thread, plaited
rush, and the head of a stalk of Indian corn: I compared
these relics with similar ones taken out of the Huacas, or old
Peruvian tombs, and found them identical in appearance.
On the mainland in front of San Lorenzo, near Bellavista,
there is an extensive and level plain about a hundred feet
high, of which the lower part is formed of alternating layers
of sand and impure clay, together with some gravel, and the
surface, to the depth of from three to six feet, of a reddish
loam, containing a few scattered sea-shells and numerous
small fragments of coarse red earthenware, more abundant
at certain spots than at others. At first I was inclined to
believe that this superficial bed, from its wide extent and
smoothness, must have been deposited beneath the sea; but
I afterwards found in one spot, that it lay on an artificial

392 CHARLES DARWIN

floor of round stones. It seems, therefore, most probable
that at a period when the land stood at a lower level there
was a plain very similar to that now surrounding Callao,
which being protected by a shingle beach, is raised but very
little above the level of the sea. On this plain, with its un-
derlying red-clay beds, I imagine that the Indians manu-
factured their earthen vessels ; and that, during some violent
earthquake, the sea broke over the beach, and converted the
plain into a temporary lake, as happened round Callao in
1713 and 1746. The water would then have deposited mud,
containing fragments of pottery from the kilns, more abun-
dant at some spots than at others, and shells from the sea.
This bed, with fossil earthenware, stands at about the
same height with the shells on the lower terrace of San
Lorenzo, in which the cotton-thread and other relics were
embedded.

Hence we may safely conclude, that within the Indo-human
period there has been an elevation, as before alluded to, of
more than eighty-five feet; for some little elevation must
have been lost by the coast having subsided since the old
maps were engraved. At Valparaiso, although in the 220
years before our visit, the elevation cannot have exceeded
nineteen feet, yet subsequently to 1817, there has been a rise,
partly insensible and partly by a start during the shock of
1822, of ten or eleven feet. The antiquity of the Indo-human
race here, judging by the eighty-five feet rise of the land
since the relics were embedded, is the more remarkable, as on
the coast of Patagonia, when the land stood about the same
number of feet lower, the Macrauchenia was a living beast ;
but as the Patagonian coast is some way distant from the
Cordillera, the rising there may have been, slower than here.
At Bahia Blanca, the elevation has been only a few feet
since the numerous gigantic quadrupeds were there en-
tombed; and, according to the generally received opinion,
when these extinct animals were living, man did not exist.
But the rising of that part of the coast of Patagonia, is per-
haps no way connected with the Cordillera, but rather with
a line of old volcanic rocks in Banda Oriental, so that it
may have been infinitely slower than on the shores of Peru.
All these speculations, however, must be vague ; for who will

THE VOYAGE OF THE BEAGLE 393

pretend to say that there may not have been several periods
of subsidence, intercalated between the movements of ele-
vation; for we know that along the whole coast of Pata-
gonia, there have certainly been many and long pauses in
the upward action of the elevatory forces.

C^EPTEMBER ijth.— This archipelago consists of ten
i\ principal islands, of which five exceed the others in
size. They are situated under the Equator, and be-
tween five and six hundred miles westward of the coast of
America. They are all formed of volcanic rocks; a few
fragments of granite curiously glazed and altered by the
heat, can hardly be considered as an exception. Some of
the craters, surmounting the larger islands, are of immense
size, and they rise to a height of between three and four
thousand feet. Their flanks are studded by innumerable
smaller orifices. I scarcely hesitate to affirm, that there
must be in the whole archipelago at least two thousand
craters. These consist either of lava or scoriae, or of finely-
stratified, sandstone-like tuff. Most of the latter are beau-
tifully symmetrical; they owe their origin to eruptions of
volcanic mud without any lava: it is a remarkable circum-
stance that every one of the twenty-eight tuff-craters which
were examined, had their southern sides either much lower
than the other sides, or quite broken down and removed. As
all these craters apparently have been formed when standing
in the sea, and as the waves from the trade wind and the
swell from the open Pacific here unite their forces on the
southern coasts of all the islands, this singular uniformity

in the broken state of the craters, composed of the soft and
yielding tuff, is easily explained.

Considering that these islands are placed directly under
the equator, the climate is far from being excessively hot;
this seems chiefly caused by the singularly low temperature
of the surrounding water, brought here by the great south-

ern Polar current. Excepting during one short season, very
little rain falls, and even then it is irregular; but the clouds
generally hang low. Hence, whilst the lower parts of the
islands are very sterile, the upper parts, at a height of a
thousand feet and upwards, possess a damp climate and a
tolerably luxuriant vegetation. This is especially the case
on the windward sides of the islands, which first receive and
condense the moisture from the atmosphere.

In the morning (i7th) we landed on Chatham Island^
which, like the others, rises with a tame an*8~T5unded out-
line, broken here and there by scattered hillocks, the remains

396 CHARLES DARWIN

of former craters. Nothing could be less inviting than the
first appearance. A broken field of black basaltic lava,
thrown into the most rugged waves, and crossed by great
fissures, is everywhere covered by stunted, sun-burnt brush-
wood, which shows little signs of life. The dry and parched
surface, being heated by the noon-day sun, gave to the air
a close and sultry feeling, like that from a stove: we fancied
even that the bushes smelt unpleasantly. Although I dili-
gently tried to collect as many plants as possible, I suc-
ceeded in getting very few ; and such wretched-looking little
weeds would have better become an arctic than an equatorial
Flora. The brushwood appears, from a short distance, as
leafless as bur trees during winter; and it was some time
before I discovered that ^lotpnly almost every_4ilaiit-was
now in full leaf, but that the^greatcr iiumbeT'were in flower.
The commonest bush is one ot the1 'Kupnoroiaceae : an acacia
and a great odd-looking cactus are the only trees which
afford any shade. After the season of heavy rains, the isl-
ands are said to appear for a short time partially green. The
volcanic island of Fernando Noronha, placed in many re-
spects under nearly similar conditions, is the only other
country where I have seen a vegetation at all like this of
the Galapagos Islands.

The Beagle sailed round Chatham Island, and anchored
in several bays. One night I slept on shore on a part of the
island, where black truncated cones were extraordinarily
numerous : from one small eminence I counted sixty of
them, all surmounted by craters more or less perfect. The
greater number consisted merely of a ring of red scoriae
or slags, cemented together : and their height above the plain
of lava was not more than from fifty to a hundred feet ; none
had been very lately active. The entire surface of this part
of the island seems to have been permeated, like a sieve, by
the subterranean vapours: here and there the lava, whilst
soft, has been blown into great bubbles; and in other parts,
the tops of caverns similarly formed have fallen in, leaving
circular pits with steep sides. From the regular form of the
many craters, they gave to the country an artificial appear-
ance, which vividly reminded me of those parts of Stafford-
shire, where the great iron-foundries are most numerous.

THE VOYAGE OF THE BEAGLE 397

The day was glowing hot, and the scrambling over the rough
surface and through the intricate thickets, was very fatigu-
ing; but I was well repaid by the strange Cyclopean scene.
As I was walking along I met two large tortoises, each of
which must have weighed at least two hundred pounds : one
was eating a piece of cactus, and as I approached, it stared
at me and slowly walked away; the other gave a deep hiss,
and drew in its head. These huge reptiles, surrounded by
the black lava, the leafless shrubs, and large cacti, seemed to
my fancy like some antediluvian animals. The few dull-
coloured birds cared no more for me than they did for the
great tortoises.

2$rd. — The Beagle proceeded to Charles Island. This ar-
chipelago has long been frequented, first by the bucaniers,
and latterly by whalers, but it is only within the last six
years, that a small colony has been established here. The
inhabitants are between two and three hundred in number;
they are nearly all people of colour, who have been banished
for political crimes from the Republic of the Equator, of
which Quito is the capital. The settlement is placed about
four and a half miles inland, and at a height probably of a
thousand feet. In the first part of the road we passed
through leafless thickets, as in Chatham Island. Higher up,
the woods gradually became greener; and as soon as we
crossed the ridge of the island, we were cooled by a fine
southerly breeze, and our sight refreshed by a green and
thriving vegetation. In this upper region coarse grasses and
fej-ns. abound ; but there are no tree-ferns : I saw nowhere
any member of the palm family, which is the more singular,
as 360 miles northward, Cocos Island takes its name from
the number of cocoa-nuts. The houses are irregularly scat-
tered over a flat space of ground, which is cultivated with
sweet potatoes and bananas. It will not easily be imagined
how pleasant the sight of black mud was to us, after having
been so long accustomed to the parched soil of Peru and
northern Chile. The inhabitants, although complaining of
poverty, obtain, without much trouble, the means of sub-
sistence. In the woods there are many wild pigs and goats ;
but the staple article of animal food is supplied by the
tortoises. Their numbers have of course been greatly re-

398 CHARLES DARWIN

duced in this island, but the people yet count on two days'
hunting giving them food for the rest of the week. It is
said that formerly single vessels have taken away as many
as seven hundred, and that the ship's company of a frigate
some years since brought down in one day two hundred
tortoises to the beach.

September zpth. — We doubled the south-west extremity of
Albemarle Island, and the next day were nearly becalmed
between it and Narborough Island. Both are covered with
immense deluges of black naked lava, which have flowed
either over the rims of the great caldrons, like pitch over the
rim of a pot in which it has been boiled, or have burst forth
from smaller orifices on the flanks; in their descent they
have spread over miles of the sea-coast. On both of these
islands, eruptions are known to have taken place; and in
Albemarle, we saw a small jet of smoke curling from the
summit of one of the great craters. In the evening we an-
chored in Bank's Cove, in Albemarle Island. The next
morning I went out walking. To the south of the broken
tuff -crater, in which the Beagle was anchored, there was
another beautifully symmetrical one of an elliptic form; its
longer axis was a little less than a mile, and its depth about
500 feet. At its bottom there was a shallow lake, in the
middle of which a tiny crater formed an islet. The day was
overpoweringly hot, and the lake looked clear and blue: I
hurried down the cindery slope, and, choked with dust,
eagerly tasted the water — but, to my sorrow, I found it salt
as brine.

The rocks on the coast abounded with great black lizards,
between three and four feet long; and on the hills, an ugly
yellowish-brown species was equally common. We saw
many of this latter kind, some clumsily running out of the
way, and others shuffling into their burrows. I shall pres-
ently describe in more detail the habits of both these reptiles.
The whole of this northern part of Albemarle Island is
miserably sterile.

October 8th. — We arrived at James Island: this island, as
well as Charles Island, were long since thus named after our
kings of the Stuart line. Mr. Bynoe, myself, and our serv-
ants were left here for a week, with provisions and a tent,

THE VOYAGE OF THE BEAGLE 399

whilst the Beagle went for water. We found here a party
of Spaniards, who had been sent from Charles Island to dry
fish, and to salt tortoise-meat. About six miles inland, and
at the. height of nearly 2000 feet, a hovel had been built in
which two men lived, who were employed in catching tor-
toises, whilst the others were fishing on the coast. I paid
this party two visits, and slept there one night. As in the
other islands, the lower region was covered by nearly leafless
bushes, but the trees were here of a larger growth than else-
where, several being two feet and some even two feet nine
inches in diameter. The upper region being kept damp by
the clouds, supports a green and flourishing vegetation. So
damp was the ground, that there were large beds of a coarse
cyperus, in which great numbers of a very small water-rail
lived and bred. While staying in this upper region, we lived
entirely upon tortoise-meat: the breast-plate roasted (as the
Gauchos do came con cuero), with the flesh on it, is very
good; and the young tortoises make excellent soup; but
otherwise the meat to my taste is indifferent.

One day we accompanied a party of the Spaniards in
their whale-boat to a salina, or lake from which salt is pro-
cured. After landing, we had a very rough walk over a
rugged field of recent lava, which has almost surrounded a
tuff-crater, at the bottom of which the salt-lake lies. The
water is only three or four inches deep, and rests on a layer
of beautifully crystallized, white salt. The lake is quite cir-
cular, and is fringed with a border of bright green succulent
plants ; the almost precipitous walls of the crater are clothed
with wood, so that the scene was altogether both picturesque
and curious. A few years since, the sailors belonging to a
sealing- vessel murdered their captain in this quiet spot; and
we saw his skull lying among the bushes.

During the greater part of our stay of a week, the sky
was cloudless, and if the trade-wind failed for an hour, the
heat became very oppressive. On two days, the thermometer
within the tent stood for some hours at 93° ; but in the open
air, in the wind and sun, at only 85°. The sand was ex-
tremely hot; the thermometer placed in some of a brown
colour immediately rose to 137°, and how much above that
it would have risen, I do not know, for it was not gradu-

400 CHARLES DARWIN

ated any higher. The black sand felt much hotter, so that
even in thick boots it was quite disagreeable to walk over it.

The natural history of these islands is eminently curious,
and well deserves attention. Most of the organic productions
are aboriginal creations, found nowhere else; there is even
a difference between the inhabitants of the different islands;
yet all show a marked relationship with those of America,
though separated from that continent by an open space of
ocean, between 500 and 600 miles in width. The archipelago
is a little world within itself, or rather a satellite attached to
America, whence it has derived a few stray colonists, and
has received the general character of its indigenous produc-
tions. Considering the small size of the islands, we feel
the more astonished at the number of their aboriginal beings,
and at their confined range. Seeing every height crowned
with its crater, and the boundaries of most of the lava-
streams still distinct, we are led to believe that within a
period geologically recent the unbroken ocean was here
spread out. Hence, both in space and time, we seem to be
brought somewhat near to that great fact — that mystery of
mysteries — the first appearance of new beings on this earth.

Of terrestrial mammals, there is only jane,. which must be
considered as indigenous, namely, a mouse (Mus Galapa-
goensis), and this is confined, as far as I could: ascertain, to
Chatham Island, the most easterly island of the group. It
belongs, as I am informed by Mr. Waterhouse, to a division
of the family of mice characteristic of America. At James
Island, there is a rat sufficiently distinct from the common
kind to have been named and described by Mr. Waterhouse ;
but as it belongs to the old-world division of the family, and
as this island has been frequented by ships for the last hun-
dred and fifty years, I can hardly doubt that this rat is
merely a variety produced by the new and peculiar climate,
food, and soil, to which it has been subjected. Although no
one has a right to speculate without distinct facts, yet even
with respect to the Chatham Island mouse, it should be borne
in mind, that it may possibly be an American species im-
ported here ; for I have seen, in a most unfrequented part of
the Pampas, a native mouse living in the roof of a newly

THE VOYAGE OF THE BEAGLE 401

built hovel, and therefore its transportation in a vessel is
not improbable: analogous facts have been observed by Dr.
Richardson in North America.

Of land-birds I obtained twenty-six kinds, all peculiar to
the group and found nowhere else, with the exception of one
lark-like finch from North America (Dolichonyxoryzivorus),
which ranges on that continent as far north as 54°, and gen-
erally frequents marshes. The other twenty-five birds con-
sist, firstly, of a hawk, curiously intermediate in structure
between a buzzard and the American group of carrion-feed-
ing Polybori; and with these latter birds it agrees most
closely in every habit and even tone of voice. Secondly,
there are two owls, representing the short-eared and white
barn-owls of Europe. Thirdly, a wren, three tyrant-flycatch-
ers (two of them species of Pyrocephalus, one or both of
which would be ranked by some ornithologists as only varie-
ties), and a dove — all analogous to, but distinct from, Amer-
ican species. Fourthly, a swallow, which though differing
from the Progne purpurea of both Americas, only in being
rather duller colored, smaller, and slenderer, is considered
by Mr. Gould as specifically distinct. Fifthly, there are three
species of mocking thrush — a form highly characteristic of
America. The remaining land-birds form a most singular
group of finches, related to each other in the structure of
their beaks, short tails, form of body and plumage : there are
thirteen species, which Mr. Gould has divided into four sub-
groups. All these species are peculiar to this archipelago;
and so is the whole group, with the exception of one species
of the sub-group Cactornis, lately brought from Bow Island,
in the Low Archipelago. Of Cactornis, the two species may
be often seen climbing about the flowers of the great cactus-
trees; but all the other species of this group of finches,
mingled together in flocks, feed on the dry and sterile ground
of the lower districts. The males of all, or certainly of the
greater number, are jet black; and the females (with perhaps
one or two exceptions) are brown. Thp most curious fart is
the perfect gradation in the size of the beaks in the different
species of Geospiza, from one as large as that of a hawfinch
to that of a chaffinch, and (if Mr. Gould is right in includ-
ing his sub-group, Certhidea, in the main group) even to

402

CHARLES DARWIN

that of a warbler. The largest beak in the genus Geospiza
is shown in Fig. i, and the smallest in Fig. 3; but instead of
there being only one intermediate species, with a beak of
the size shown in Fig. 2, there are no less than six species
with insensibly graduated beaks. The beak of the sub-group
Certhidea, is shown in Fig. 4. The beak of Cactornis is

3. Geospiza parvula.

somewhat like that of a starling; and that of the fourth sub-
group, Camarhynchus, is slightly parrot-shaped. Seeing this
gradation and diversity of structure in one small, intimately
related group of birds, one might really fancy that from an
original paucity of birds in this archipelago, one species had
been taken and modified for different ends. In a like manner
it might be fancied that a bird originally a buzzard, had been
induced here to undertake the office of the carrion-feeding
Polybori of the American continent.

Of waders and water-birds I was able to get only eleven
kinds, and of these only three (including a rail confined to
the damp summits of the islands) are new species. Consid-
ering the wandering habits of the gulls, I was surprised to
find that the species inhabiting these islands is peculiar, but
allied to one from the southern parts of South America.

THE VOYAGE OF THE BEAGLE 403

The far greater peculiarity of the land-birds, namely, twenty-
five out of twenty-six, being new species, or at least new
races, compared with the waders and web-footed birds, is
in accordance with the greater range which these latter
orders have in all parts of the world. We shall hereafter
see this law of aquatic forms, whether marine or fresh-
water, being less peculiar at any given point of the earth's
surface than the terrestrial forms of the same classes,
strikingly illustrated in the shells, and in a lesser degree in
the insects of this archipelago.

Two of the waders are rather smaller than the same spe-
cies brought from other places : the swallow is also smaller,
though it is doubtful whether or not it is distinct from its
analogue. The two owls, the two tyrant-catchers (Pyro-
cephalus) and the dove, are also smaller than the analogous
but distinct species, to which they are most nearly related;
on the other hand, the gull is rather larger. The two owls,
the swallow, all three species of mocking-thrush, the dove
in its separate colours though not in its whole plumage, the
Tetanus, and the gull, are likewise duskier coloured than
their analogous species; and in the case of the mocking-
thrush and Totanus, than any other species of the two gen-
era. With the exception of a wren with a fine yellow breast,
and of a tyrant-flycatcher with a scarlet tuft and breast, none
of the birds are brilliantly coloured, as might have been ex-
pected in an equatorial district. Hence it would appear
probable, that the same causes which here make the im-
migrants of some peculiar species smaller, make most of the
peculiar Galapageian species also smaller, as well as very
generally more dusky coloured. All the plants have a
wretched, weedy appearance, and I did not see one beautiful
flower. The insects, again, are small-sized and dull-coloured,
and, as Mr. Waterhouse informs me, there is nothing in their
general appearance which would have led him to imagine
that they had come from under the equator.1 The birds,

1 The progress of research has shown that some of these birds, which were
then thought to be confined to the islands, occur on the American continent.
The eminent^ ornithologist, Mr. Sclater, informs me that this is the case
with the Strix punctatissima and Pyrocephalus nanus; and probably with
the Otus Galapagoensis and Zenaida Galapagoensis: so that the number of
endemic birds is reduced to twenty-three, or probably to twenty-one. Mr.
Sclater thinks that one or two of these endemic forms should be ranked
rather as varieties than species, which always seemed to me probable.

404 CHARLES DARWIN

plants, and insects have a desert character, and are not more
brilliantly coloured than those from southern Patagonia; we
may, therefore, conclude that the usual gaudy colouring of
the inter-tropical productions, is not related either to the
heat or light of those zones, but to some other cause, per-
haps to the conditions of existence being generally favour-
able to life.

We will now turn to the order of reptiles, which gives
the most striking character to the zoology of these islands.
The species are not numerous, but the numbers of individ-
uals of each species are extraordinarily great. There is one
small lizard belonging to a South American genus, and two
species (and probably more) of the Amblyrhynchus — a genus
confined to the Galapagos Islands. There is one snake which
is numerous ; it is identical, as I am informed by M. Bibron,
with the Psammophis Temminckii from Chile.* Of sea-
turtle I believe there are more than one species; and of tor-
toises there are, as we shall presently show, two or three
species or races. Of toads and frogs there are none: I was
surprised at this, considering how well suited for them the
temperate and damp upper woods appeared to be. It re-
called to my mind the remark made by Bory St. Vincent,*
namely, that none of this family are found on any of the vol-
canic islands in the great oceans. As far as I can ascertain
from various works, this seems to hold good throughout the
Pacific, and even in the large islands of the Sandwich archi-
pelago. Mauritius offers an apparent exception, where I
saw the Rana Mascariensis in abundance: this frog is said
now to inhabit the Seychelles, Madagascar, and Bourbon;
but on the other hand, Du Bois, in his voyage in 1669, states
that there were no reptiles in Bourbon except tortoises ; and
the Officier du Roi aserts that before 1768 it had been at-
tempted, without success, to introduce frogs into Mauritius
—I presume for the purpose of eating : hence it may be well

3 This is stated by Dr. Gunther (Zoolog. Soc., Jan 24th, 1859) to be a
peculiar species, not known to inhabit any other country.

3 Voyage aux Quatre lies d'Afrique. With respect to the Sandwich
Islands, see Tyerman and Bennett's Journal, vol. i. p. 434. For Mauritius,
see Voyage par un Officier, etc., part i. p. 170. There are no frogs in the
Canary Islands (Webb et Berthelot, Hist. Nat. des lies Canaries). I saw
none at St. Jago in the Cape de Verds. There are none at St. Helena.

THE VOYAGE OF THE BEAGLE 405

doubted whether this frog is an aboriginal of these islands.
The absence of the frog family in the oceanic islands is the
more remarkable, when contrasted with the case of lizards,
which swarm on most of the smallest islands. May this dif-
ference not be caused, by the greater facility with which the
eggs of lizards, protected by calcareous shells, might be
transported through salt-water, than could the slimy spawn
of frogs?

I will first describe the habits of the tortoise (Testudo
nigra, formerly called Indica), which has been so frequently
alluded to. These animals are found, I believe, on all the
islands of the archipelago; certainly on the greater number.
They frequent in preference the high damp parts, but they
likewise live in the lower and arid districts. I have already
shown, from the numbers which have been caught in a single
day, how very numerous they must be. Some grow to an
immense size: Mr. Lawson, an Englishman, and vice-gov-
ernor of the colony, told us that he had seen several so large,
that it required six or eight men to lift them from the
ground ; and that some had afforded as much as two hundred
pounds of meat. The old males are the largest, the females
rarely growing to so great a size: the male can readily be
distinguished from the female by the greater length of its
tail. The tortoises which live on those islands where there
is no water, or in the lower and arid parts of the others, feed
chiefly on the succulent cactus. Those which frequent the
higher and damp regions, eat the leaves of various trees, a
kind of berry (called guayavita) which is acid and austere,
and likewise a pale green filamentous lichen (Usneraplicata),
that hangs from the boughs of the trees.

The tortoise is very fond of water, drinking large quan-
tities, and wallowing in the mud. The larger islands alone
possess springs, and these are always situated towards the
central parts, and at a considerable height. The tortoises,
therefore, which frequent the lower districts, when thirsty,
are obliged to travel from a long distance. Hence broad and
well-beaten paths branch off in every direction from the
wells down to the sea-coast ; and the Spaniards by following
them up, first discovered the watering-places. When I landed
at Chatham Island, I could not imagine what animal travelled

406 CHARLES DARWIN

so methodically along well-chosen tracks. Near the springs
it was a curious spectacle to behold many of these huge
creatures, one set eagerly travelling onwards with out-
stretched necks, and another set returning, after having
drunk their fill. When the tortoise arrives at the spring,
quite regardless of any spectator, he buries his head in the
water above his eyes, and greedily swallows great mouthfuls,
at the rate of about ten in a minute. The inhabitants say
each animal stays three or four days in the neighbourhood
of the water, and then returns to the lower country; but
they differed respecting the frequency of these visits. The
animal probably regulates them according to the nature of
the food on which it has lived. It is, however, certain, that
tortoises can subsist even on these islands where there is no
other water than what falls during a few rainy days in the
year.

I believe it is well ascertained, that the bladder of the frog
acts as a reservoir for the moisture necessary to its exist-
ence : such seems to be the case with the tortoise. For some
time after a visit to the springs, their urinary bladders are
distended with fluid, which is said gradually to decrease in
volume, and to become less pure. The inhabitants, when
walking in the lower district, and overcome with thirst, often
take advantage of this circumstance, and drink the contents
of the bladder if full : in one I saw killed, the fluid was quite
limpid, and had only a very slightly bitter taste. The inhabit-
ants, however, always first drink the water in the pericar-
dium, which is described as being best.

The tortoises, when purposely moving towards any point,
travel by night and day, and arrive at their journey's end
much sooner than would be expected. The inhabitants, from
observing marked individuals, consider that they travel a
distance of about eight miles in two or three days. One large
tortoise, which I watched, walked at the rate of sixty yards
in ten minutes, that is 360 yards in the hour, or four miles a
day, — allowing a little time for it to eat on the road. During
the breeding season, when the male and female are together,
the male utters a hoarse roar or bellowing, which, it is said,
can be heard at the distance of more than a hundred yards.
The female never uses her voice, and the male only at these

THE VOYAGE OF THE BEAGLE 407

times; so that when the people hear this noise, they know
that the two are together. They were at this time (October)
laying their eggs. The female, where the soil is sandy, de-
posits them together, and covers them up with sand; but
where the ground is rocky she drops them indiscriminately
in any hole : Mr. Bynoe found seven placed in a fissure. The
egg is white and spherical ; one which I measured was seven
inches and three-eighths in circumference, and therefore
larger than a hen's egg. The young tortoises, as soon as they
are hatched, fall a prey in great numbers to the carrion-
feeding buzzard. The old ones seem generally to die from
accidents, as from falling down precipices : at least, several
of the inhabitants told me, that they never found one dead
without some evident cause.

The inhabitants believe that these animals are absolutely
deaf; certainly they do not overhear a person walking close
behind them. I was always amused when overtaking one of
these great monsters, as it was quietly pacing along, to see
how suddenly, the instant I passed, it would draw in its head
and legs, and uttering a deep hiss fall to the ground with a
heavy sound, as if struck dead. I frequently got on their
backs, and then giving a few raps on the hinder part of their
shells, they would rise up and walk away ; — but I found it
very difficult to keep my balance. The flesh of this animal is
largely employed, both fresh and salted; and a beautifully
clear oil is prepared from the fat. When a tortoise is caught,
the man makes a slit in the skin near its tail, so as to see
inside its body, whether the fat under the dorsal plate is
thick. If it is not, the animal is liberated and it is said to
recover soon from this strange operation. In order to secure
the tortoise, it is not sufficient to turn them like turtle, for
they are often able to get on their legs again.

There can be little doubt that this tortoise is an aboriginal
inhabitant of the Galapagoes ; for it is found on all, or nearly
all, the islands, even on some of the smaller ones where there
is no water; had it been an imported species, this would
hardly have been the case in a group which has been so little
h frequented. Moreover, the old Bucaniers found this tortoise
in greater numbers even than at present : Wood and Rogers
also, in 1708, say that it is the opinion of the Spaniards, that

408 CHARLES DARWIN

it is found nowhere else in this quarter of the world. It is
now widely distributed; but it may be questioned whether
it is in any other place an aboriginal. The bones of a tor-
toise at Mauritius, associated with those of the extinct Dodo,
have generally been considered as belonging to this tortoise ;
if this had been so, undoubtedly it must have been there
indigenous; but M. Bibron informs me that he believes that
it was distinct, as the species now living there certainly is.

The Amblyrhynchus, a remarkable genus of lizards, is con-
fined to this archipelago; there are two species, resembling

Amblyrhynchus cristatus. a, Tooth of, natural size, and likewise magnified.

each other in general form, one being terrestrial and the
other aquatic. This latter species (A. cristatus) was first
characterized by Mr. Bell, who well foresaw, from its short,
broad head, and strong claws of equal length, that its habits
of life would turn out very peculiar, and different from those
of its nearest ally, the Iguana. It is extremely common on all
the islands throughout the group, and lives exclusively on the
rocky sea-beaches, being never found, at least I never saw
one, even ten yards in-shore. It is a hideous-looking crea-
ture, of a dirty black colour, stupid, and sluggish in its move-
ments. The usual length of a full-grown one is about a yard,
but there are some even four feet long; a large one weighed
twenty pounds: on the island of Albemarle they seem to
grow to a greater size than elsewhere. Their tails are flat-
tened sideways, and all four feet partially webbed. They are
occasionally seen some hundred yards from the shore,
swimming about; and Captain Collnett, in his Voyage says,

THE VOYAGE OF THE BEAGLE 409

" They go to sea in herds a-fishing, and sun themselves on
the rocks ; and may be called alligators in miniature." It
must not, however, be supposed that they live on fish. When
in the water this lizard swims with perfect ease and quick-
ness, by a serpentine movement of its body and flattened tail
— the legs being motionless and closely collapsed on its sides.
A seaman on board sank one, with a heavy weight attached
to it, thinking thus to kill it directly ; but when, an hour after-
wards, he drew up the line, it was quite active. Their limbs
and strong claws are admirably adapted for crawling over the
rugged and fissured masses of lava, which everywhere form
the coast. In such "situations, a group of six or seven of
these hideous reptiles may oftentimes be seen on the black
rocks, a few feet above the surf, basking in the sun with out-
stretched legs.

I opened the stomachs of several, and found them largely
distended with minced sea-weed (Ulvse), which grows in
thin foliaceous expansions of a bright green or a dull red
colour. I do not recollect having observed this sea-weed in
any quantity on the tidal rocks ; and I have reason to believe
it grows at the bottom of the sea, at some little distance from
the coast. If such be the case, the object of these animals
occasionally going out to sea is explained. The stomach con-
tained nothing but the sea-weed. Mr. Baynoe, however, found
a piece of crab in one; but this might have got in acci-
dentally, in the same manner as I have seen a caterpillar, in
the midst of some lichen, in the paunch of a tortoise. The
intestines were large, as in other herbivorous animals. The
nature of this lizard's food, as well as the structure of its
tail and feet, and the fact of its having been seen voluntarily
swimming out at sea, absolutely prove its aquatic habits;
yet there is in this respect one strange anomaly, namely, that
when frightened it will not enter the water. Hence it is
easy to drive these lizards down to any little point overhang-
ing the sea, where they will sooner allow a person to catch
hold of their tails than jump into the water. They do not
seem to have any notion of biting ; but when much frightened
they squirt a drop of fluid from each nostril. I threw one
several times as far as I could, into a deep pool left by the
retiring tide; but it invariably returned in a direct line to

410 CHARLES DARWIN

the spot where I stood. It swam near the bottom, with a
very graceful and rapid movement, and occasionally aided
itself over the uneven ground with its feet. As soon as it
arrived near the edge, but still being under water, it tried to
conceal itself in the tufts of sea-weed, or it entered some
crevice. As soon as it thought the danger was past, it
crawled out on the dry rocks, and shuffled away as quickly
as it could. I several times caught this same lizard, by driv-
ing it down to a point, and though possessed of such perfect
powers of diving and swimming, nothing would induce it to
enter the water ; and as often as I threw it in, it returned in
the manner above described. Perhaps this singular piece of
apparent stupidity may be accounted for by the circum-
stance, that this reptile has no enemy whatever on shore,
whereas at sea it must often fall a prey to the numerous
sharks. Hence, probably, urged by a fixed and hereditary
instinct that the shore is its place of safety, whatever the
emergency may be, it there takes refuge.

During our visit (in October), I saw extremely few snjall
individuals of this species, and none I should think under
a year old. From this circumstance it seems probable that
the breeding season had not then commenced. I asked sev-
eral of the inhabitants if they knew where it laid its eggs:
they said that they knew nothing of its propagation, although
well acquainted with the eggs of the land kind — a fact, con-
sidering how very common this lizard is, not a little extra-
ordinary.

We will now turn to the terrestrial species (A. Demarlii),
with a round tail, and toes without webs. This lizard,
instead of being found like the other on all the islands, is
confined to the central part of the archipelago, namely to
, Albemarle, James, Harrington, and Indefatigable islands. To
the southward, in Charles, Hood, and Chatham islands, and
to the northward, in Towers, Bindloes, and Abingdon, I
neither saw nor heard of any. It would appear as_ifjtjhail
been created in the centre of the archipelago, and thence had
been dispersed only to a certain distance. Some of these
lizards inhabit the high and damp parts of the islands, but
they are much more numerous in the lower and sterile
districts near the coast. I cannot give a more forcible proof

THE VOYAGE OF THE BEAGLE 411

of their numbers, than by stating that when we were left at
James Island, we could not for some time find a spot free
from their burrows on which to pitch our single tent. Like
their brothers the sea-kind, they are ugly animals, of a yellow-
ish orange beneath, and of a brownish red colour above:
from their low facial angle they have a singularly stupid
appearance. They are, perhaps, of a rather less size than the
marine species; but several of them weighed between ten and
fifteen pounds. In their movements they are lazy and half
torpid. When not frightened, they slowly crawl along with
their tails and bellies dragging on the ground. They often
stop, and doze for a minute or two, with closed eyes and hind
legs spread out on the parched soil.

They inhabit burrows, which they sometimes make between
fragments of lava, but more generally on level patches of the
soft sandstone-like tuff. The holes do not appear to be very
deep, and they enter the ground at a small angle; so that
when walking over these lizard-warrens, the soil is constantly
giving way, much to the annoyance of the tired walker. This
animal, when making its burrow, works alternately the oppo-
site sides of its body. One front leg for a short time
scratches up the soil, and throws it towards the hind foot,
which is well placed so as to heave it beyond the mouth of
the hole. That side of the body being tired, the other takes
up the task, and so on alternately. I watched one for a long
time, till half its body was buried ; I then walked up and pulled
it by the tail ; at this it was greatly astonished, and soon
shuffled up to see what was the matter; and then stared me
in the face, as much as to say, " What made you pull my
tail?"

They feed by day, and do not wander far from their bur-
rows; if frightened, they rush to them with a most awkward
gait. Except when running down hill, they cannot move
very fast, apparently from the lateral position of their legs.
They are not at all timorous : when attentively watching any
one, they curl their tails, and, raising themselves on their
front legs, nod their heads vertically, with a quick movement,
and try to look very fierce ; but in reality they are not at all
so: if one just stamps on the ground, down go their tails,
and off they shuffle as quickly as they can. I have frequently

412 CHARLES DARWIN

observed small fly-eating lizards, when watching anything,
nod their heads in precisely the same manner; but I do not
at all know for what purpose. If this Amblyrhynchus is held
and plagued with a stick, it will bite it very severely ; but
I caught many by the tail, and they never tried to bite me.
If two are placed on the ground and held together, they will
fight, and bite each other till blood is drawn.

The individuals, and they are the greater number, which
inhabit the lower country, can scarcely taste a drop of water
throughout the year; but they consume much of the succulent
cactus, the branches of which are occasionally broken off
by the wind. I several times threw a piece to two or three
of them when together ; and it was amusing enough to see
them trying to seize and carry it away in their mouths, like
so many hungry dogs with a bone. They eat very deliber-
ately, but do not chew their food. The little birds are aware
how harmless these creatures are : I have seen one of the
thick-billed finches picking at one end of a piece of cactus
(which is much relished by all the animals of the lower
region), whilst a lizard was eating at the other end; and
afterwards the little bird with the utmost indifference hopped
on the back of the reptile.

I opened the stomachs of several, and found them full of
vegetable fibres and leaves of different trees, especially of
an acacia. In the upper region they live chiefly on the acid
and astringent berries of the guayavita, under which trees
I have seen these lizards and the huge tortoises feeding
together. To obtain the acacia-leaves they crawl up the low
stunted trees; and it is not uncommon to see a pair quietly
browsing, whilst seated on a branch several feet above the
ground. These lizards, when cooked, yield a white meat,
which is liked by those whose stomachs soar above all
prejudices.

Humboldt has remarked that in intertropical South
America, all lizards which inhabit dry regions are esteemed
delicacies for the table. The inhabitants state that those
which inhabit the upper damp parts drink water, but that
the others do not, like the tortoises, travel up for it from
the lower sterile country. At the time of our visit, the
females had within their bodies numerous, large, elongated

THE VOYAGE OF THE BEAGLE 413

eggs, which they lay in their burrows: the inhabitants seek
them for food.

These two species of Amblyrhynchus agree, as I have
already stated, in their general structure, and in many of
their habits. Neither have that rapid movement, so charac-
teristic of the genera Lacerta and Iguana. They are both
herbivorous, although the kind of vegetation on which they
feed is so very different. Mr. Bell has given the name to the
genus from the shortness of the snout: indeed, the form of
the mouth may almost be compared to that of the tortoise:
one is led to suppose that this is an adaptation to their
herbivorous appetites. It is very interesting thus to find a
well-characterized genus, having its marine and terrestrial
species, belonging to so confined a portion of the world. The
aquatic species is by far the most remarkable, because it is
the only existing lizard which lives on marine vegetable pro-
ductions. As I at first observed, these islands are not so
remarkable for the number of the species of reptiles, as for
that of the individuals; when we remember the well-beaten
paths made by the thousands of huge tortoises — the many
turtles — the great warrens of the terrestrial Amblyrhynchus
— and the groups of the marine species basking on the coast-
rocks of every island — we must admit that there is no other
quarter of the world where this Order replaces the herbivo-
rous mammalia in so extraordinary a manner. The geologist
on hearing this will probably refer back in his mind to the
Secondary epochs, when lizards, some herbivorous, some
carnivorous, and of dimensions comparable only with our
existing whales, swarmed on the land and in the sea. It is,
therefore, worthy of his observation, that this archipelago,
instead of possessing a humid climate and rank vegetation,
cannot be considered otherwise than extremely arid, and, for
an equatorial region, remarkably temperate.

To finish with the zoology: the fifteen kinds of sea-fish
which I procured here are all new species; they belong to
twelve genera, all widely distributed, with the exception of
Prionotus, of which the four previously known species live
on the eastern side of America. Of land-shells I collected
sixteen kinds (and two marked varieties), of which, with the
exception of one Helix found at Tahiti, all are peculiar to

414 CHARLES DARWIN

this archipelago: a single fresh-water shell (Paludina) is
common to Tahiti and Van Diemen's Land. Mr. Cuming,
before our voyage, procured here ninety species of sea-shells,
and this does not include several species not yet specifically
examined, of Trochus, Turbo, Monodonta, and Nassa. He
has been kind enough to give me the following interesting
results: Of the ninety shells, no less than forty-seven are
unknown elsewhere — a wonderful fact, considering how
widely distributed sea-shells generally are. Of the forty-
three shells found in other parts of the world, twenty-five
inhabit the western coast of America, and of these eight are
distinguishable as varieties; the remaining eighteen (includ-
ing one variety) were found by Mr. Cuming in the Low
Archipelago, and some of them also at the Philippines. This
fact of shells from islands in the central parts of the Pacific
occurring here, deserves notice, for not one single sea-shell is
known to be common to the islands of that ocean and to the
west coast of America. The space of open sea running north
and south off the west coast, separates two quite distinct
conchological provinces; but at the Galapagos Archipelago
we have a halting-place, where many new forms have been
created, and whither these two great conchological provinces
have each sent up several colonists. The American province
has also sent here representative species ; for there is a Gala-
pageian species of Monoceros, a genus only found on the
west coast of America; and there are Galapageian species
of Fissurella and Cancellaria, genera common on the west
coast, but not found (as I am informed by Mr. Cuming) in
the central islands of the Pacific. On the other hand, there
are Galapageian species of Oniscia and Stylifer, genera com-
mon to the West Indies and to the Chinese and Indian seas,
but not found either on the west coast of America or in the
central Pacific. I may here add, that after the comparison
by Messrs. Cuming and Hinds of about 2000 shells from
the eastern and western coasts of America, only one single
shell was found in common, namely, the Purpura patula,
which inhabits the West Indies, the coast of Panama,
and the Galapagos. We have, therefore, in this quarter
of the world, three great conchological sea-provinces, quite
distinct, though surprisingly near each other, being sepa-

THE VOYAGE OF THE BEAGLE 415

rated by long north and south spaces either of land or of
open sea.

I took great pains in collecting the insects, but excepting
Tierra del Fuego, I never saw in this respect so poor a coun-
try. Even in the upper and damp region I procured very few,
excepting some minute Diptera and Hymenoptera, mostly of
common mundane forms. As before remarked, the insects,
for a tropical region, are of very small size and dull colours.
Of beetles I collected twenty-five species (excluding a Der-
mestes and Corynetes imported, wherever a ship touches) ;
of these, two belong to the Harpalidae, two to the Hydro-
philidae, nine to three families of the Heteromera, and the
remaining twelve to as many different families. This cir-
cumstance of insects (and I may add plants), where few in
number, belonging to many different families, is, I believe,
very general. Mr. Waterhouse, who has published* an
account of the insects of this archipelago, and to whom I am
indebted for the above details, informs me that th'ere are
several new genera: and that of the genera not new, one
or two are American, and the rest of mundane distribution.
With the exception of a wood-feeding Apate, and of one or
probably two water-beetles from the American continent,
all the species appear to be new.

The botany of this group is fully as interesting as the
zoology. Dr. J. Hooker will soon publish in the " Linnean
Transactions " a full account of the Flora, and I am much
indebted to him for the following details. Of flowering
plants there are, as far as at present is known, 185 species,
and 40 cryptogamic species, making altogether 225; of this
number I was fortunate enough to bring home 193. Of the
flowering plants, 100 are new species, and are probably con-
fined to this archipelago. Dr. Hooker conceives that, of the
plants not so confined, at least 10 species found near the
cultivated ground at Charles Island, have been imported.
It is, I think, surprising that more American species have
not been introduced naturally, considering that the distance
is only between 500 and 600 miles from the continent ; and
that (according to Collnet, p. 58) drift-wood, bamboos, canes,
and the nuts of a palm, are often washed on the south-eastern
• Ann. and Mag. of Nat. Hist, vol. xvi. p. 19.

416 CHARLES DARWIN

shores. The proportion of 100 flowering plants out of 185
(or 175 excluding the imported weeds) being new, is suffi-
cient, I conceive, to make the Galapagos Archipelago a dis-
tinct botanical province ; but this Flora is not nearly so
peculiar as that of St. Helena, nor, as I am informed by
Dr. Hooker, of Juan Fernandez. The peculiarity of the
Galapageian Flora is best shown in certain families; — thus
there are 21 species of Composite, of which 20 are peculiar
to this archipelago; these belong to twelve genera, and of
these genera no less than ten are confined to the archipelago !
Dr. Hooker informs me that the Flora has an undoubtedly
Western American character; nor can he detect in it any
affinity with that of the Pacific. If, therefore, we except the
eighteen marine, the one fresh-water, and one land-shell,
which have apparently come here as colonists from the
central islands of the Pacific, and likewise the one distinct
Pacific species of the Galapageian group of finches, we see
that this archipelago, though standing in the Pacific Ocean,
is zoologically part of America.

'if this character were owing merely to immigrants from
America, there would be little remarkable in it ; but we see
that a vast majority of all the land animals, and that more
than half of the flowering plants, are aboriginal productions.
"It was most striking to be surrounded by new birds, new rep-
tiles, new shells, new insects, new plants, and yet by innumer-
able trifling details of structure, and even by the tones of
voice and plumage of the birds, to have the temperate plains
of Patagonia, or rather the hot dry deserts of Northern Chile,
vividly brought before my eyes. Why, on these small points
of land, which within a late geological period must have
been covered by the ocean, which are formed by basaltic lava,
and therefore differ in geological character from the Ameri-
can continent, and which are placed under a peculiar climate,
— why were their aboriginal inhabitants, associated, I may
add, in different proportions both in kind and number from
those on the continent, and therefore acting on each other
in a different manner — why were they created on American
types of organization ? It is probable that the islands of the
Cape de Verd group resemble, in all their physical conditions,
far more closely the Galapagos Islands, than these latter

THE VOYAGE OF THE BEAGLE 417

physically resemble the coast of America, yet the aboriginal
inhabitants of the two groups are totally unlike ; those of the
Cape de Verd Islands bearing the impress of Africa, as
the inhabitants of the Galapagos Archipelago are stamped
with that of America.

I have not as yet noticed by far the most remarkable fea-
ture in the natural history of this archipelago; it is, that
the different islands to a considerable extent are inhabited by
a different set of beings. My attention was first called to
this fact by the Vice-Governor, Mr. Lawson, declaring that
the tortoises differed from the different islands, and that he
could with certainty tell from which island any one was
brought. I did not for some time pay sufficient attention
to this statement, and I had already partially mingled to-
gether the collections from two of the islands. I never
dreamed that islands, about 50 or 60 miles apart, and most of
them in sight of each other, formed of precisely the same
rocks, placed under a quite similar climate, rising to a nearly
equal height, would have been differently tenanted; but we
shall soon see that this is the case. It is the fate of most
voyagers, no sooner to discover what is most interesting in
any locality, than they are hurried from it; but I ought, per-
haps, to be thankful that I obtained sufficient materials to
establish this most remarkable fact in the distribution of
organic beings.

The inhabitants, as I have said, state that they can dis-
tinguish the tortoises from the different islands; and that
they differ not only in size, but in other characters. Captain
Porter has described3 those from Charles and from the near-
est island to it, namely, Hood Island, as having their shells
in front thick and turned up like a Spanish saddle, whilst
the tortoises from James Island are rounder, blacker, and
have a better taste when cooked. M. Bibron, moreover,
informs me that he has seen what he considers two distinct
species of tortoise from the Galapagos, but he does not know
from which islands. The specimens that I brought from
three islands were young ones : and probably owing to this
cause neither Mr. Gray nor myself could find in them any

* Voyage in the U. S. ship Essex, vol. i. p. 215.

VOL. XXIX — N HC

418 CHARLES DARWIN

specific differences. I have remarked that the marine
Amblyrhynchus was larger at Albemarle Island than else-
where; and M. Bibron informs me that he has seen two dis-
tinct aquatic species of this genus; so that the different
islands probably have their representative species or races
of the Amblyrhynchus, as well as of the tortoise. My atten-
tion was first thoroughly aroused, by comparing together
the numerous specimens, shot by myself and several other
parties on board, of the mocking-thrushes, when, to my aston-
ishment, I discovered that all those from Charles Island
belonged to one species (Mimus trifasciatus) ; all from
Albemarle Island to M. parvulus; and all from James and
Chatham Islands (between which two other islands are sit-
uated, as connecting links) belonged to M. melanotis. These
two latter species are closely allied, and would by some
ornithologists be considered as only well-marked races or
varieties; but the Mimus trifasciatus is very distinct. Un-
fortunately most of the specimens of the finch tribe were
mingled together; but I have strong reasons to suspect that
some of the species of the sub-group Geospiza are confined
to separate islands. If the different islands have their repre-
sentatives of Geospiza, it may help to explain the singularly
large number of the species of this sub-group in this one
small archipelago, and as a probable consequence of their
numbers, the perfectly graduated series in the size of their
beaks. Two species of the sub-group Cactornis, and two of
the Camarhynchus, were procured in the archipelago; and
of the numerous specimens of these two sub-groups shot by
four collectors at James Island, all were found to belong to
one species of each; whereas the numerous specimens shot
either on Chatham or Charles Island (for the two sets were
mingled together) all belonged to the two other species:
hence we may feel almost sure that these islands possess >
their respective species of these two sub-groups. In land-
shells this law of distribution does not appear to hold good.
In my very small collection of insects, Mr. Waterhouse
remarks, that of those which were ticketed with their local-
ity, not one was common to any two of the islands.

If we now turn to the Flora, we shall find the aboriginal
plants of the different islands wonderfully different. I give

THE VOYAGE OF THE BEAGLE

419

all the following results on the high authority of my friend
Dr. J. Hooker. I may premise that I indiscriminately col-
lected everything in flower on the different islands, and for-
tunately kept my collections separate. Too much confidence,
however, must not be placed in the proportional results, as
the small collections brought home by some other naturalists,
though in some respects confirming the results, plainly show
that much remains to be done in the botany of this group:
the Leguminosae, moreover, has as yet been only approxi-
mately worked out : —

(or 29. if the

Hence we have the truly wonderful fact, that in James
Island, of the thirty-eight Galapageian plants, or those found
in no other part of the world, thirty are exclusively confined
to this one island; and in Albemarle Island, of the twenty-
six aboriginal Galapageian plants, twenty-two are confined
to this one island, that is, only four are at present known to
grow in the other islands of the archipelago; and so on, as
shown in the above table, with the plants from Chatham and
Charles Islands. This fact will, perhaps, be rendered even
more striking, by giving a few illustrations: — thus, Scalesia,
a remarkable arborescent genus of the Compositae, is con-
fined to the archipelago: it has six species: one from Chat-
ham, one from Albemarle, one from Charles Island, two from
James Island, and the sixth from one of the three latter
islands, but it is not known from which : not one of these six
species grows on any two islands. Again, Euphorbia, a mun- .

420 CHARLES DARWIN

dane or widely distributed genus, has here eight species, of
which seven are confined to the archipelago, and not one
found on any two islands : Acalypha and Borreria, both mun-
dane genera, have respectively six and seven species, none
of which have the same species on two islands, with the
exception of one Borreria, which does occur on two islands.
The species of the Compositae are particularly local ; and Dr.
Hooker has furnished me with several other most striking
illustrations of the difference of the species on the different
islands. He remarks that this law of distribution holds good
both with those genera confined to the archipelago, and those
distributed in other quarters of the world: in like manner
we have seen that the different islands have their proper spe-
cies of the mundane genus of tortoise, and of the widely
distributed American genus of the mocking-thrush, as well
as of two of the Galapageian sub-groups of finches, and
almost certainly of the Galapageian genus Amblyrhynchus.

The distribution of the tenants of this archipelago would
not be nearly so wonderful, if, for instance, one island had
a mocking-thrush, and a second island some other quite dis-
tinct genus; — if one island had its genus of lizard, and a
second island another distinct genus, or none whatever; — or
if the different islands were inhabited, not by representative
species of the same genera of plants, but by totally different
genera, as does to a certain extent hold good: for, to give
one instance, a large berry-bearing tree at James Island has
no representative species in Charles Island. [JBut it is the
circumstance, that several of the islands possess their own
species of the tortoise, mocking-thrush, finches, and numer-
ous plants, these species having the same general habits,
occupying analogous situations, and obviously filling the
same place in the natural economy of this archipelago, that
strikes me with wonder.^JTt may be suspected that some of
these representative species, at least in the case of the tor-
toise and of some of the birds, may hereafter prove to be
only well-marked races ; but this would be of equally great
interest to the philosophical naturalist. I have said that most
of the islands are in sight of each other: I may specify that
Charles Island is fifty miles from the nearest part of Chat-
ham Island, and thirty-three miles from the nearest part of

THE VOYAGE OF THE BEAGLE 421

Albemarle Island. Chatham Island is sixty miles from the
nearest part of James Island, but there are two intermediate
islands between them which were not visited by me. James
Island is only ten miles from the nearest part of Albemarle
Island, but the two points where the collections were made
are thirty-two miles apart. I must repeat, that neither the
nature of the soil, nor height of the land, nor the climate,
nor the general character of the associated beings, and there-
fore their action one on another, can differ much in the dif-
ferent islands. If there be any sensible difference in their
climates, it must be between the Windward group (namely,
Charles and Chatham Islands), and that to leeward; but
there seems to be no corresponding difference in the produc-
tions of these two halves of the archipelago.

The only light which I can throw on this remarkable dif-
ference in the inhabitants of the different islands, is, that
very strong currents of the sea running in a westerly and
W.N.W. direction must separate, as far as transportal by the
sea is concerned, the southern islands from the northern
ones ; and between these northern islands a strong N.W. cur-
rent was observed, which must effectually separate James
and Albemarle Islands. (As the archipelago is free to a
most remarkable degree from gales of wind, neither the
birds, insects, nor lighter seeds, would be blown from island
to island^/ And lastly, the profound depth of the ocean be-
tween the islands, and their apparently recent (in a geologi-
cal sense) volcanic origin, render it highly unlikely that they
were ever united ; and this, probably, is a far more important
consideration than any other, with respect to the geographi-
cal distribution of their inhabitants. Reviewing the facts
here given, one is astonished at the amount of creative force,
if such an expression may be used, displayed on these small,
barren, and rocky islands; and still more so, at its diverse
yet analogous action on points so near each other. I have
said that the Galapagos Archipelago might be called a satel-
lite attached to America, but it should rather be called a
group of satellites, physically similar, organically distinct,
yet intimately related to each other, and all related in a
marked, though much lesser degree, to the great American
continent.

422 CHARLES DARWIN

I will conclude my description of the natural history of
these islands, by giving an account of the extreme tameness
of the birds.

This disposition is common to all the terrestrial species;
namely, to the mocking-thrushes, the finches, wrens, tyrant-
flycatchers, the dove, and carrion-buzzard. All of them are
often approached sufficiently near to be killed with a switch,
and sometimes, as I myself tried, with a cap or hat. A gun
is here almost superfluous; for with the muzzle I pushed a
hawk off the branch of a tree. One day, whilst lying down,
a mocking-thrush alighted on the edge of a pitcher, made of
the shell of a tortoise, which I held in my hand, and began
very quietly to sip the water; it allowed me to lift it from
the ground whilst seated on the vessel: I often tried, and
very nearly succeeded, in catching these birds by their legs.
Formerly the birds appear to have been even tamer than at
present. Cowley (in the year 1684) says that the " Turtle-
doves were so tame, that they would often alight on our hats
and arms, so as that we could take them alive ; they not fear-
ing man, until such time as some of our company did fire at
them, whereby they were rendered more shy." Dampier
also, in the same year, says that a man in a morning's walk
might kill six or seven dozen of these doves. At present,
although certainly very tame, they do not alight on people's
arms, nor do they suffer themselves to be killed in such large
numbers. It is surprising that they have not become wilder ;
for these islands during the last hundred and fifty years have
been frequently visited by bucaniers and whalers; and the
sailors, wandering through the wood in search of tortoises,
always take cruel delight in knocking down the little birds.

These birds, although now still more persecuted, do not
readily become wild. In Charles Island, which had then
been colonized about six years, I saw a boy sitting by a well
with a switch in his hand, with which he killed the doves
and finches as they came to drink. He had already procured
a little heap of them for his dinner; and he said that he had
constantly been in the habit of waiting by this well for the
same purpose. It would appear that the birds of this archi-
pelago, not having as yet learnt that man is a more danger-
ous animal than the tortoise or the Amblyrhynchus, disregard

THE VOYAGE OF THE BEAGLE 423

him, in the same manner as in England shy birds, such as
magpies, disregard the cows and horses grazing in our fields.

The Falkland Islands offer a second instance of birds
with a similar disposition. The extraordinary tameness of
the little Opetiorhynchus has been remarked by Pernety,
Lesson, and other voyagers. It is not, however, peculiar to
that bird: the Polyborus, snipe, upland and lowland goose,
thrush, bunting, and even some true hawks, are all more or
less tame. As the birds are so tame there, where foxes,
hawks, and owls occur, we may infer that the absence of all
rapacious animals at the Galapagos, is not the cause of their
tameness here. The upland geese at the Falklands show, by
the precaution they take in building on the islets, that they
are aware of their danger from the foxes ; but they are not
by this rendered wild towards man. This tameness of the
birds, especially of the waterfowl, is strongly contrasted with
the habits of the same species in Tierra del Fuego, where for
ages past they have been persecuted by the wild inhabitants.
In the Falklands, the sportsman may sometimes kill more
of the upland geese in one day than he can carry home;
whereas in Tierra del Fuego it is nearly as difficult to kill
one, as it is in England to shoot the common wild goose.

In the time of Pernety (1763), all the birds there appear
to have been much tamer than at present ; he states that the
Opetiorhynchus would almost perch on his finger; and that
with a wand he killed ten in half an hour. At that period
the birds must have been about as tame as they now are at
the Galapagos. They appear to have learnt caution more
slowly at these latter islands than at the Falklands, where
they have had proportionate means of experience; for be-
sides frequent visits from vessels, those islands have been at
intervals colonized during the entire period. Even formerly,
when all the birds were so tame, it was impossible by Per-
nety's account to kill the black-necked swan — a bird of
passage, which probably brought with it the wisdom learnt
in foreign countries.

I may add that, according to Du Bois, all the birds at
Bourbon in 1571-72, with the exception of the flamingoes
and geese, were so extremely tame, that they could be caught
by the hand, or killed in any number with a stick. Again,

424 CHARLES DARWIN

at Tristan d'Acunha in the Atlantic, Carmichael* states that
the only two land-birds, a thrush and a bunting, were " so
tame as to suffer themselves to be caught with a hand-net."
From these several facts we may, I think, conclude, first, that
the wildness of birds with regard to man, is a particular
instinct directed against him, and not dependent upon any
general degree of caution arising from other sources of
danger; secondly, that it is not acquired by individual birds
in a short time, even when much persecuted; but that in the
course of successive generations it becomes hereditary. With
domesticated animals we are accustomed to see new mental
habits or instincts acquired or rendered hereditary; but with
animals in a state of nature, it must always be most difficult
to discover instances of acquired hereditary knowledge. In
regard to the wildness of birds towards man, there is no way
of accounting for it, except as an inherited habit: compara-
tively few young birds, in any one year, have been injured
by man in England, yet almost all, even nestlings, are afraid
of him; many individuals, on the other hand, both at the
Galapagos and at the Falklands, have been pursued and
injured by man, yet have not learned a salutary dread of
him. We may infer from these facts, what havoc the intro-
duction of any new beast of prey must cause in a country,
before the instincts of the indigenous inhabitants have
become adapted to the stranger's craft or power.

6 Linn. Trans., vol. xii. p. 496. The most anomalous fact on this sub-
ject which I have met with is the wildness of the small birds in the Arctic
parts of North America (as described by Richardson, Fauna Bor., vol. ii.
P- 332). where they are said never to be persecuted. This case is the more
strange, because it is asserted that some of the same species in their winter-
quarters in the United States are tame. There is much, as Dr. Richardson
well remarks, utterly inexplicable connected with the different degrees of
shyness and care with which birds conceal their nests. How strange it
is that the English wood-pigeon, generally so wild a bird, should very fre«
quently rear its young in shrubberies close to houses 1

OCTOBER 20th.— The survey of the Galapagos Archi-
pelago being concluded, we steered towards Tahiti
and commenced our long passage of 3200 miles. In
the course of a few days we sailed out of the gloomy and
clouded ocean-district which extends during the winter far
from the coast of South America. We then enjoyed bright
and clear weather, while running pleasantly along at the
rate of 150 or 160 miles a day before the steady trade-wind.
The temperature in this more central part of the Pacific is
higher than near the American shore. The thermometer in
the poop cabin, by night and day, ranged between 80° and
83°, which feels very pleasant; but with one degree or two
higher, the heat becomes oppressive. We passed through
the Low or Dangerous Archipelago, and saw several of
those most curious rings of coral land, just rising above the
water's edge, which have been called Lagoon Islands. A
long and brilliantly white beach is capped by a margin of
green vegetation; and the strip, looking either way, rapidly
narrows away in the distance, and sinks beneath the horizon.
From the mast-head a wide expanse of smooth water can be
seen within the ring. These low hollow coral islands bear
no proportion to the vast ocean out of which they abruptly
rise; and it seems wonderful, that such weak invaders are
not overwhelmed, by the all-powerful and never-tiring waves
of that great sea, miscalled the Pacific.

426 CHARLES DARWIN

November i^th. — At daylight, Tahiti, an island which
must for ever remain classical to the voyager in the South
Sea, was in view. At a distance the appearance was not
attractive. The luxuriant vegetation of the lower part could
not yet be seen, and as the clouds rolled past, the wildest
and most precipitous peaks showed themselves towards the
centre of the island. As soon as we anchored in Matavai
Bay, we were surrounded by canoes. This was our Sunday,
but the Monday of Tahiti: if the case had been reversed,
we should not have received a single visit; for the injunction
not to launch a canoe on the sabbath is rigidly obeyed.
After dinner we landed to enjoy all the delights produced
by the first impressions of a new country, and that country
the charming Tahiti. A crowd of men, women, and children,
was collected on the memorable Point Venus, ready to
receive us with laughing, merry faces. They marshalled
us towards the house of Mr. Wilson, the missionary of the
district, who met us on the road, and gave us a very friendly
reception. After sitting a very short time in his house, we
separated to walk about, but returned there in the evening.

The land capable of cultivation, is scarcely in any part
more than a fringe of low alluvial soil, accumulated round
the base of the mountains, and protected from the waves of
the sea by a coral reef, which encircles the entire line of
coast. Within the reef there is an expanse of smooth water,
like that of a lake, where the canoes of the natives can ply
with safety and where ships anchor. The low land which
comes down to the beach of coral-sand, is covered by the
most beautiful productions of the intertropical regions. In
the midst of bananas, orange, cocoa-nut, and bread-fruit
trees, spots are cleared where yams, sweet potatoes, and
sugar-cane, and pine-apples are cultivated. Even the brush-
wood is an imported fruit-tree, namely, the guava, which
from its abundance has become as noxious as a weed. In
Brazil I have often admired the varied beauty of the
bananas, palms, and orange-trees contrasted together; and
here we also have the bread-fruit, conspicuous from its large,
glossy, and deeply digitated leaf. It is admirable to behold
groves of a tree, sending forth its branches with the vigour
of an English oak, loaded with large and most nutritious

THE VOYAGE OF THE BEAGLE 427

fruit. However seldom the usefulness of an object can
account for the pleasure of beholding it, in the case of these
beautiful woods, the knowledge of their high productiveness
no doubt enters largely into the feeling of admiration. The
little winding paths, cool from the surrounding shade, led
to the scattered houses; the owners of which everywhere
gave us a cheerful and most hospitable reception.

I was pleased with nothing so much as with the inhabit-
ants. There is a mildness in the expression of their coun-
tenances which at once banishes the idea of a savage; and
an intelligence which shows that they are advancing in civili-
zation. The common people, when working, keep the upper
part of their bodies quite naked; and it is then that the
Tahitians are seen to advantage. They are very tall, broad-
shouldered, athletic, and well-proportioned. It has been
remarked, that it requires little habit to make a dark skin
more pleasing and natural to the eye of an European than
his own colour. A white man bathing by the side of a
Tahitian, was like a plant bleached by the gardener's art
compared with a fine dark green one growing vigorously in
the open fields. Most of the men are tattooed, and the orna-
ments follow the curvature of the body so gracefully, that
they have a very elegant effect. One common pattern, vary-
ing in its details, is somewhat like the crown of a palm-tree.
It springs from the central line of the back, and gracefully
curls round both sides. The simile may be a fanciful one,
but I thought the body of a man thus ornamented was like
the trunk of a noble tree embraced by a delicate creeper.

Many of the elder people had their feet covered with
small figures, so placed as to resemble a sock. This fashion,
however, is partly gone by, and has been succeeded by others.
Here, although fashion is far from immutable, every one
must abide by that prevailing in his youth. An old man
has thus his age for ever stamped on his body, and he cannot
assume the airs of a young dandy. The women are tattooed
in the same manner as the men, and very commonly on their
fingers. One unbecoming fashion is now almost universal:
namely, shaving the hair from the upper part of the head,
in a circular form, so as to leave only an outer ring. The
missionaries have tried to persuade the people to change this

428 CHARLES DARWIN

habit; but it is the fashion, and that is a sufficient answer
at Tahiti, as well as at Paris. I was much disappointed in
the personal appearance of the women: they are far inferior
in every respect to the men. The custom of wearing a white
or scarlet flower in the back of the head, or through a small
hole in each ear, is pretty. A crown of woven cocoa-nut
leaves is also worn as a shade for the eyes. The women
appear to be in greater want of some becoming costume even
than the men.

Nearly all the natives understand a little English — that is,
they know the names of common things; and by the aid of
this, together with signs, a lame sort of conversation could
be carried on. In returning in the evening to the boat, we
stopped to witness a very pretty scene. Numbers of chil-
dren were playing on the beach, and had lighted bonfires
which illumined the placid sea and surrounding trees;
others, in circles, were singing Tahitian verses. We seated
ourselves on the sand, and joined their party. The songs
were impromptu, and I believe related to our arrival: one
little girl sang a line, which the rest took up in parts, form-
ing a very pretty chorus. The whole scene made us une-
quivocally aware that we were seated on the shores of an
island in the far-famed South Sea.

lyth. — This day is reckoned in the log-book as Tuesday
the i7th, instead of Monday the i6th, owing to our, so far,
successful chase of the sun. Before breakfast the ship was
hemmed in by a flotilla of canoes; and when the natives
were allowed to come on board, I suppose there could not
have been less than two hundred. It was the opinion of
every one that it would have been difficult to have picked out
an equal number from any other nation, who would have
given so little trouble. Everybody brought something for
sale: shells were the main articles of trade. The Tahitians
now fully understand the value of money, and prefer it to
old clothes or other articles. The various coins, however, of
English and Spanish denomination puzzle them, and they
never seemed to think the small silver quite secure until
changed into dollars. Some of the chiefs have accumulated
considerable sums of money. One chief, not long since,
offered 800 dollars (about i6ol. sterling) for a small vessel;

429

and frequently they purchase whale-boats and horses at the
rate of from 50 to 100 dollars.

After breakfast I went on shore, and ascended the nearest
slope to a height of between two and three thousand feet.
The outer mountains are smooth and conical, but steep; and
the old volcanic rocks, of which they are formed, have been
cut through by many profound ravines, diverging from the
central broken parts of the island to the coast. Having
crossed the narrow low girt of inhabited and fertile land,
I followed a smooth steep ridge between two of the deep
ravines. The vegetation was singular, consisting almost
exclusively of small dwarf ferns, mingled higher up, with
coarse grass; it was not very dissimilar from that on some
of the Welsh hills, and this so close above the orchard of
tropical plants on the coast was very surprising. At the
highest point, which I reached, trees again appeared. Of
the three zones of comparative luxuriance, the lower one
owes its moisture, and therefore fertility, to its flatness ; for,
being scarcely raised above the level of the sea, the water
from the higher land drains away slowly. The intermediate
zone does not, like the upper one, reach into a damp and
cloudy atmosphere, and therefore remains sterile. The
woods in the upper zone are very pretty, tree-ferns replacing
the cocoa-nuts on the coast. It must not, however, be
supposed that these woods at all equal in splendour the
forests of Brazil. The vast numbers of productions, which
characterize a continent, cannot be expected to occur in
an island.

From the highest point which I attained, there was a good
view of the distant island of Eimeo, dependent on the same
sovereign with Tahiti. On the lofty and broken pinnacles,
white massive clouds were piled up, which formed an island
in the blue sky, as Eimeo itself did in the blue ocean. The
island, with the exception of one small gateway, is completely
encircled by a reef. At this distance, a narrow but well-
defined brilliantly white line was alone visible, where the
waves first encountered the wall of coral. The mountains
rose abruptly out of the glassy expanse of the lagoon, in-
cluded within this narrow white line, outside which the heav-
ing waters of the ocean were dark-coloured. The view was

430 CHARLES DARWIN

striking: it may aptly be compared to a framed engraving,
where the frame represents the breakers, the marginal paper
the smooth lagoon, and the drawing the island itself. When
in the evening I descended from the mountain, a man, whom
I had pleased with a trifling gift, met me, bringing with him
hot roasted bananas, a pine-apple, and cocoa-nuts. After
walking under a burning sun, I do not know anything more
delicious than the milk of a young cocoa-nut. Pine-apples
are here so abundant that the people eat them in the same
wasteful manner as we might turnips. They are of an excel-
lent flavor — perhaps even better than those cultivated in
England; and this I believe is the highest compliment which
can be paid to any fruit. Before going on board, Mr. Wilson
interpreted for me to the Tahitian who had paid me so adroit
an attention, that I wanted him and another man to accom-
pany me on a short excursion into the mountains.

i8th. — In the morning I came on shore early, bringing
with me some provisions in a bag, and two blankets for my-
self and servant. These were lashed to each end of a long
pole, which was alternately carried by my Tahitian com-
panions on their shoulders. These men are accustomed thus
to carry, for a whole day, as much as fifty pounds at each
end of their poles. I told my guides to provide themselves
with food and clothing; but they said that there was plenty
of food in the mountains, and for clothing, that their skins
were sufficient. Our line of march was the valley of Tia-
auru, down which a river flows into the sea by Point Venus.
This is one of the principal streams in the island, and its
source lies at the base of the loftiest central pinnacles,
which rise to a height of about 7000 feet. The whole island
is so mountainous that the only way to penetrate into the
interior is to follow up the valleys. Our road, at first, lay
through woods which bordered each side of the river; and
the glimpses of the lofty central peaks, seen as through an
avenue, with here and there a waving cocoa-nut tree on one
side, were extremely picturesque. The valley soon began to
narrow, and the sides to grow lofty and more precipitous.
After having walked between three and four hours, we
found the width of the ravine scarcely exceeded that of the
bed of the stream. On each hand the walls were nearly ver-

THE VOYAGE OF THE BEAGLE 431

tical; yet from the soft nature of the volcanic strata, trees
and a rank vegetation sprung from every projecting ledge.
These precipices must have been some thousand feet high;
and the whole formed a mountain gorge far more magnifi-
cent than anything which I had ever before beheld. Until
the midday sun stood vertically over the ravine, the air felt
cool and damp, but now it became very sultry. Shaded by a
ledge of rock, beneath a faqade of columnar lava, we ate our
dinner. My guides had already procured a dish of small
fish and fresh-water prawns. They carried with them a
small net stretched on a hoop; and where the water was
deep and in eddies, they dived, and like otters, with their
eyes open followed the fish into holes and corners, and thus
caught them.

The Tahitians have the dexterity of amphibious animals
in the water. An anecdote mentioned by Ellis shows how
much they feel at home in this element. When a horse was
landing for Pomarre in 1817, *ne slings broke, and it fell
into the water; immediately the natives jumped overboard,
and by their cries and vain efforts at assistance almost
drowned it. As soon, however, as it reached the shore, the
whole population took to flight, and tried to hide themselves
from the man-carrying pig, as they christened the horse.

A little higher up, the river divided itself into three little
streams. The two northern ones were impracticable, owing
to a succession of waterfalls which descended from the
jagged summit of the highest mountain; the other to all
appearance was equally inaccessible, but we managed to as-
cend it by a most extraordinary road. The sides of the
valley were here nearly precipitous; but, as frequently hap-
pens with stratified rocks, small ledges projected, which were
thickly covered by wild bananas, lilaceous plants, and other
luxuriant productions of the tropics. The Tahitians, by
climbing amongst these ledges, searching for fruit, had dis-
covered a track by which the whole precipice could be scaled.
The first ascent from the valley was very dangerous; for it
was necessary to pass a steeply inclined face of naked rock,
by the aid of ropes which we brought with us. How any
person discovered that this formidable spot was the only
point where the side of the mountain was practicable, I can-

432 CHARLES DARWIN

not imagine. We then cautiously walked along one of the
ledges till we came to one of the three streams. This ledge
formed a flat spot, above which a beautiful cascade, some
hundred feet in height, poured down its waters, and beneath,
another high cascade fell into the main stream in the val-
ley below. From this cool and shady recess we made a
circuit to avoid the overhanging waterfall. As before, we
followed little projecting ledges, the danger being partly
concealed by the thickness of the vegetation. In passing
from one of the ledges to another, there was a vertical wall
of rock. One of the Tahitians, a fine active man, placed
the trunk of a tree against this, climbed up it, and then by
the aid of crevices reached the summit. He fixed the ropes
to a projecting point, and lowered them for our dog and
luggage, and then we clambered up ourselves. Beneath the
ledge on which the dead tree was placed, the precipice must
have been five or six hundred feet deep; and if the abyss
had not been partly concealed by the overhanging ferns and
lilies my head would have turned giddy, and nothing should
have induced me to have attempted it. We continued to
ascend, sometimes along ledges, and sometimes along knife-
edged ridges, having on each hand profound ravines. In
the Cordillera I have seen mountains on a far grander
scale, but for abruptness, nothing at all comparable with this.
In the evening we reached a flat little spot on the banks
of the same stream, which we had continued to follow, and
which descends in a chain of waterfalls : here we bivouacked
for the night. On each side of the ravine there were great
beds of the mountain-banana, covered with ripe fruit. Many
of these plants were from twenty to twenty-five feet high,
and from three to four in circumference. By the aid of
strips of bark for rope, the stems of bamboos for rafters,
and the large leaf of the banana for a thatch, the Tahitians
in a few minutes built us an excellent house; and with
withered leaves made a soft bed.

They then proceeded to make a fire, and cook our evening
meal. A light was procured, by rubbing a blunt pointed
stick in a groove made in another, as if with intention of
deepening it, until by the friction the dust became ignited.
A peculiarly white and very light wood (the Hibiscus tilia-

THE VOYAGE OF THE BEAGLE 433

ceus) is alone used for this purpose: it is the same which
serves for poles to carry any burden, and for the floating
out-riggers to their canoes. The fire was produced in a few
seconds: but to a person who does not understand the art,
it requires, as I found, the greatest exertion; but at last, to
my great pride, I succeeded in igniting the dust. The
Gaucho in the Pampas uses a different method: taking an
elastic stick about eighteen inches long, he presses one end
on his breast, and the other pointed end into a hole in a piece
of wood, and then rapidly turns the curved part, like a car-
penter's centre-bit. The Tahitians having made a small fire
of sticks, placed a score of stones, of about the size of
cricket-balls, on the burning wood. In about ten minutes the
sticks were consumed, and the stones hot. They had previ-
ously folded up in small parcels of leaves, pieces of beef,
fish, ripe and unripe bananas, and the tops of the wild arum.
These green parcels were laid in a layer between two layers
of the hot stones, and the whole then covered up with
earth, so that no smoke or steam could escape. In about
a quarter of an hour, the whole was most deliciously cooked.
The choice green parcels were now laid on a cloth of
banana leaves, and with a cocoa-nut shell we drank the
cool water of the running stream ; and thus we enjoyed our
rustic meal.

I could not look on the surrounding plants without ad-
miration. On every side were forests of banana; the fruit
of which, though serving for food in various ways, lay in
heaps decaying on the ground. In front of us there was an
extensive brake of wild sugar-cane; and the stream was
shaded by the dark green knotted stem of the Ava, — so fa-
mous in former days for its powerful intoxicating effects. I
chewed a piece, and found that it had an acrid and unpleasant
taste, which would have induced any one at once to
have pronounced it poisonous. Thanks to the missionaries,
this plant now thrives only in these deep ravines, innocuous to
every one. Close by I saw the wild arum, the roots of which,
when well baked, are good to eat, and the young leaves
better than spinach. There was the wild yam, and a liliaceous
plant called Ti, which grows in abundance, and has a soft
brown root, in shape and size like a huge log of wood: this

434 CHARLES DARWIN

served us for dessert, for it is as sweet as treacle, and with
a pleasant taste. There were, moreover, several other wild
fruits, and useful vegetables. The little stream, besides its
cool water, produced eels, and cray-fish. I did indeed admire
this scene, when I compared it with an uncultivated one in
the temperate zones. I felt the force of the remark, that
man, at least savage man, with his reasoning powers only
partly developed, is the child of the tropics.

As the evening drew to a close, I strolled beneath the
gloomy shade of the bananas up the course of the stream.
My walk was soon brought to a close, by coming to a water-
' fall between two and three hundred feet high; and again
above this there was another. I mention all these waterfalls
in this one brook, to give a general idea of the inclination
of the land. In the little recess where the water fell, it did
not appear that a breath of wind had ever blown. The thin
edges of the great leaves of the banana, damp with spray,
were unbroken, instead of being, as is so generally the case,
split into a thousand shreds. From our position, almost sus-
pended on the mountain side, there were glimpses into the
depths of the neighbouring valleys; and the lofty points of
the central mountains, towering up within sixty degrees of
the zenith, hid half the evening sky. Thus seated, it was
a sublime spectacle to watch the shades of night gradually
obscuring the last and highest pinnacles.

Before we laid ourselves down to sleep, the elder Tahitian
fell on his knees, and with closed eyes repeated a long
prayer in his native tongue. He prayed as a Christian should
do, with fitting reverence, and without the fear of ridicule
or any ostentation of piety. At our meals neither of the men
would taste food, without saying beforehand a short grace.
Those travellers who think that a Tahitian prays only when
the eyes of the missionary are fixed on him, should have
slept with us that night on the mountain-side. Before morn-
ing it rained very heavily; but the good thatch of banana-
leaves kept us dry.

November ipth. — At daylight my friends, after their
morning prayer, prepared an excellent breakfast in the same
manner as in the evening. They themselves certainly par-
took of it largely; indeed I never saw any men eat near so

THE VOYAGE OF THE BEAGLE 135

much. I suppose such enormously capacious stomachs must
be the effect of a large part of their diet consisting of fruit
and vegetables, which contain, in a given bulk, a compara-
tively small portion of nutriment. Unwittingly, I was the
means of my companions breaking, as I afterwards learned,
one of their own laws, and resolutions: I took with me a
flask of spirits, which they could not refuse to partake of;
but as often as they drank a little, they put their fingers
before their mouths, and uttered the word " Missionary."
About two years ago, although the use of the ava was pre-
vented, drunkenness from the introduction of spirits became
very prevalent. The missionaries prevailed on a few good
men, who saw that their country was rapidly going to ruin,
to join with them in a Temperance Society. From good
sense or shame, all the chiefs and the queen were at last per-
suaded to join. Immediately a law was passed, that no
spirits should be allowed to be introduced into the island,
and that he who sold and he who bought the forbidden
article should be punished by a fine. With remarkable jus-
tice, a certain period was allowed for stock in hand to be
sold, before the law came into effect. But when it did, a
general search was made, in which even the houses of the
missionaries were not exempted, and all the ava (as the
natives call all ardent spirits) was poured on the ground.
When one reflects on the effect of intemperance on the
aborigines of the two Americas, I think it will be acknowl-
edged that every well-wisher of Tahiti owes no common debt
of gratitude to the missionaries. As long as the little island
of St. Helena remained under the government of the East
India Company, spirits, owing to the great injury they had
produced, were not allowed to be imported; but wine was
supplied from the Cape of Good Hope. It is rather a strik-
ing and not very gratifying fact, that in the same year
that spirits were allowed to be sold in Helena, their use was
banished from Tahiti by the free will of the people.

After breakfast we proceeded on our journey. As my ob-
ject was merely to see a little of the interior scenery, we
returned by another track, which descended into the main
valley lower down. For some distance we wound, by a most
intricate path, along the side of the mountain which formed

438 CHARLES DARWIN

the valley. In the less precipitous parts we passed through
extensive groves of the wild banana. The Tahitians, with
their naked, tattooed bodies, their heads ornamented with
flowers, and seen in the dark shade of these groves, would
have formed a fine picture of man inhabiting some primeval
land. In our descent we followed the line of ridges; these
were exceedingly narrow, and for considerable lengths steep
as a ladder; but all clothed with vegetation. The extreme
care necessary in 'poising each step rendered the walk fa-
tiguing. I did not cease to wonder at these ravines and
precipices : when viewing the country from one of the knife-
edged ridges, the point of support was so small, that the
effect was nearly the same as it must be from a balloon. In
this descent we had occasion to use the ropes only once, at
the point where we entered the main valley. We slept under
the same ledge of rock where we had dined the day before :
the night was fine, but from the depth and narrowness of the
gorge, profoundly dark.

Before actually seeing this country, I found it difficult
to understand two facts mentioned by Ellis; namely, that
after the murderous battles of former times, the survivors
on the conquered side retired into the mountains, where a
handful of men could resist a multitude. Certainly half
a dozen men, at the spot where the Tahitian reared the old
tree, could easily have repulsed thousands. Secondly, that
after the introduction of Christianity, there were wild men
who lived in the mountains, and whose retreats were un-
known to the more civilized inhabitants.

November 20th. — In the morning we started early, and
reached Matavai at noon. On the road we met a large party
of noble athletic men, going for wild bananas. I found that
the ship, on account of the difficulty in watering, had moved
to the harbour of Papawa, to which place I immediately
walked. This is a very pretty spot. The cove is surrounded
by reefs, and the water as smooth as in a lake. The
cultivated ground, with its beautiful productions, inter-
spersed with cottages, comes close down to the water's edge.

From the varying accounts which I had read before reach-
ing these islands, I was very anxious to form, from my own
observation, a judgment of their moral state, — although such

THE VOYAGE OF THE BEAGLE 437

judgment would necessarily be very imperfect. First im-
pressions at all times very much depend on one's previously
acquired ideas. My notions were drawn from Ellis's " Poly-
nesian Researches " — an admirable and most interesting
work, but naturally looking at everything under a favourable
point of view; from Beechey's Voyage; and from that of
Kotzebue, which is strongly adverse to the whole missionary
system. He who compares these three accounts will, I think,
form a tolerably accurate conception of the present state of
Tahiti. One of my impressions, which I took from the two
last authorities, was decidedly incorrect; viz., that the Ta-
hitians had become a gloomy race, and lived in fear of the
missionaries. Of the latter feeling I saw no trace, unless,
indeed, fear and respect be confounded under one name.
Instead of discontent being a common feeling, it would be
difficult in Europe to pick out of a crowd half so many merry
and happy faces. The prohibition of the flute and dancing
is inveighed against as wrong and foolish ; — the more than
presbyterian manner of keeping the sabbath is looked at in
a similar light. On these points I will not pretend to offer
any opinion to men who have resided as many years as I
was days on the island.

On the whole, it appears to me that the morality and
religion of the inhabitants are highly creditable. There are
many who attack, even more acrimoniously than Kotzebue,
both the missionaries, their system, and the effects produced
by it. Such reasoners never compare the present state with
that of the island only twenty years ago ; nor even with that
of Europe at this day; but they compare it with the high
standard of Gospel perfection. They expect the missionaries
to effect that which the Apostles themselves failed to do.
Inasmuch as the condition of the people falls short of
this high standard, blame is attached to the missionary, in-
stead of credit for that which he has effected. They forget,
or will not remember, that human sacrifices, and the power
of an idolatrous priesthood — a system of profligacy unparal-
leled in any other part of the world — infanticide a consequence
of that system — bloody wars, where the conquerors spared
neither women nor children — that all these have been abol-
ished; and that dishonesty, intemperance, and licentiousness

438 CHARLES DARWIN

have been greatly reduced by the introduction of Christianity.
In a voyager to forget these things is base ingratitude; for
should he chance to be at the point of shipwreck on some
unknown coast, he will most devoutly pray that the lesson of
the missionary may have extended thus far.

In point of morality, the virtue of the women, it has been
often said, is most open to exception. But before they are
blamed too severely, it will be well distinctly to call to mind
the scenes described by Captain Cook and Mr. Banks, in
which the grandmothers and mothers of the present race
played a part. Those who are most severe, should consider
how much of the morality of the women in Europe is owing
to the system early impressed by mothers on their daughters,
and how much in each individual case to the precepts of re-
ligion. But it is useless to argue against such reasoners; — I
believe that, disappointed in not finding the field of licen-
tiousness quite so open as formerly, they will not give credit
to a morality which they do not wish to practise, or to a
religion which they undervalue, if not despise.

Sunday, 22nd. — The harbour of Papiete, where the queen
resides, may be considered as the capital of the island: it is
also the seat of government, and the chief resort of shipping.
Captain Fitz Roy took a party there this day to hear divine
service, first in the Tahitian language, and afterwards in our
own. Mr. Pritchard, the leading missionary in the island,
performed the service. The chapel consisted of a large airy
framework of wood ; and it was filled to excess by tidy, clean
people, of all ages and both sexes. I was rather disappointed
in the apparent degree of attention; but I believe my ex-
pectations were raised too high. At all events the appear-
ance was quite equal to that in a country church in England.
The singing of the hymns was decidedly very pleasing, but
the language from the pulpit, although fluently delivered, did
not sound well : a constant repetition of words, like " tata
ta, mata mai," rendered it monotonous. After English serv-
ice, a party returned on foot to Matavai. It was a pleasant
walk, sometimes along the sea-beach and sometimes under
the shade of the many beautiful trees.

About two years ago, a small vessel under English colours
was plundered by some of the inhabitants of the Low Islands,

THE VOYAGE OF THE BEAGLE 439

which were then under the dominion of the Queen of Tahiti.
It was believed that the perpetrators were instigated to this
act by some indiscreet laws issued by her majesty. The
British government demanded compensation ; which was ac-
ceded to, and the sum of nearly three thousand dollars was
agreed to be paid on the first of last September. The Com-
modore at Lima ordered Captain Fitz Roy to inquire con-
cerning this debt, and to demand satisfaction if it were not
paid. Captain Fitz Roy accordingly requested an interview
with the Queen Pomarre, since famous from the ill-treatment
she had received from the French; and a parliament was
held to consider the question, at which all the principal chiefs
of the island and the queen were assembled. I will not at-
tempt to describe what took place, after the interesting ac-
count given by Captain Fitz Roy. The money, it appeared,
had not been paid; perhaps the alleged reasons were rather
equivocal ; but otherwise I cannot sufficiently express our
general surprise at the extreme good sense, the reasoning
powers, moderation, candour, and prompt resolution, which
were displayed on all sides. I believe we all left the meeting
with a very different opinion of the Tahitians, from what we
entertained when we entered. The chiefs and people re-
solved to subscribe and complete the sum which was want-
ing; Captain Fitz Roy urged that it was hard that their pri-
vate property should be sacrificed for the crimes of distant
islanders. They replied, that they were grateful for his con-
sideration, but that Pomarre was their Queen, and that they
were determined to help her in this her difficulty. This reso-
lution and its prompt execution, for a book was opened
early the next morning, made a perfect conclusion to this
very remarkable scene of loyalty and good feeling.

After the main discussion was ended, several of the chiefs
took the opportunity of asking Captain Fitz Roy many in-
telligent questions on international customs and laws, relat-
ing to the treatment of ships and foreigners. On some
points, as soon as the decision was made, the law was issued
verbally on the spot. This Tahitian parliament lasted for
several hours; and when it was over Captain Fitz Roy in-
vited Queen Pomarre to pay the Beagle a visit.

November 2$th. — In the evening four boats were sent for

440 CHARLES DARWIN

her majesty; the ship was dressed with flags, and the yards
manned on her coming on board. She was accompanied by
most of the chiefs. The behaviour of all was very proper:
they begged for nothing, and seemed much pleased with Cap-
tain Fitz Roy's presents. The queen is a large awkward
woman, without any beauty, grace or dignity. She has only
one royal attribute: a perfect immovability of expression
under all circumstances, and that rather a sullen one. The
rockets were most admired ; and a deep " Oh ! " could be
heard from the shore, all round the dark bay, after each ex-
plosion. The sailors' songs were also much admired; and
the queen said she thought that one of the most boisterous
ones certainly could not be a hymn ! The royal party did
not return on shore till past midnight.

26th. — In the evening, with a gentle land-breeze, a course
was steered for New Zealand; and as the sun set, we had a
farewell view of the mountains of Tahiti — the island to which
every voyager has offered up his tribute of admiration.

December ipth. — In the evening we saw in the distance
New Zealand. We may now consider that we have nearly
crossed the Pacific. It is necessary to sail over this great
ocean to comprehend its immensity. Moving quickly on-
wards for weeks together, we meet with nothing but the
same blue, profoundly deep, ocean. Even within the archi-
pelagoes, the islands are mere specks, and far distant one
from the other. Accustomed to look at maps drawn on a
small scale, where dots, shading, and names are crowded
together, we do not rightly judge how infinitely small the
proportion of dry land is to water of this vast expanse.
The meridian of the Antipodes has likewise been passed ; and
now every league, it made us happy to think, was one league
nearer to England. These Antipodes call to one's mind old
recollections of childish doubt and wonder. Only the other
day I looked forward to this airy barrier as a definite point
in our voyage homewards; but now I find it, and all such
resting-places for the imagination, are like shadows, which
a man moving onwards cannot catch. A gale of wind last-
ing for some days, has lately given us full leisure to measure
the future stages in our homeward voyage, and to wish
most earnestly for its termination.

441

December 2ist. — Early in the morning we entered the Bay
of Islands, and being becalmed for some hours near the
mouth, we did not reach the anchorage till the middle of the
day. The country is hilly, with a smooth outline, and is
deeply intersected by numerous arms of the sea extending
from the bay. The surface appears from a distance as if
clothed with coarse pasture, but this in truth is nothing but
fern. On the more distant hills, as well as in parts of the
valleys, there is a good deal of woodland. The general tint
of the landscape is not a bright green; and it resembles the
country a short distance to the south of Concepcion in Chile.
In several parts of the bay, little villages of square tidy-look-
ing houses are scattered close down to the water's edge.
Three whaling-ships were lying at anchor, and a canoe every
now and then crossed from shore to shore; with these
exceptions, an air of extreme quietness reigned over the
whole district. Only a single canoe came alongside. This,
and the aspect of the whole scene, afforded a remarkable,
and not very pleasing contrast, with our joyful and boisterous
welcome at Tahiti.

In the afternoon we went on shore to one of the larger
groups of houses, which yet hardly deserves the title of a
village. Its name is Pahia: it is the residence of the mis-
sionaries; and there are no native residents except servants
and labourers. In the vicinity of the Bay of Islands, the
number of Englishmen, including their families, amounts to
between two and three hundred. All the cottages, many of
which are white-washed and look very neat, are the property
of the English. The hovels of the natives are so diminutive
and paltry, that they can scarcely be perceived from a dis-
tance. At Pahia, it was quite pleasing to behold the En-
glish flowers in the gardens before the houses; there were
roses of several kinds, honeysuckle, jasmine, stocks, and
whole hedges of sweetbrier.

December ?2nd. — In the morning I went out walking ; but
I soon found that the country was very impracticable. All
the hills are thickly covered with tall fern, together with
a low bush which grows like a cypress; and very little
ground has been cleared or cultivated. I then tried the
sea-beach; but proceeding towards either hand, my walk

442 CHARLES DARWIN

was soon stopped by salt-water creeks and deep brooks. The
communication between the inhabitants of the different
parts of the bay, is (as in Chiloe) almost entirely kept up
by boats. I was surprised to find that almost every hill which
I ascended, had been at some former time more or less
fortified. The summits were cut into steps or successive
terraces, and frequently they had been protected by deep
trenches. I afterwards observed that the principal hills in-
land in like manner showed an artificial outline. These are
the Pas, so frequently mentioned by Captain Cook under the
name of " hippah ; " the difference of sound being owing to
the prefixed article.

That the Pas had formerly been much used, was evident
from the piles of shells, and the pits in which, as I was
informed, sweet potatoes used to be kept as a reserve. As
there was no water on these hills, the defenders could never
have anticipated a long siege, but only a hurried attack for
plunder, against which the successive terraces would have
afforded good protection. The general introduction of fire-
arms has changed the whole system of warfare; and an ex-
posed situation on the top of a hill is now worse than useless.
The Pas in consequence are, at the present day, always built
on a level piece of ground. They consist of a double stockade
of thick and tall posts, placed in a zigzag line, so that every
part can be flanked. Within the stockade a mound of earth is
thrown up, behind which the defenders can rest in safety, or
use their fire-arms over it. On the level of the ground
little archways sometimes pass through this breastwork,
by which means the defenders can crawl out to the stockade
and reconnoitre their enemies. The Rev. W. Williams, who
gave me this account, added, that in one Pas he had noticed
spurs or buttresses projecting on the inner and protected
side of the mound of earth. On asking the chief the use
of them, he replied, that if two or three of his men were
shot, their neighbours would not see the bodies, and so be
discouraged.

These Pas are considered by the New Zealanders as very
perfect means of defence: for the attacking force is never
so well disciplined as to rush in a body to the stockade, cut
it down, and effect their entry. When a tribe goes to war,

THE VOYAGE OF THE BEAGLE 443

the chief cannot order one party to go here and another
there ; but every man fights in the manner which best pleases
himself; and to each separate individual to approach a stock-
ade defended by fire-arms must appear certain death. I
should think a more warlike race of inhabitants could not
be found in any part of the world than the New Zealanders.
Their conduct on first seeing a ship, as described by Captain
Cook, strongly illustrates this: the act of throwing volleys
of stones at so great and novel an object, and their defiance
of " Come on shore and we will kill and eat you all," shows
uncommon boldness. This warlike spirit is evident in many
of their customs, and even in their smallest actions. If a
New Zealander is struck, although but in joke, the blow
must be returned and of this I saw an instance with one
of our officers.

At the present day, from the progress of civilization, there
is much less warfare, except among some of the southern
tribes. I heard a characteristic anecdote of what took place
some time ago in the south. A missionary found a chief and
his tribe in preparation for war; — their muskets clean and
bright, and their ammunition ready. He reasoned long on
the inutility of the war, and the little provocation which
had been given for it. The chief was much shaken in his
resolution, and seemed in doubt: but at length it occurred
to him that a barrel of his gunpowder was in a bad state, and
that it would not keep much longer. This was brought for-
ward as an unanswerable argument for the necessity of im-
mediately declaring war : the idea of allowing so much good
gunpowder to spoil was not to be thought of; and this set-
tled the point. I was told by the missionaries that in the
life of Shongi, the chief who visited England, the love of
war was the one and lasting spring of every action. The
tribe in which he was a principal chief had at one time been
oppressed by another tribe from the Thames River. A
solemn oath was taken by the men that when their boys
should grow up, and they should be powerful enough, they
would never forget or forgive these injuries. To fulfil this
oath appears to have been Shongi's chief motive for going
to England; and when there it was his sole object. Pres-
ents were valued only as they could be converted into arms ;

444 CHARLES DARWIN

of the arts, those alone interested him which were connected
with the manufacture of arms. When at Sydney, Shongi,
by a strange coincidence, met the hostile chief of the Thames
River at the house of Mr. Marsden : their conduct was civil
to each other; but Shongi told him that when again in New
Zealand he would never cease to carry war into his country.
The challenge was accepted; and Shongi on his return ful-
filled the threat to the utmost letter. The tribe on the
Thames River was utterly overthrown, and the chief to
whom the challenge had been given was himself killed.
Shongi, although harbouring such deep feelings of hatred
and revenge, is described as having been a good-natured
person.

In the evening I went with Captain Fitz Roy and Mr.
Baker, one of the missionaries, to pay a visit to Kororadika :
we wandered about the village, and saw and conversed with
many of the people, both men, women, and children. Look-
ing at the New Zealander, one naturally compares him with
the Tahitian ; both belonging to the same family of mankind.
The comparison, however, tells heavily against the New
Zealander. He may, perhaps be superior in energy, but
in every other respect his character is of a much lower
order. One glance at their respective expressions, brings
conviction to the mind that one is a savage, the other a
civilized man. It would be vain to seek in the whole of
New Zealand a person with the face and mien of the old
Tahitian chief Utamme. No doubt the extraordinary manner
in which tattooing is here practised, gives a disagreeable
expression to their countenances. The complicated but sym-
metrical figures covering the whole face, puzzle and mislead
an unaccustomed eye : it is moreover probable, that the deep
incisions, by destroying the play of the superficial muscles,
give an air of rigid inflexibility. But, besides this, there is
a twinkling in the eye, which cannot indicate anything but
cunning and ferocity. Their figures are tall and bulky; but
not comparable in elegance with those of the working-
classes in Tahiti.

But their persons and houses are filthily dirty and offen-
sive: the idea of washing either their bodies or their clothes
never seems to enter their heads. I saw a chief, who was

THE VOYAGE OF THE BEAGLE 445

wearing a shirt black and matted with filth, and when asked
how it came to be so dirty, he replied, with surprise, " Do
not you see it is an old one? " Some of the men have shirts ;
but the common dress is one or two large blankets, generally
black with dirt, which are thrown over their shoulders in a
very inconvenient and awkward fashion. A few of the prin-
cipal chiefs have decent suits of English clothes; but these
are only worn on great occasions.

December 2$rd. — At a place called Waimate, about fifteen
miles from the Bay of Islands, and midway between the
eastern and western coasts, the missionaries have purchased
some land for agricultural purposes. I had been introduced
to the Rev. W. Williams, who, upon my expressing a wish,
invited me to pay him a visit there. Mr. Bushby, the British
resident, offered to take me in his boat by a creek, where I
should see a pretty waterfall, and by which means my
walk would be shortened. He likewise procured for me a
guide.

Upon asking a neighbouring chief to recommend a man, the
chief himself offered to go; but his ignorance of the value
of money was so complete, that at first he asked how many
pounds I would give him, but afterwards was well contented
with two dollars. When I showed the chief a very small
bundle, which I wanted carried, it became absolutely neces-
sary for him to take a slave. These feelings of pride are
beginning to wear away ; but formerly a leading man would
sooner have died, than undergone the indignity of carrying
the smallest burden. My companion was a light active man,
dressed in a dirty blanket, and with his face completely
tattooed. He had formerly been a great warrior. He ap-
peared to be on very cordial terms with Mr. Bushby ; but at
various times they had quarrelled violently. Mr. Bushby
remarked that a little quiet irony would frequently silence
any one of these natives in their most blustering moments.
This chief has come and harangued Mr. Bushby in a hec-
toring manner, saying, " great chief, a great man, a friend
of mine, has come to pay me a visit — you must give him
something good to eat, some fine presents, etc." Mr. Bushby
has allowed him to finish his discourse, and then has quietly
replied by some answer such as, " What else shall your slave

446 CHARLES DARWIN

do for you?" The man would then instantly, with a very
comical expression, cease his braggadocio.

Some time ago, Mr. Bushby suffered a far more serious
attack. A chief and a party of men tried to break into his
house in the middle of the night, and not finding this so easy,
commenced a brisk firing with their muskets. Mr. Bushby
was slightly wounded, but the party was at length driven
away. Shortly afterwards it was discovered who was the
aggressor ; and a general meeting of the chiefs was convened
to consider the case. It was considered by the New Zealand-
ers as very atrocious, inasmuch as it was a night attack, and
that Mrs. Bushby was lying ill in the house: this latter cir-
cumstance, much to their honour, being considered in all
cases as a protection. The chiefs agreed to confiscate the
land of the aggressor to the King of England. The whole
proceeding, however, in thus trying and punishing a chief
was entirely without precedent. The aggressor, moreover,
lost caste in the estimation of his equals and this was con-
sidered by the British as of more consequence than the con-
fiscation of his land.

As the boat was shoving off, a second chief stepped into
her, who only wanted the amusement of the passage up and
down the creek. I never saw a more horrid and ferocious
expression than this man had. It immediately struck me
I had somewhere seen his likeness : it will be found in
Retzch's outlines to Schiller's ballad of Fridolin, where two
men are pushing Robert into the burning iron furnace. It
is the man who has his arm on Robert's breast. Physiog-
nomy here spoke the truth; this chief had been a notorious
murderer, and was an arrant coward to boot. At the point
where the boat landed, Mr. Bushby accompanied me a few
hundred yards on the road: I could not help admiring the
cool impudence of the hoary old villain, whom we left lying
in the boat, when he shouted to Mr. Bushby, " Do not you
stay long, I shall be tired of waiting here."

We now commenced our walk. The road lay along a
well beaten path, bordered on each side by the tall fern,
which covers the whole country. After travelling some
miles, we came to a little country village, where a few hovels
were collected together, and some patches of ground culti-

THE VOYAGE OF THE BEAGLE 447

vated with potatoes. The introduction of the potato has
been the most essential benefit to the island ; it is now much
more used than any native vegetable. New Zealand is
favoured by one great natural advantage; namely, that the
inhabitants can never perish from famine. The whole
country abounds with fern: and the roots of this plant, if
not very palatable, yet contain much nutriment. A native
can always subsist on these, and on the shell-fish, which are
abundant on all parts of the sea-coast. The villages are
chiefly conspicuous by the platforms which are raised on
four posts ten or twelve feet above the ground, and on
which the produce of the fields is kept secure from all
accidents.

On coming near one of the huts I was much amused by
seeing in due form the ceremony of rubbing, or, as it ought
to be called, pressing noses. The women, on our first ap-
proach, began uttering something in a most dolorous voice ;
they then squatted themselves down and held up their faces ;
my companion standing over them, one after another, placed
the bridge of his nose at right angles to theirs, and com-
menced pressing. This lasted rather longer than a cordial
shake of the hand with us ; and as we vary the force of the
grasp of the hand in shaking, so do they in pressing. Dur-
ing the process they uttered comfortable little grunts, very
much in the same manner as two pigs do, when rubbing
against each other. I noticed that the slave would press
noses with any one he met, indifferently either before or
after his master the chief. Although among the savages, the
chief has absolute power of life and death over his slave,
yet there is an entire absence of ceremony between them.
Mr. Burchell has remarked the same thing in Southern Af-
rica, with the rude Bachapins. Where civilization has
arrived at a certain point, complex formalities soon arise
between the different grades of society: thus at Tahiti all
were formerly obliged to uncover themselves as low as the
waist in presence of the king.

The ceremony of pressing noses having been duly com-
pleted with all present, we seated ourselves in a circle in the
front of one of the novels, and rested there half-an-hour.
All the hovels have nearly the same form and dimensions,

448 CHARLES DARWIN

and all agree in being filthily dirty. They resemble a cow-
shed with one end open, but having a partition a little way
within, with a square hole in it, making a small gloomy
chamber. In this the inhabitants keep all their property,
and when the weather is cold they sleep there. They eat,
however, and pass their time in the open part in front. My
guides having finished their pipes, we continued our walk.
The path led through the same undulating country, the whole
uniformly clothed as before with fern. On our right hand
we had a serpentine river, the banks of which were fringed
with trees, and here and there on the hill sides there was a
clump of wood. The whole scene, in spite of its green col-
our, had rather a desolate aspect. The sight of so much fern
impresses the mind with an idea of sterility : this, however,
is not correct ; for wherever the fern grows thick and breast-
high, the land by tillage becomes productive. Some of the
residents think that all this extensive open country originally
was covered with forests, and that it has been cleared by fire.
It is said, that by digging in the barest spots, lumps of the
kind of resin which flows from the kauri pine are frequently
found. The natives had an evident motive in clearing the
country; for the fern, formerly a staple article of food,
flourishes only in the open cleared tracks. The almost entire
absence of associated grasses, which forms so remarkable a
feature in the vegetation of this island, may perhaps be
accounted for by the land having been aboriginally covered
with forest-trees.

The soil is volcanic; in several parts we passed over
shaggy lavas, and craters could clearly be distinguished on
several of the neighbouring hills. Although the scenery is
nowhere beautiful, and only occasionally pretty, I enjoyed
my walk. I should have enjoyed it more, if my companion,
the chief, had not possessed extraordinary conversational
powers. I knew only three words: "good," "bad," and
" yes : " and with these I answered all his remarks, without
of course having understood one word he said. This, how-
ever, was quite sufficient : I was a good listener, an agreeable
person, and he never ceased talking to me.

At length we reached Waimate. After having passed over
so many miles of an uninhabited useless country, the sudden.

THE VOYAGE OF THE BEAGLE 449

appearance of an English farm-house, and its well-dressed
fields, placed there as if by an enchanter's wand, was exceed-
ingly pleasant. Mr. Williams not being at home, I received
in Mr. Davies's house a cordial welcome. After drinking tea
with his family party, we took a stroll about the farm. At
Waimate there are three large houses, where the missionary
gentlemen, Messrs. Williams, Davies, and Clarke, reside;
and near them are the huts of the native labourers. On an
adjoining slope, fine crops of barley and wheat were standing
in full ear ; and in another part, fields of potatoes and clover.
But I cannot attempt to describe all I saw ; there were large
gardens, with every fruit and vegetable which England pro-
duces; and many belonging to a warmer clime. I may
instance asparagus, kidney beans, cucumbers, rhubarb, apples,
pears, figs, peaches, apricots, grapes, olives, gooseberries,
currants, hops, gorse for fences, and English oaks ; also many
kinds of flowers. Around the farm-yard there were stables,
a thrashing-barn with its winnowing machine, a blacksmith's
forge, and on the ground ploughshares and other tools : in
the middle was that happy mixture of pigs and poultry, lying
comfortably together, as in every English farm-yard. At the
distance of a few hundred yards, where the water of a little
rill had been dammed up into a pool, there was a large and
substantial water-mill.

All this is very surprising, when it is considered that five
years ago nothing but the fern flourished here. Moreover,
native workmanship, taught by the missionaries, has effected
this change; — the lesson of the missionary is the enchanter's
wand. The house had been built, the windows framed, the
fields ploughed, and even the trees grafted, by a New Zea-
lander. At the mill, a New Zealander was seen powdered
white with flower, like his brother miller in England. When
I looked at this whole scene, I thought it admirable. It was
not merely that England was brought vividly before my
mind; yet, as the evening drew to a close, the domestic
sounds, the fields of corn, the distant undulating country
with its trees might well have been mistaken for our father-
land : nor was it the triumphant feeling at seeing what Eng-
lishmen could effect ; but rather the high hopes thus inspired
for the future progress of this fine island.

Several young men, redeemed by the missionaries from
slavery, were employed on the farm. They were dressed in
a shirt, jacket, and trousers, and had a respectable appear-
ance. Judging from one trifling anecdote, I should think
they must be honest. When walking in the fields, a young
labourer came up to Mr. Davies, and gave him a knife and
gimlet, saying that he had found them on the road, and did
not know to whom they belonged! These young men and
boys appeared very merry and good-humoured. In the even-
ing I saw a party of them at cricket: when I thought of the
austerity of which the missionaries have been accused, I was
amused by observing one of their own sons taking an active
part in the game. A more decided and pleasing change was
manifested in the young women, who acted as servants within
the houses. Their clean, tidy, and healthy appearance, like
that of the dairy-maids in England, formed a wonderful
contrast with the women of the filthy hovels in Kororadika.
The wives of the missionaries tried to persuade them not to
be tattooed; but a famous operator having arrived from the
south, they said, " We really must just have a few lines on
our lips ; else when we grow old, our lips will shrivel, and we
shall be so very ugly." There is not nearly so much tattooing
as formerly; but as it is a badge of distinction between the
chief and the slave, it will probably long be practised. So
soon does any train of ideas become habitual, that the mis-
sionaries told me that even in their eyes a plain face looked
mean, and not like that of a New Zealand gentleman.

Late in the evening I went to Mr. Williams's house, where
I passed the night. I found there a large party of children,
collected together for Christmas Day, and all sitting round
a table at tea. I never saw a nicer or more merry group ; and
to think that this was in the centre of the land of cannibal-
ism, murder, and all atrocious crimes! The cordiality and
happiness so plainly pictured in the faces of the little circle,
appeared equally felt by the older persons of the mission.

December 24th. — In the morning, prayers were read in
the native tongue to the whole family. After breakfast I
rambled about the gardens and farm. This was a market-
day, when the natives of the surrounding hamlets bring their
potatoes, Indian corn, or pigs, to exchange for blankets,

THE VOYAGE OF THE BEAGLE 451

tobacco, and sometimes, through the persuasions of the mis-
sionaries, for soap. Mr. Davies's eldest son, who manages a
farm of his own, is the man of business in the market. The
children of the missionaries, who came while young to the
island, understand the language better than their parents,
and can get anything more readily done by the natives.

A little before noon Messrs. Williams and Davies walked
with me to a part of a neighbouring forest, to show me the
famous kauri pine. I measured one of the noble trees, and
found it thirty-one feet in circumference above the roots.
There was another close by, which I did not see, thirty-three
feet ; and I heard of one no less than forty feet. These trees
are remarkable for their smooth cylindrical boles, which run
up to a height of sixty, and even ninety feet, with a nearly
equal diameter, and without a single branch. The crown
of branches at the summit is out of all proportion small to
the trunk; and the leaves are likewise small compared with
the branches. The forest was here almost composed of the
kauri; and the largest trees, from the parallelism of their
sides, stood up like gigantic columns of wood. The timber
of the kauri is the most valuable production of the island;
moreover, a quantity of resin oozes from the bark, which is
sold at a penny a pound to the Americans, but its use was
then unknown. Some of the New Zealand forest must be
impenetrable to an extraordinary degree. Mr. Matthew
informed me that one forest only thirty-four miles in wf 1th,
and separating two inhabited districts, had only lately, for
the first time, been crossed. He and another missionary,
each with a party of about fifty men, undertook to open a
road; but it cost more than a fortnight's labour! In
the woods I saw very few birds. With regard to animals,
it is a most remarkable fact, that so large an island, extend-
ing over more than 700 miles in latitude, and in many parts
ninety broad, with varied stations, a fine climate, and land
of all heights, from 14,000 feet downwards, with the excep-
tion of a small rat, did not possess one indigenous animal.
The several species of that gigantic genus of birds, the Dei-
nornis seem here to have replaced mammiferous quadrupeds,
in the same manner as the reptiles still do at the Galapagos
archipelago. It is said that the common Norway rat, in

452 CHARLES DARWIN

the short space of two years, annihilated in this northern
end of the island, the New Zealand species. In many places
I noticed several sorts of weeds, which, like the rats, I was
forced to own as countrymen. A leek has overrun whole
districts, and will prove very troublesome, but it was im-
ported as a favour by a French vessel. The common dock
is also widely disseminated, and will, I fear, for ever remain
a proof of the rascality of an Englishman, who sold the seeds
for those of the tobacco plant.

On returning from our pleasant walk to the house, I dined
with Mr. Williams; and then, a horse being lent me, I re-
turned to the Bay of Islands. I took leave of the missionaries
with thankfulness for their kind welcome, and with feel-
ings of high respect for their gentlemanlike, useful, and
upright characters. I think it would be difficult to find
a body of men better adapted for the high office which
they fulfil.

Christmas Day. — In a few more days the fourth year of
our absence from England will be completed. Our first
Christmas Day was spent at Plymouth; the second at St.
Martin's Cove, near Cape Horn; the third at Port Desire,
in Patagonia; the fourth at anchor in a wild harbour in the
peninsula of Tres Montes; this fifth here; and the next, I
trust in Providence, will be in England. We attended divine
service in the chapel of Pahia; part of the service being
read in English, and part in the native language. Whilst at
New Zealand we did not hear of any recent acts of canni-
balism; but Mr. Stokes found burnt human bones strewed
round a fire-place on a small island near the anchorage ; but
these remains of a comfortable banquet might have been
lying there for several years. It is probable that the moral
state of the people will rapidly improve. Mr. Bushby men-
tioned one pleasing anecdote as a proof of the sincerity of
some, at least, of those who profess Christianity. One of
his young men left him, who had been accustomed to read
prayers to the rest of the servants. Some weeks afterwards,
happening to pass late in the evening by an outhouse, he saw
and heard one of his men reading the Bible with difficulty
by the light of the fire, to the others. After this the party
knelt and prayed: in their prayers they mentioned Mr.

THE VOYAGE OF THE BEAGLE 453

Bushby and his family, and the missionaries, each separately
in his respective district.

December 26th. — Mr. Bushby offered to take Mr. Sulivan
and myself in his boat some miles up the river to Cawa-
Cawa; and proposed afterwards to walk on to the village of
Waiomio, where there are some curious rocks. Following
one of the arms of the bay, we enjoyed a pleasant row, and
passed through pretty scenery, until we came to a village,
beyond which the boat could not pass. From this place a
chief and a party of men volunteered to walk with us to
Waiomio, a distance of four miles. The chief was at this
time rather notorious from having lately hung one of his
wives and a slave for adultery. When one of the mission-
aries remonstrated with him he seemed surprised, and said
he thought he was exactly following the English method.
Old Shongi, who happened to be in England during the
Queen's trial, expressed great disapprobation at the whole
proceeding: he said he had five wives, and he would rather
cut off all their heads than be so much troubled about one.
Leaving this village, we crossed over to another, seated on
a hill-side at a little distance. The daughter of a chief, who
was still a heathen, had died there five days before. The
hovel in which she had expired had been burnt to the ground :
her body being enclosed between two small canoes, was
placed upright on the ground, and protected by an enclosure
bearing wooden images of their gods, and the whole was
painted bright red, so as to be conspicuous from afar. Her
gown was fastened to the coffin, and her hair being cut off
was cast at its foot. The relatives of the family had torn
the flesh of their arms, bodies, and faces, so that they were
covered with clotted blood; and the old women looked most
filthy, disgusting objects. On the following day some of the
officers visited this place, and found the women still howling
and cutting themselves.

We continued our walk, and soon reached Waiomio. Here
there are some singular masses of limestone, resembling
ruined castles. These rocks have long served for burial
places, and in consequence are held too sacred to be ap-
proached. One of the young men, however, cried out, " Let
us all be brave," and ran on ahead ; but when within a hun-

454 CHARLES DARWIN

dred yards, the whole party thought better of it, and stopped
short. With perfect indifference, however, they allowed us
to examine the whole place. At this village we rested some
hours, during which time there was a long discussion with
Mr. Bushby, concerning the right of sale of certain lands.
One old man, who appeared a perfect genealogist, illustrated
the successive possessors by bits of stick driven into the
ground. Before leaving the houses a little basketful of
roasted sweet potatoes was given to each of our party; and
we all, according to the custom, carried them away to eat
on the road. I noticed that among the women employed in
cooking, there was a man-slave : it must be a humiliating
thing for a man in this warlike country to be employed in
doing that which is considered as the lowest woman's work.
Slaves are not allowed to go to war; but this perhaps can
hardly be considered as a hardship. I heard of one poor
wretch who, during hostilities, ran away to the opposite
party; being met by two men, he was immediately seized;
but as they could not agree to whom he should belong, each
stood over him with a stone hatchet, and seemed determined
that the other at least should not take him away alive. The
poor man, almost dead with fright, was only saved by the
address of a chief's wife. We afterwards enjoyed a pleasant
walk back to the boat, but did not reach the ship till late in
the evening.

December joth. — In the afternoon we stood out of the
Bay of Islands, on our course to Sydney. I believe we were
all glad to leave New Zealand. It is not a pleasant place.
Amongst the natives there is absent that charming simplicity
which is found in Tahiti ; and the greater part of the English
are the very refuse of society. Neither is the country itself
attractive. I look back but to one bright spot, and that is
Waimate, with its Christian inhabitants.

/4NUARY 1 2th, 1836. — Early in the morning a light air
carried us towards the entrance of Port Jackson. In-
stead of beholding a verdant country, interspersed with
fine houses, a straight line of yellowish cliff brought to our
minds the coast of Patagonia. A solitary lighthouse, built of
white stone, alone told us that we were near a great and
populous city. Having entered the harbour, it appears fine
and spacious, with cliff-formed shores of horizontally strati-
fied sandstone. The nearly level country is covered with thin
scrubby trees, bespeaking the curse of sterility. Proceeding
further inland, the country improves: beautiful villas and
nice cottages are here and there scattered along the beach.
In the distance stone houses, two and three stories high, and
windmills standing on the edge of a bank, pointed out to us
the neighbourhood of the capital of Australia.

At last we anchored within Sydney Cove. We found the
little basin occupied by many large ships, and surrounded by
warehouses. In the evening I walked through the town, and
returned full of admiration at the whole scene. It is a most
magnificent testimony to the power of the British nation.
Here, in a less promising country, scores of years have done
many more times more than an equal number of centuries
have effected in South America. My first feeling was to
congratulate myself that I was born an Englishman. Upon

455

456 CHARLES DARWIN

seeing more of the town afterwards, perhaps my admiration
fell a little ; but yet it is a fine town. The streets are regular,
broad, clean, and kept in excellent order ; the houses are of a
good size, and the shops well furnished. It may be faithfully
compared to the large suburbs which stretch out from London
and a few other great towns in England ; but not even near
London or Birmingham is there an appearance of such rapid
growth. The number of large houses and other buildings just
finished was truly surprising; nevertheless, every one com-
plained of the high rents and difficulty in procuring a house.
Coming from South America, where in the towns every man
of property is known, no one thing surprised me more than
not being able to ascertain at once to whom this or that car-
riage belonged.

I hired a man and two horses to take me to Bathurst, a
village about one hundred and twenty miles in the interior,
and the centre of a great pastoral district. By this means I
hoped to gain a general idea of the appearance of the country.
On the morning of the i6th (January) I set out on my excur-
sion. The first stage took us to Paramatta, a small country
town, next to Sydney in importance. The roads were excel-
lent, and made upon the MacAdam principle, whinstone hav-
ing been brought for the purpose from the distance of several
miles. In all respects there was a close resemblance to Eng-
land: perhaps the alehouses here were more numerous. The
iron gangs, or parties of convicts who have committed here
some offense, appeared the least like England: they were
working in chains, under the charge of sentries with loaded
arms.

The power which the government possesses, by means
of forced labour, of at once opening good roads throughout
the country, has been, I believe, one main cause of the early
prosperity of this colony. I slept at night at a very com-
fortable inn at Emu ferry, thirty-five miles from Sydney,
and near the ascent of the Blue Mountains. This line of
road is the most frequented, and has been the longest in-
habited of any in the colony. The whole land is enclosed
with high railings, for the farmers have not succeeded in
rearing hedges. There are many substantial houses and good
cottages scattered about ; but although considerable pieces of

THE VOYAGE OF THE BEAGLE 457

land are under cultivation, the greater part yet remains as
when first discovered.

The extreme uniformity of the vegetation is the most
remarkable feature in the landscape of the greater part of
New South Wales. Everywhere we have an open woodland,
the ground being partially covered with a very thin pasture,
with little appearance of verdure. The trees nearly all
belong to one family, and mostly have their leaves placed in
a vertical, instead of, as in Europe, in a nearly horizontal
position : the foliage is scanty, and of a peculiar pale green
tint; without any gloss. Hence the woods appear light and
shadowless : this, although a loss of comfort to the traveller
under the scorching rays of summer, is of importance to the
farmer, as it allows grass to grow where it otherwise would
not. The leaves are not shed periodically : this character
appears common to the entire southern hemisphere, namely,
South America, Australia, and the Cape of Good Hope. The
inhabitants of this hemisphere, and of the intertropical
regions, thus lose perhaps one of the most glorious, though
to our eyes common, spectacles in the world — the first burst-
ing into full foliage of the leafless treet They may, however,
say that we pay dearly for this by having the land covered
with mere naked skeletons for so many months. This is too
true; but our senses thus acquire a keen relish for the ex-
quisite green of the spring, which the eyes of those living
within the tropics, sated during the long year with the gor-
geous productions of those glowing climates, can never ex-
perience. The greater number of the trees, with the excep-
tion of some of the Blue-gums, do not attain a large size;
but they grow tall and tolerably straight, and stand well
apart. The bark of some of the Eucalypti falls annually, or
hangs dead in long shreds which swing about with the wind,
and give to the woods a desolate and untidy appearance. I
cannot imagine a more complete contrast, in every respect,
than between the forests of Valdivia or Chiloe, and the
woods of Australia.

At sunset, a party of a score of the black aborigines passed
by, each carrying, in their accustomed manner, a bundle of
spears and other weapons. By giving a leading young man a
shilling, they were easily detained, and threw their spears for

45& CHARLES DARWIN

my amusement. They were all partly clothed, and several
could speak a little English : their countenances were good-
humoured and pleasant, and they appeared far from being
such utterly degraded beings as they have usually been repre-
sented. In their own arts they are admirable. A cap being
fixed at thirty yards distance, they transfixed it with a spear,
delivered by the throwing-stick with the rapidity of an arrow
from the bow of a practised archer. In tracking animals or
men they show most wonderful sagacity ; and I heard of sev-
eral of their remarks which manifested considerable acute-
ness. They will not, however, cultivate the ground, or build
houses and remain stationary, or even take the trouble of
tending a flock of sheep when given to them. On the whole
they appear to me to stand some few degrees higher in the
scale of civilization than the Fuegians.

It is very curious thus to see in the midst of a civilized
people, a set of harmless savages wandering about without
knowing where they shall sleep at night, and gaining their
livelihood by hunting in the woods. As the white man has
travelled onwards, he has spread over the country belonging
to several tribes. These, although thus enclosed by one com-
mon people, keep up their ancient distinctions, and some-
times go to war with each other. In an engagement which
took place lately, the two parties most singularly chose the
centre of the village of Bathurst for the field of battle. This
was of service to the defeated side, for the runaway warriors
took refuge in the barracks.

The number of aborigines is rapidly decreasing. In my
whole ride, with the exception of some boys brought up by
Englishmen, I saw only one other party. This decrease, no
doubt, must be partly owing to the introduction of spirits, to
European diseases (even the milder ones of which, such as
the measles,1 prove very destructive), and to the gradual
extinction of the wild animals. It is said that numbers of
their children invariably perish in very early infancy from
the effects of their wandering life; and as the difficulty of

1 It is remarkable how the same disease is modified in different climates.
At the little island of St. Helena the introduction of scarlet fever is dreaded
as a plague. In some countries, foreigners and natives are as differently
affected by certain contagious disorders as if they had been different ani-
mals; of which fact some instances have occurred in Chile; and, according
to Humboldt, in Mexico (Polit. Essay, New Spain, vol. iv.).

THE VOYAGE OF THE BEAGLE 459

procuring food increases, so must their wandering habits
increase; and hence the population, without any apparent
deaths from famine, is repressed in a manner extremely
sudden compared to what happens in civilized countries,
where the father, though in adding to his labour he may in-
jure himself, does not destroy his offspring.

Besides the several evident causes of destruction, there
appears to be some more mysterious agency generally at
work. Wherever the European has trod, death seems to pur-
sue the aboriginal. We may look to the wide extent of the
Americas, Polynesia, the Cape of Good Hope, and Australia,
and we find the same result. Nor is it the white man alone
that thus acts the destroyer ; the Polynesian of Malay extrac-
tion has in parts of the East Indian archipelago, thus driven
before him the dark-coloured native. The varieties of man
seem to act on each other in the same way as different species
of animals — the stronger always extirpating. the weaker. It
was melancholy at New Zealand to hear the fine energetic
natives saying, that they knew the land was doomed to pass
from their children. Every one has heard of the inexplicable
reduction of the population in the beautiful and healthy island
of Tahiti since the date of Captain Cook's voyages : although
in that case we might have expected that it would have been
increased; for infanticide, which formerly prevailed to so
extraordinary a degree, has ceased; profligacy has greatly
diminished, and the murderous wars become less frequent.

The Rev. J. Williams, in his interesting work8, says, that
the first intercourse between natives and Europeans, " is in-
variably attended with the introduction of fever, dysentery,
or some other disease, which carries off numbers of the peo-
ple." Again he affirms, " It is certainly a fact, which cannot
be controverted, that most of the diseases which have raged
in the islands during my residence there, have been intro-
duced by ships;3 and what renders this fact remarkable is,

3 Narrative of Missionary Enterprise, p. 282.

f Captain Beechey (chap, iv., vol. i.) states that the inhabitants of Pit-
cairn Island are firmly convinced that after the arrival of every ship they
suffer cutaneous and other disorders. Captain Beechey attributes this to
the change of diet during the time of the visit. Dr. Macculloch (Western
Isles, vol. ji. p. 32) says: " It is asserted, that on the arrival of a stranger
(at St. Kilda) all the inhabitants, in the common phraseology, catch a
cold." Dr. Macculloch considers the whole case, although often previously
affirmed, as ludicrous. He adds, however, that " the question was put by

460 CHARLES DARWIN

that there might be no appearance of disease among the crew
of the ship which conveyed this destructive importation."
This statement is not quite so extraordinary as it at first
appears; for several cases are on record of the most malig-
nant fevers having broken out, although the parties them-
selves, who were the cause, were not affected. In the early
part of the reign of George III., a prisoner who had been
confined in a dungeon, was taken in a coach with four con-
stables before a magistrate ; and although the man himself
was not ill, the four constables died from a short putrid
fever; but the contagion extended to no others. From these
facts it would almost appear as if the effluvium of one set
of men shut up for some time together was poisonous when
inhaled by others; and possibly more so, if the men be of
different races. Mysterious as this circumstance appears to
be, it is not more surprising than that the body of one's
fellow-creature, directly after death, and before putrefaction
has commenced, should often be of so deleterious a quality,
that the mere puncture from an instrument used in its dis-
section, should prove fatal.

ifth. — Early in the morning we passed the Nepean in a
ferry-boat. The river, although at this spot both broad and
deep, had a very small body of running water. Having
crossed a low piece of land on the opposite side, we reached
the slope of the Blue Mountains. The ascent is not steep,
the road having been cut with much care on the side of a
sandstone cliff. On the summit an almost level plain extends,
which, rising imperceptibly to the westward, at last attains
a height of more than 3000 feet. From so grand a title as
Blue Mountains, and from their absolute altitude, I expected
to have seen a bold chain of mountains crossing the coun-

us to the inhabitants who unanimously agreed in the story." In Vancou-
ver's Voyage, there is a somewhat similar statement with respect to Otaheite.
Dr. Dieffenbach, in a note to his translation of this Journal, states that the
same fact is universally believed by the inhabitants of the Chatham Islands,
and in parts of New Zealand. It is impossible that such a belief should
have become universal in the northern hemisphere, at the Antipodes, and
in the Pacific, without some good foundation. Humboldt (Polit. Essay on
King of New Spain, vol. iv.) says, that the great epidemics of Panama and
Callao are " marked " by the arrival of ships from Chile, because the people
from that temperate region, first experience the fatal effects of the torrid
zones. I may add, that I have heard it stated in Shropshire, that sheep,
which have been imported from vessels, although themselves in a healthy
condition, if placed in the same fold with others, frequently produce sick-
ness in the flock.

THE VOYAGE OF THE BEAGLE 461

try; but instead of this, a sloping plain presents merely an
inconsiderable front to the low land near the coast. From
this first slope, the view of the extensive woodland to the
east was striking, and the surrounding trees grew bold and
lofty. But when once on the sandstone platform, the scenery
becomes exceedingly monotonous; each side of the road is
bordered by scrubby trees of the never-failing Eucalyptus
family; and with the exception of two or three small inns,
there are no houses or cultivated land: the road, moreover,
is solitary; the most frequent object being a bullock-waggon,
piled up with bales of wool.

In the middle of the day we baited our horses at a little
inn, called the Weatherboard. The country here is elevated
2800 feet above the sea. About a mile and a half from this
place there is a view exceedingly well worth visiting. Fol-
lowing down a little valley and its tiny rill of water, an
immense gulf unexpectedly opens through the trees which
border the pathway, at the depth of perhaps 1500 feet.
Walking on a few yards, one stands on the brink of a vast
precipice, and below one sees a grand bay or gulf, for I know
not what other name to give it, thickly covered with forest.
The point of view is situated as if at the head of a bay, the
line of cliff diverging on each side, and showing headland
behind headland, as on a bold sea-coast. These cliffs are
composed of horizontal strata of whitish sandstone; and
are so absolutely vertical, that in many places a person
standing on the edge and throwing down a stone, can see it
strike the trees in the abyss below. So unbroken is the line
of cliff, that in order to reach the foot of the waterfall,
formed by this little stream, it is said to be necessary to go
sixteen miles round. About five miles distant in front,
another line of cliff extends, which thus appears completely
to encircle the valley; and hence the name of bay is justified,
as applied to this grand amphitheatrical depression. If we
imagine a winding harbour, with its deep water surrounded
by bold cliff-like shores, to be laid dry, and a forest to spring
up on its sandy bottom, we should then have the appearance
and structure here exhibited. This kind of view was to me
quite novel, and extremely magnificent.

In the evening we reached the Blackheath. The sand'

462 CHARLES DARWIN

stone plateau has here attained the height of 3400 feet; and
is covered, as before, with the same scrubby woods. From
the road, there were occasional glimpses into a profound
valley, of the same character as the one described ; but from
the steepness and depth of its sides, the bottom was scarcely
ever to be seen. The Blackheath is a very comfortable inn,
kept by an old soldier ; and it reminded me of the small inns
in North Wales.

i8th. — Very early in the morning, I walked about three
miles to see Govett's Leap; a view of a similar character
with that near the Weatherboard, but perhaps even more
stupendous. So early in the day the gulf was filled with a
thin blue haze, which, although destroying the general effect
of the view added to the apparent depth at which the forest
was stretched out beneath our feet. These valleys, which so
long presented an insuperable barrier to the attempts of the
most enterprising of the colonists to reach the interior, are
most remarkable. Great arm-like bays, expanding at their
upper ends, often branch from the main valleys and pen-
etrate the sandstone platform; on the other hand, the plat-
form often sends promontories into the valleys, and even
leaves in them great, almost insulated, masses. To descend
into some of these valleys, it is necessary to go round twenty
miles; and into others, the surveyors have only lately pen-
etrated, and the colonists have not yet been able to drive in
their cattle. But the most remarkable feature in their struc-
ture is, that although several miles wide at their heads, they
generally contract towards their mouths to such a degree
as to become impassable. The Surveyor-General, Sir T.
Mitchell,* endeavoured in vain, first walking and then by
crawling between the great fallen fragments of sandstone,
to ascend through the gorge by which the river Grose joins
the Nepean; yet the valley of the Grose in its upper part,
as I saw, forms a magnificent level basin some miles in
width, and is on all sides surrounded by cliffs, the summits
of which are believed to be nowhere less than 3000 feet
above the level of the sea. When cattle are driven into the
valley of the Wolgan by a path (which I descended), partly

* Travels in Australia, vol. i. p. 154. I must express my obligation to
Sir T. Mitchell, for several interesting personal communications on the
subject of these great valleys of New Soutn Wales.

THE VOYAGE OF THE BEAGLE 463

natural and partly made by the owner of the land, they can-
not escape ; for this valley is in every other part surrounded
by perpendicular cliffs, and eight miles lower down, it con-
tracts from an average width of half a mile, to a mere
chasm, impassable to man or beast. Sir T. Mitchell states
that the great valley of the Cox river with all its branches,
contracts, where it unites with the Nepean, into a gorge
2200 yards in width, and about 1000 feet in depth. Other
similar cases might have been added.

The first impression, on seeing the correspondence of the
horizontal strata on each side of these valleys and great
amphitheatrical depressions, is that they have been hollowed
out, like other valleys, by the action of water ; but when one
reflects on the enormous amount of stone, which on this
view must have been removed through mere gorges or
chasms, one is led to ask whether these spaces may not have
subsided. But considering the form of the irregularly
branching valleys, and of the narrow promontories projecting
into them from the platforms, we are compelled to abandon
this notion. To attribute these hollows to the present allu-
vial action would be preposterous; nor does the drainage
from the summit-level always fall, as I remarked near the
Weatherboard, into the head of these valleys, but into one
side of their bay-like recesses. Some of the inhabitants re-
marked to me that they never viewed one of those bay-like
recesses, with the headlands receding on both hands, without
being struck with their resemblance to a bold sea-coast. This
is certainly the case; moreover, on the present coast of New
South Wales, the numerous, fine, widely-branching harbours,
which are generally connected with the sea by a narrow
mouth worn through the sandstone coast-cliffs, varying from
one mile in width to a quarter of a mile, present a likeness,
though on a miniature scale, to the great valleys of the
interior. But then immediately occurs the startling difficulty,
why has the sea worn out these great, though circumscribed
depressions on a wide platform, and left mere gorges at the
openings, through which the whole vast amount of triturated
matter must have been carried away? The only light I can
throw upon this enigma, is by remarking that banks of the
most irregular forms appear to be now forming in some seas,

464 CHARLES DARWIN

as in parts of the West Indies and in the Red Sea, and that
their sides are exceedingly steep. Such banks, I have been
led to suppose, have been formed by sediment heaped by
strong currents on an irregular bottom. That in some cases
the sea, instead of spreading out sediment in a uniform sheet,
heaps it round submarine rocks and islands, it is hardly pos-
sible to doubt, after examining the charts of the West Indies;
and that the waves have power to form high and precipitous
cliffs, even in land-locked harbours, I have noticed in many
parts of South America. To apply these ideas to the sand-
stone platforms of New South Wales, I imagine that the
strata were heaped by the action of strong currents, and of
the undulations of an open sea, on an irregular bottom ; and
that the valley-like spaces thus left unfilled had their steeply
sloping flanks worn into cliffs, during a slow elevation of
the land; the worn-down sandstone being removed, either at
the time when the narrow gorges were cut by the retreating
sea, or subsequently by alluvial action.

Soon after leaving the Blackheath, we descended from the
sandstone platform by the pass of Mount Victoria. To effect
this pass, an enormous quantity of stone has been cut
through; the design, and its manner of execution, being
worthy of any line of road in England. We now entered
upon a country less elevated by nearly a thousand feet, and
consisting of granite. With the change of rock, the vegeta-
tion improved; the trees were both finer and stood farther
apart ; and the pasture between them was a little greener and
more plentiful. At Hassan's Walls, I left the high road,
and made a short detour to a farm called Walerawang; to
the superintendent of which I had a letter of introduction
from the owner in Sydney. Mr. Browne had the kindness to
ask me to stay the ensuing day, which I had much pleasure
in doing. This place offers an example of one of the large
farming, or rather sheep-grazing establishments of the
colony. Cattle and horses are, however, in this case rather
more numerous than usual, owing to some of the valleys
being swampy and producing a coarser pasture. Two or
three flat pieces of ground near the house were cleared and
cultivated with corn, which the harvest-men were now reap-

THE VOYAGE OF THE BEAGLE 465

ing: but no more wheat is sown than sufficient for the annual
support of the labourers employed on the establishment. The
usual number of assigned convict-servants here is about
forty, but at the present time there were rather more. Al-
though the farm was well stocked with every necessary,
there was an apparent absence of comfort; and not one
single woman resided here. The sunset of a fine day will
generally cast an air of happy contentment on any scene;
but here, at this retired farm-house, the brightest tints on
the surrounding woods could not make me forget that forty
hardened, profligate men were ceasing from their daily
labours, like the slaves from Africa, yet without their holy
claim for compassion.

Early on the next morning, Mr. Archer, the joint superin-
tendent, had the kindness to take me out kangaroo-hunting.
We continued riding the greater part of the day, but had
very bad sport, not seeing a kangaroo, or even a wild dog.
The greyhounds pursued a kangaroo rat into a hollow tree,
out of which we dragged it: it is an animal as large as a
rabbit, but with the figure of a kangaroo. A few years since
this country abounded with wild animals; but now the emu
is banished to a long distance, and the kangaroo is become
scarce; to both the English greyhound has been highly de-
structive. It may be long before these animals are altogether
exterminated, but their doom is fixed. The aborigines are
always anxious to borrow the dogs from the farm-houses:
the use of them, the offal when an animal is killed, and some
milk from the cows, are the peace-offerings of the settlers,
who push farther and farther towards the interior. The
thoughtless aboriginal, blinded by these trifling advantages,
is delighted at the approach of the white man, who seems
predestined to inherit the country of his children.

Although having poor sport, we enjoyed a pleasant ride.
The woodland is generally so open that a person on horse-
back can gallop through it. It is traversed by a few flat-
bottomed valleys, which are green and free from trees: in
such spots the scenery was pretty like that of a park. In the
whole country I scarcely saw a place without the marks of a
fire; whether these had been more or less recent — whether
the stumps were more or less black, was the greatest change

466 CHARLES DARWIN

which varied the uniformity, so wearisome to the traveller's
eye. In these woods there are not many birds; I saw, how-
ever, some large flocks of the white cockatoo feeding in a
corn-field, and a few most beautiful parrots ; crows, like our
jackdaws were not uncommon, and another bird something
like the magpie. In the dusk of the evening I took a stroll
along a chain of ponds, which in this dry country represented
the course of a river, and had the good fortune to see several
of the famous Ornithorhynchus paradoxus. They were
diving and playing about the surface of the water, but
showed so little of their bodies, that they might easily have
been mistaken for water-rats. Mr. Browne shot one: cer-
tainly it is a most extraordinary animal; a stuffed specimen
does not at all give a good idea of the appearance of the
head and beak when fresh; the latter becoming hard and
contracted.5

20th. — A long day's ride to Bathurst. Before joining the
highroad we followed a mere path through the forest; and
the country, with the exception of a few squatters' huts, was
very solitary. We experienced this day the sirocco-like wind
of Australia, which comes from the parched deserts of the
interior. Clouds of dust were travelling in every direction;
and the wind felt as if it had passed over a fire. I after-
wards heard that the thermometer out of doors had stood at
119°, and in a closed room at 96°. In the afternoon we came
in view of the downs of Bathurst. These undulating but
nearly smooth plains are very remarkable in this country,
from being absolutely destitute of trees. They support only
a thin brown pasture. We rode some miles over this coun-
try, and then reached the township of Bathurst, seated in the
middle of what may be called either a very broad valley, or
narrow plain. I was told at Sydney not to form too bad an
opinion of Australia by judging of the country from the road-
side, nor too good a one from Bathurst ; in this latter respect,

5 1 was interested by finding here the hollow conical pitfall of the lion-
ant, or some other insect; first a fly fell down the treacherous slope and
immediately disappeared; then came a large but unwary ant; its struggles
to escape being very violent, those curious little jets of sand, described by
Kirby and Spence (Entomol., vol. i. p. 425) as being flirted by the insect's
tail, were promptly directed against the expected victim. But the ant
enjoyed a better fate than the fly, and escaped the fatal jaws which lay
concealed at the base of the conical hollow. This Australian pitfall was
only about half the size of that made by the European lion-ant.

THE VOYAGE OF THE BEAGLE 467

I did not feel myself in the least danger of being preju-
diced. The season, it must be owned, had been one of great
drought, and the country did not wear a favourable aspect;
although I understand it was incomparably worse two or
three months before. The secret of the rapidly growing
prosperity of Bathurst is, that the brown pasture which
appears to the stranger's eye so wretched, is excellent for
sheep-grazing. The town stands, at the height of 2200 feet
above the sea, on the banks of the Macquarie. This is one of
the rivers flowing into the vast and scarcely known interior.
The line of watershed, which divides the inland streams from
those on the coast, has a height of about 3000 feet, and runs
in a north and south direction at the distance of from eighty
to a hundred miles from the sea-side. The Macquarie figures
in the map as a respectable river, and it is the largest of
those draining this part of the water-shed ; yet to my surprise
I found it a mere chain of ponds, separated from each other
by spaces almost dry. Generally a small stream is running;
and sometimes there are high and impetuous floods. Scanty
as the supply of the water is throughout this district, it
becomes still scantier further inland.

22nd. — I commenced my return, and followed a new road
called Lockyer's Line, along which the country is rather more
hilly and picturesque. This was a long day's ride; and the
house where I wished to sleep was some way off the road,
and not easily found. I met on this occasion, and indeed on
all others, a very general and ready civility among the lower
orders, which, when one considers what they are, and what
they have been, would scarcely have been expected. The
farm where I passed the night, was owned by two young
men who had only lately come out, and were beginning a
settler's life. The total want of almost every comfort was
not attractive; but future and certain prosperity was before
their eyes, and that not far distant.

The next day we passed through large tracts of country in
flames, volumes of smoke sweeping across the road. Before
noon we joined our former road, and ascended Mount Vic-
toria. I slept at the Weatherboard, and before dark took
another walk to the amphitheatre. On the road to Sydney
I spent a very pleasant evening with Captain King at Dun-

468 CHARLES DARWIN

heved; and thus ended my little excursion in the colony of
New South Wales.

Before arriving here the three things which interested me
most were — the state of society amongst the higher classes,
the condition of the convicts, and the degree of attraction
sufficient to induce persons to emigrate. Of course, after
so very short a visit, one's opinion is worth scarcely any-
thing; but it is as difficult not to form some opinion, as it is
to form a correct judgment. On the whole, from what I
heard, more than from what I saw, I was disappointed in the
state of society. The whole community is rancorously
divided into parties on almost every subject. Among those
who, from their station in life, ought to be the best, many
live in such open profligacy that respectable people cannot
associate with them. There is much jealousy between the
children of the rich emancipist and the free settlers, the
former being pleased to consider honest men as interlopers.
The whole population, poor and rich, are bent on acquiring
wealth: amongst the higher orders, wool and sheep-grazing
form the constant subject of conversation. There are many
serious drawbacks to the comforts of a family, the chief of
which, perhaps, is being surrounded by convict servants.
How thoroughly odious to every feeling, to be waited on by
a man who the day before, perhaps, was flogged, from your
representation, for some trifling misdemeanor. The female
servants are of course, much worse: hence children learn the
vile;>t expressions, and it is fortunate, if not equally vile
ideas.

On the other hand, the capital of a person, without any
trouble on his part, produces him treble interest to what it
will in England ; and with care he is sure to grow rich. The
luxuries of life are in abundance, and very little dearer than
in England, and most articles of food are cheaper. The
climate is splendid, and perfectly healthy; but to my mind
its charms are lost by the uninviting aspect of the country.
Settlers possess a great advantage in finding their sons of
service when very young. At the age of from sixteen to
twenty, they frequently take charge of distant farming sta-
tions. This, however, must happen at the expense of their
boys associating entirely with convict servants. I am not

THE VOYAGE OF THE BEAGLE 469

aware that the tone of society has assumed any peculiar
character; but with such habits, and without intellectual
pursuits, it can hardly fail to deteriorate. My opinion is
such, that nothing but rather sharp necessity should compel
me to emigrate.

The rapid prosperity and future prospects of this colony
are to me, not understanding these subjects, very puzzling.
The two main exports are wool and whale-oil, and to both
of these productions there is a limit. The country is totally
unfit for canals, therefore there is a not very distant point,
beyond which the land-carriage of wool will not repay the
expense of shearing and tending sheep. Pasture everywhere
is so thin that settlers have already pushed far into the
interior: moreover, the country further inland becomes ex-
tremely poor. Agriculture, on account of the droughts, can
never succeed on an extended scale: therefore, so far as I
can see, Australia must ultimately depend upon being the
centre of commerce for the southern hemisphere, and per-
haps on her future manufactories. Possessing coal, she
always has the moving power at hand. From the habitable
country extending along the coast, and from her English
extraction, she is sure to be a maritime nation. I formerly
imagined that Australia would rise to be as grand and power-
ful a country as North America, but now it appears to me
that such future grandeur is rather problematical.

With respect to the state of the convicts, I had still fewer
opportunities of judging than on other points. The first
question is, whether their condition is at all one of punish-
ment: no one will maintain that it is a very severe one.
This, however, I suppose, is of little consequence as long as
it continues to be an object of dread to criminals at home.
The corporeal wants of the convicts are tolerably well sup-
plied: their prospect of future liberty and comfort is not
distant, and, after good conduct, certain. A " ticket of
leave," which, as long as a man keeps clear of suspicion as
well as of crime, makes him free within a certain district, is
given upon good conduct, after years proportional to the
length of the sentence; yet with all this, and overlooking
the previous imprisonment and wretched passage out, I
believe the years of assignment are passed away with discon-

470 CHARLES DARWIN

tent and unhappiness. As an intelligent man remarked to
me, the convicts know no pleasure beyond sensuality, and in
this they are not gratified. The enormous bribe which Gov-
ernment possesses in offering free pardons, together with the
deep horror of the secluded penal settlements, destroys con-
fidence between the convicts, and so prevents crime. As to a
sense of shame, such a feeling does not appear to be known,
and of this I witnessed some very singular proofs. Though
it is a curious fact, I was universally told that the character
of the convict population is one of arrant cowardice : not
unfrequently some become desperate, and quite indifferent as
to life, yet a plan requiring cool or continued courage is
seldom put into execution. The worst feature in the whole
case is, that although there exists what may be called a legal
reform, and comparatively little is committed which the law
can touch, yet that any moral reform should take place
appears to be quite out of the question. I was assured by
well-informed people, that a man who should try to improve,
could not while living with other assigned servants; — his
life would be one of intolerable misery and persecution. Nor
must the contamination of the convict-ships and prisons, both
here and in England, be forgotten. On the whole, as a place
of punishment, the object is scarcely gained; as a real system
of reform it has failed, as perhaps would every other plan;
but as a means of making men outwardly honest, — of con-
verting vagabonds, most useless in one hemisphere, into
active citizens of another, and thus giving birth to a new
and splendid country — a grand centre of civilization — it has
succeeded to a degree perhaps unparalleled in history.

30th. — The Beagle sailed for Hobart Town in Van Die-
men's Land. On the 5th of February, after a six days' pas-
sage, of which the first part was fine, and the latter very cold
and squally, we entered the mouth of Storm Bay: the weather
justified this awful name. The bay should rather be called
an estuary, for it receives at its head the waters of the Der-
went. Near the mouth, there are some extensive basaltic
platforms; but higher up the land becomes mountainous, and
is covered by a light wood. The lower parts of the hills
which skirt the bay are cleared; and the bright yellow fields

THE VOYAGE OF THE BEAGLE 471

of corn, and dark green ones of potatoes, appear very lux-
uriant. Late in the evening we anchored in the snug cove,
on the shores of which stands the capital of Tasmania. The
first aspect of the place was very inferior to that of Sydney ;
the latter might be called a city, this is only a town. It
stands at the base of Mount Wellington, a mountain 3100
feet high, but of little picturesque beauty; from this source,
however, it receives a good supply of water. Round the cove
there are some fine warehouses, and on one side a small fort.
Coming from the Spanish settlements, where such magnifi-
cent care has generally been paid to the fortifications, the
means of defence in these colonies appeared very contempti-
ble. Comparing the town with Sydney, I was chiefly struck
with the comparative fewness of the large houses, either
built or building. Hobart Town, from the census of 1835,
contained 13,826 inhabitants, and the whole of Tasmania

36.505-

All the aborigines have been removed to an island in
Bass's Straits, so that Van Diemen's Land enjoys the great
advantage of being free from a native population. This
most cruel step seems to have been quite unavoidable, as
the only means of stopping a fearful succession of robberies,
burnings, and murders, committed by the blacks; and which
sooner or later would have ended in their utter destruction.
I fear there is no doubt, that this train of evil and its conse-
quences, originated in the infamous conduct of some of
our countrymen. Thirty years is a short period, in which to
have banished the last aboriginal from his native island, —
and that island nearly as large as Ireland. The correspond-
ence on this subject, which took place between the government
at home and that of Van Diemen's Land, is very interesting.
Although numbers of natives were shot and taken prisoners
in the skirmishing, which was going on at intervals for sev-
eral years ; nothing seems fully to have impressed them with
the idea of our overwhelming power, until the whole island,
in 1830, was put under martial law, and by proclamation the
whole population commanded to assist in one great attempt
to secure the entire race. The plan adopted was nearly simi-
lar to that of the great hunting-matches in India : a line was
formed reaching across the island, with the intention of

472 CHARLES DARWIN

driving the natives into a cul-de-sac on Tasman's peninsula.
The attempt failed; the natives, having tied up their dogs,
stole during one night through the lines. This is far from
surprising, when their practised senses, and usual manner
of crawling after wild animals is considered. I have been
assured that they can conceal themselves on almost bare
ground, in a manner which until witnessed is scarcely credi-
ble; their dusky bodies being easily mistaken for the black-
ened stumps which are scattered all over the country. I was
told of a trial between a party of Englishmen and a native,
who was to stand in full view on the side of a bare hill ; if the
Englishmen closed their eyes for less than a minute, he
would squat down, and then they were never able to distin-
guish him from the surrounding stumps. But to return to
the hunting-match; the natives understanding this kind of
warfare, were terribly alarmed, for they at once perceived
the power and numbers of the whites. Shortly afterwards
a party of thirteen belonging to two tribes came in; and,
conscious of their unprotected condition, delivered them-
selves up in despair. Subsequently by the intrepid exertions
of Mr. Robinson, an active and benevolent man, who
fearlessly visited by himself the most hostile of the natives,
the whole were induced to act in a similar manner. They
were then removed to an island, where food and clothes
were provided them. Count Strzelecki states,8 that " at the
epoch of their deportation in 1835, the number of natives
amounted to 210. In 1842, that is, after the interval of seven
years, they mustered only fifty- four individuals; and, while
each family of the interior of New South Wales, uncontami-
nated by contact with the whites, swarms with children, those
of Flinders' Island had during eight years an accession of
only fourteen in number ! "

The Beagle stayed here ten days, and in this time I made
several pleasant little excursions, chiefly with the object of
examining the geological structure of the immediate neigh-
bourhood. The main points of interest consist, first in some
highly fossiliferous strata, belonging to the Devonian or
Carboniferous period; secondly, in proofs of a late small rise
of the land ; and lastly, in a solitary and superficial patch of

• Physical Description of New South Wales and Van Diemen's Land, p-354-

THE VOYAGE OF THE BEAGLE 473

yellowish limestone or travertin, which contains numerous
impressions of leaves of trees, together with land-shells, not
now existing. It is not improbable that this one small quarry
includes the only remaining record of the vegetation of Van
Diemen's Land during one former epoch.

The climate here is damper than in New South Wales,
and hence the land is more fertile. Agriculture flourishes:
the cultivated fields look well, and the gardens abound with
thriving vegetables and fruit-trees. Some of the farm-
houses, situated in retired spots, had a very attractive ap-
pearance. The general aspect of the vegetation is similar to
that of Australia ; perhaps it is a little more green and cheer-
ful; and the pasture between the trees rather more abun-
dant. One day I took a long walk on the side of the bay op-
posite to the town : I crossed in a steamboat, two of which
are constantly plying backwards and forwards. The ma-
chinery of one of these vessels was entirely manufactured in
this colony, which, from its very foundation, then numbered
only three and thirty years ! Another day I ascended Mount
Wellington; I took with me a guide, for I failed in a first
attempt, from the thickness of the wood. Our guide, how-
ever, was a stupid fellow, and conducted us to the southern
and damp side of the mountain, where the vegetation was
very luxuriant ; and where the labour of the ascent, from the
number of rotten trunks, was almost as great as on a moun-
tain in Tierra del Fuego or in Chiloe. It cost us five and a
half hours of hard climbing before we reached the summit.
In many parts the Eucalypti grew to a great size, and com-
posed a noble forest. In some of the dampest ravines, tree-
ferns flourished in an extraordinary manner; I saw one
which must have been at least twenty feet high to the base
of the fronds, and was in girth exactly six feet. The fronds
forming the most elegant parasols, produced a gloomy shade,
like that of the first hour of the night. The summit of the
mountain is broad and flat, and is composed of huge angular
masses of naked greenstone. Its elevation is 3100 feet above
the level of the sea. The day was splendidly clear, and we
enjoyed a most extensive view ; to the north, the country ap-
peared a mass of wooded mountains, of about the same height
with that on which we were standing, and with an equally

474 CHARLES DARWIN

tame outline: to the south the broken land and water, form-
ing many intricate bays, was mapped with clearness before
us. After staying some hours on the summit, we found a
better way to descend, but did not reach the Beagle till eight
o'clock, after a severe day's work.

February ?th. — The Beagle sailed from Tasmania, and,
on the 6th of the ensuing month, reached King George's
Sound, situated close to the S. W. corner of Australia. We
stayed there eight days; and we did not during our voyage
pass a more dull and uninteresting time. The country,
viewed from an eminence, appears a woody plain, with here
and there rounded and partly bare hills of granite protrud-
ing. One day I went out with a party, in hopes of seeing a
kangaroo hunt, and walked over a good many miles of coun-
try. Everywhere we found the soil sandy, and very poor ;
it supported either a coarse vegetation of thin, low brush-
wood and wiry grass, or a forest of stunted trees. The
scenery resembled that of the high sandstone platform of the
Blue Mountains; the Casuarina (a tree somewhat resem-
bling a Scotch fir) is, however, here in greater number, and
the Eucalyptus in rather less. In the open parts there were
many grass-trees, — a plant which, in appearance, has some
affinity with the palm ; but, instead of being surmounted by
a crown of noble fronds, it can boast merely of a tuft of
very coarse grass-like leaves. The general bright green col-
our of the brushwood and other plants, viewed from a dis-
tance, seemed to promise fertility. A single walk, however,
was enough to dispel such an illusion; and he who thinks
with me will never wish to walk again in so uninviting a
country.

One day I accompanied Captain Fitz Roy to Bald Head ;
the place mentioned by so many navigators, where some im-
agined that they saw corals, and others that they saw petri-
fied trees, standing in the position in which they had grown.
According to our view, the beds have been formed by the
wind having heaped up fine sand, composed of minute round-
ed particles of shells and corals, during which process
branches and roots of trees, together with many land-shells,
became enclosed. The whole then became consolidated by
the percolation of calcareous matter; and the cylindrical

THE VOYAGE OF THE BEAGLE 475

cavities left by the decaying of the wood, were thus also
filled up with a hard pseudo-stalactical stone. The weather
is now wearing away the softer parts, and in consequence
the hard casts of the roots and branches of the trees project
above the surface, and, in a singularly deceptive manner, re-
semble the stumps of a dead thicket.

A large tribe of natives, called the White Cockatoo men,
happened to pay the settlement a visit while we were there.
These men, as well as those of the tribe belonging to King
George's Sound, being tempted by the offer of some tubs of
rice and sugar, were persuaded to hold a " corrobery," or
great dancing-party. As soon as it grew dark, small fires
were lighted, and the men commenced their toilet, which
consisted in painting themselves white in spots and lines.
As soon as all was ready, large fires were kept blazing,
round which the women and children were collected as spec-
tators ; the Cockatoo and King George's men formed two dis-
tinct parties, and generally danced in answer to each other.
The dancing consisted in their running either sideways or in
Indian file into an open space, and stamping the ground with
great force as they marched together. Their heavy foot-
steps were accompanied by a kind of grunt, by beating their
clubs and spears together, and by various other gesticula-
tions, such as extending their arms and wriggling their
bodies. It was a most rude, barbarous scene, and, to our
ideas, without any sort of meaning; but we observed that
the black women and children watched it with the greatest
pleasure. Perhaps these dances originally represented actions,
such as wars and victories; there was one called the Emu
dance, in which each man extended his arm in a bent man-
ner, like the neck of that bird. In another dance, one man
imitated the movements of a kangaroo grazing in the woods,
whilst a second crawled up, and pretended to spear him.
When both tribes mingled in the dance, the ground trembled
with the heaviness of their steps, and the air resounded with
their wild cries. Every one appeared in high spirits, and the
group of nearly naked figures, viewed by the light of the
blazing fires, all moving in hideous harmony, formed a per-
fect display of a festival amongst the lowest barbarians. In
Tierra del Fuego, we have beheld many curious scenes in

476 CHARLES DARWIN

savage life, but never, I think, one where the natives were
in such high spirits, and so perfectly at their ease. After
the dancing was over, the whole party formed a great circle
on the ground, and the boiled rice and sugar was distributed,
to the delight of all.

After several tedious delays from clouded weather, on the
1 4th of March, we gladly stood out of King George's Sound
on our course to Keeling Island. Farewell, Australia! you
are a rising child, and doubtless some day will reign a great
princess in the South: but you are too great and ambitious
for affection, yet not great enough for respect. I leave your
shores without sorrow or regret.

APRIL ist. — We arrived in view of the Keeling or
/-\ Cocos Islands, situated in the Indian Ocean, and
about six hundred miles distant from the coast of
Sumatra. This is one of the lagoon-islands (or atolls) of
coral formation, similar to those in the Low Archipelago
which we passed near. When the ship was in the channel
at the entrance, Mr. Liesk, an English resident, came off in
his boat. The history of the inhabitants of this place, in
as few words as possible, is as follows. About nine years
ago, Mr. Hare, a worthless character, brought from the East
Indian archipelago a number of Malay slaves, which now,
including children, amount to more than a hundred. Shortly
afterwards, Captain Ross, who had before visited these isl-
ands in his merchant-ship, arrived from England, bringing
with him his family and goods for settlement: along with
him came Mr. Liesk, who had been a mate in his vessel.
The Malay slaves soon ran away from the islet on which
Mr. Hare was settled, and joined Captain Ross's party. Mr.
Hare upon this was ultimately obliged to leave the place.

The Malays are now nominally in a state of freedom, and
certainly are so, as far as regards their personal treatment;

477

478 CHARLES DARWIN

but in most other points they are considered as slaves. From
their discontented state, from the repeated removals from
islet to islet, and perhaps also from a little mismanagement,
things are not very prosperous. The island has no domestic
quadruped, excepting the pig, and the main vegetable pro-
duction is the cocoa-nut. The whole prosperity of the place
depends on this tree : the only exports being oil from the nut,
and the nuts themselves, which are taken to Singapore and
Mauritius, where they are chiefly used, when grated, in mak-
ing curries. On the cocoa-nut, also, the pigs, which are
loaded with fat, almost entirely subsist, as do the ducks and
poultry. Even a huge land-crab is furnished by nature with
the means to open and feed on this most useful production.

The ring-formed reef of the lagoon-island is surmounted
in the greater part of its length by linear islets. On the
northern or leeward side, there is an opening through which
vessels can pass to the anchorage within. On entering, the
scene was very curious and rather pretty; its beauty, how-
ever, entirely depended on the brilliancy of the surrounding
colours. The shallow, clear, and still water of the lagoon,
resting in its greater part on white sand, is, when illumined
by a vertical sun, of the most vivid green. This brilliant
expanse, several miles in width, is on all sides divided, either
by a line of snow-white breakers from the dark heaving
waters of the ocean, or from the blue vault of heaven by
the strips of land, crowned by the level tops of the cocoa-
nut trees. As a white cloud here and there affords a pleas-
ing contrast with the azure sky, so in the lagoon, bands of
living coral darken the emerald green water.

The next morning after anchoring, I went on shore on
Direction Island. The strip of dry land is only a few hun-
dred yards in width ; on the lagoon side there is a white cal-
careous beach, the radiation from which under this sultry
climate was very oppressive ; and on the outer coast, a solid
broad flat of coral-rock served to break the violence of the
open sea. Excepting near the lagoon, where there is some
sand, the land is entirely composed of rounded fragments of
coral. In such a loose, dry, stony soil, the climate of the
intertropical regions alone could produce a vigorous vegeta-
tion. On some of the smaller islets, nothing could be more

elegant than the manner in which the young and full-grown
cocoa-nut trees, without destroying each other's symmetry,
were mingled into one wood. A beach of glittering white
sand formed a border to these fairy spots.

I will now give a sketch of the natural history of these
islands, which, from its very paucity, possesses a peculiar
interest. The cocoa-nut tree, at the first glance, seems to
compose the whole wood; there are, however, five or six
other trees. One of these grows to a very large size, but
from the extreme softness of its wood, is useless; another
sort affords excellent timber for ship-building. Besides the
trees, the number of plants is exceedingly limited, and con-
sists of insignificant weeds. In my collection, which in-
cludes, I believe, nearly the perfect Flora, there are twenty
species, without reckoning a moss, lichen, and fungus. To
this number two trees must be added ; one of which was not
in flower, and the other I only heard of. The latter is a
solitary tree of its kind, and grows near the beach, where,
without doubt, the one seed was thrown up by the waves. A
Guilandina also grows on only one of the islets. I do not
include in the above list the sugar-cane, banana, some other
vegetables, fruit-trees, and imported grasses. As the islands
consist entirely of coral, and at one time must have existed
as mere water-washed reefs, all their terrestrial productions
must have been transported here by the waves of the sea.
In accordance with this, the Florula has quite the character
of a refuge for the destitute: Professor Henslow informs
me that of the twenty species nineteen belong to different
genera, and these again to no less than sixteen families S1

In Holman's* Travels an account is given, on the author-
ity of Mr. A. S. Keating, who resided twelve months on these
islands, of the various seeds and other bodies which have
been known to have been washed on shore. " Seeds and
plants from Sumatra and Java have been driven up by the
surf on the windward side of the islands. Among them have
been found the Kimiri, native of Sumatra and the peninsula
of Malacca; the cocoa-nut of Balci, known by its shape and
size; the Dadass, which is planted by the Malays with the

pepper-vine, the latter intwining round its trunk, and sup-
porting itself by the prickles on its stem; the soap-tree; the
castor-oil plant ; trunks of the sago palm ; and various kinds
of seeds unknown to the Malays settled on the islands.
These are all supposed to have been driven by the N. W.
monsoon to the coast of New Holland, and thence to these
islands by the S. E. trade-wind. Large masses of Java teak
ind Yellow wood have also been found, besides immense
:rees of red and white cedar, and the blue gumwood of New
Holland, in a perfectly sound condition. All the hardy seeds,
such as creepers, retain their germinating power, but the
softer kinds, among which is the mangostin, are destroyed
in the passage. Fishing-canoes, apparently from Java, have
at times been washed on shore." It is interesting thus to
discover how numerous the seeds are, which, coming from
several countries, are drifted over the wide ocean. Pro-
fessor Henslow tells me, he believes that nearly all the plants
which I brought from these islands, are common littoral
species in the East Indian archipelago. From the direction,
however, of the winds and currents, it seems scarcely pos-
sible that they could have come here in a direct line. If,
as suggested with much probability by Mr. Keating, they
were first carried towards the coast of New Holland, and
thence drifted back together with the productions of that
country, the seeds, before germinating, must have travelled
between 1800 and 2400 miles.

Chamisso,* when describing the Radack Archipelago, situ-
ated in the western part of the Pacific, states that " the sea
brings to these islands the seeds and fruits of many trees,
most of which have yet not grown here. The greater part
of these seeds appear to have not yet lost the capability of
growing."

It is also said that palms and bamboos from some-
where in the torrid zone, and trunks of northern firs, are
washed on shore: these firs must have come from an im-
mense distance. These facts are highly interesting. It can-
not be doubted that if there were land-birds to pick up the
seeds when first cast on shore, and a soil better adapted for
their growth than the loose blocks of coral, that the most

isolated of the lagoon-islands would in time possess a far
more abundant Flora than they now have.

The list of land animals is even poorer than that of the
plants. Some of the islets are inhabited by rats, which were
brought in a ship from the Mauritius, wrecked here. These
rats are considered by Mr. Waterhouse as identical with the
English kind, but they are smaller, and more brightly col-
oured. There are no true land-birds ; for a snipe and a rail
(Rallus Phillippensis), though living entirely in the dry
herbage, belong to the order of Waders. Birds of this order
are said to occur on several of the small low islands in the
Pacific. At Ascension, where there is no land-bird, a rail
(Porphyrio simplex) was shot near the summit of the moun-
tain, and it was evidently a solitary straggler. At Tristan
d'Acunha, where, according to Carmichael, there are only
two land-birds, there is a coot. From these facts I believe
that the waders, after the innumerable web-footed species,
are generally the first colonists of small isolated islands. I
may add, that whenever I noticed birds, not of oceanic
species, very far out at sea, they always belonged to this
order; and hence they would naturally become the earliest
colonists of any remote point of land.

Of reptiles I saw only one small lizard. Of insects I took
pains to collect every kind. Exclusive of spiders, which were
numerous, there were thirteen species.* Of these, one only
was a beetle. A small ant swarmed by thousands under the
loose dry blocks of coral, and was the only true insect which
was abundant. Although the productions of the land are
thus scanty, if we look to the waters of the surrounding sea,
the number of organic beings is indeed infinite. Chamisso
has described5 the natural history of a lagoon-island in the
Radack Archipelago; and it is remarkable how closely its
inhabitants, in number and kind, resemble those of Keeling
Island. There is one lizard and two waders, namely, a snipe
and curlew. Of plants there are nineteen species, including
a fern ; and some of these are the same with those growing

*The thirteen species belong to the following orders: — In the Coleop-
tera, a minute Elater ; Orthoptera, a Gryllus ana a Blatta ; Hemiptera, one
species; Homoptera, two; Nevroptera, a Chrysopa; Hymenoptera, two ants;
Lepidoptera nocturna, a Diopsea, and a Pteropiiorttt ( ?) ; Diptera, two species.

here, though on a spot so immensely remote, and in a dif-
ferent ocean.

The long strips of land, forming the linear islets, have
been raised only to that height to which the surf can throw
fragments of coral, and the wind heap up calcareous sand.
The solid flat of coral rock on the outside, by its breadth,
breaks the first violence of the waves, which otherwise, in a
day, would sweep away these islets and all their productions.
The ocean and the land seem here struggling for mastery :
although terra firma has obtained a footing, the denizens of
the water think their claim at least equally good. In every
part one meets hermit crabs of more than one species,* car-
rying on their backs the shells which they have stolen from
the neighbouring beach. Overhead, numerous gannets, frig-
ate-birds, and terns, rest on the trees; and the wood, from
the many nests and from the smell of the atmosphere, might
be called a sea-rookery. The gannets, sitting on their rude
nests, gaze at one with a stupid yet angry air. The noddies,
as their name expresses, are silly little creatures. But there
is one charming bird : it is a small, snow-white tern, which
smoothly hovers at the distance of a few feet above one's
head, its large black eye scanning, with quiet curiosity, your
expression. Little imagination is required to fancy that so
light and delicate a body must be tenanted by some wander-
ing fairy spirit.

Sunday, April $rd. — After service I accompanied Captain
Fitz Roy to the settlement, situated at the distance of some
miles, on the point of an islet thickly covered with tall cocoa-
nut trees. Captain Ross and Mr. Liesk live in a large barn-
like house open at both ends, and lined with mats made of
woven bark. The houses of the Malays are arranged along
the shore of the lagoon. The whole place had rather a deso-
late aspect, for there were no gardens to show the signs of
care and cultivation. The natives belong to different islands
in the East Indian archipelago, but all speak the same lan-
guage : we saw the inhabitants of Borneo, Celebes, Java, and

Sumatra. In colour they resemble the Tahitians, from whom
they do not widely differ in features. Some of the women,
however, show a good deal of the Chinese character. I liked
both their general expressions and the sound of their voices.
They appeared poor, and their houses were destitute of fur-
niture; but it was evident, from the plumpness of the little
children, that cocoa-nuts and turtle afford no bad sustenance.

On this island the wells are situated, from which ships
obtain water. At first sight it appears not a little remarkable
that the fresh water should regularly ebb and flow with the
tides ; and it has even been imagined, that sand has the power
of filtering the salt from the sea-water. These ebbing wells
are common on some of the low islands in the West Indies.
The compressed sand, or porous coral rock, is permeated like
a sponge with the salt water ; but the rain which falls on the
surface must sink to the level of the surrounding sea, and
must accumulate there, displacing an equal bulk of the salt
water. As the water in the lower part of the great sponge-
like coral mass rises and falls with the tides, • so will the
water near the surface ; and this will keep fresh, if the mass
be sufficiently compact to prevent much mechanical admix-
ture; but where the land consists of great loose blocks of
coral with open interstices, if a well be dug, the water, as I
have seen, is brackish.

After dinner we stayed to see a curious half superstitious
scene acted by the Malay women. A large wooden spoon
dressed in garments, and which had been carried to the grave
of a dead man, they pretend becomes inspired at the full of
the moon, and will dance and jump about. After the proper
preparations, the spoon, held by two women, became con-
vulsed, and danced in good time to the song of the surround-
ing children and women. It was a most foolish spectacle;
but Mr. Liesk maintained that many of the Malays believed
in its spiritual movements. The dance did not commence till
the moon had risen, and it was well worth remaining to be-
hold her bright orb so quietly shining through the long arms
of the cocoa-nut trees as they waved in the evening breeze.
These scenes of the tropics are in themselves so delicious,
that they almost equal those dearer ones at home, to which
we are bound by each best feeling of the mind.

484 CHARLES DARWIN

The next day I employed myself in examining the very in-
teresting, yet simple structure and origin of these islands.
The water being unusually smooth, I waded over the outer
flat of dead rock as far as the living mounds of coral, on
which the swell of the open sea breaks. In some of the
gullies and hollows there were beautiful green and other col-
oured fishes, and the form and tints of many of the zoophytes
were admirable. It is excusable to grow enthusiastic over
the infinite numbers of organic beings with which the sea of
the tropics, so prodigal of life, teems; yet I must confess I
think those naturalists who have described, in well-known
words, the submarine grottoes decked with a thousand beau-
ties, have indulged in rather exuberant language.

April 6th. — I accompanied Captain Fitz Roy to an island
at the head of the lagoon : the channel was exceedingly intri-
cate, winding through fields of delicately branched corals.
We saw several turtle and two boats were then employed in
catching them. The water was so clear and shallow, that al-
though at first a turtle quickly dives out of sight, yet in a
canoe or boat under sail, the pursuers after no very long
chase come up to it. A man standing ready in the bow, at
this moment dashes through the water upon the turtle's back ;
then clinging with both hands by the shell of its neck, he is
carried away till the animal becomes exhausted and is se-
cured. It was quite an interesting chase to see the two boats
thus doubling about, and the men dashing head foremost
into the water trying to seize their prey. Captain Moresby
informs me that in the Chagos archipelago in this same
ocean, the natives, by a horrible process, take the shell from
the back of the living turtle. " It is covered with burning
charcoal, which causes the outer shell to curl upwards; it is
then forced off with a knife, and before it becomes cold
flattened between boards. After this barbarous process the
animal is suffered to regain its native element, where, after
a certain time, a new shell is formed; it is, however, too
thin to be of any service, and the animal always appears
languishing and sickly."

When we arrived at the head of the lagoon, we crossed a
narrow islet, and found a great surf breaking on the wind-
ward coast. I can hardly explain the reason, but there is to

THE VOYAGE OF THE BEAGLE 485

my mind much grandeur in the view of the outer shores of
these lagoon-islands. There is a simplicity in the barrier-
like beach, the margin of green bushes and tall cocoa-nuts,
the solid flat of dead coral-rock, strewed here and there
with great loose fragments, and the line of furious break-
ers, all rounding away towards either hand. The ocean
throwing its waters over the broad reef appears an invinci-
ble, all-powerful enemy; yet we see it resisted, and even
conquered, by means which at first seem most weak and in-
efficient. It is not that the ocean spares the rock of coral;
the great fragments scattered over the reef, and heaped on
the beach, whence the tall cocoa-nut springs, plainly be-
speak the unrelenting power of the waves. Nor are any
periods of repose granted. The long swell caused by the
gentle but steady action of the trade-wind, always blow-
ing in one direction over a wide area, causes breakers, almost
equalling in force those during a gale of wind in the tem-
perate regions, and which never cease to rage. It is impos-
sible to behold these waves without feeling a conviction that
an island, though built of the hardest rock, let it be porphyry,
granite, or quartz, would ultimately yield and be demolished
by such an irresistible power. Yet these low, insignificant
coral-islets stand and are victorious : for here another power,
as an antagonist, takes part in the contest. The organic forces
separate the atoms of carbonate of lime, one by one, from
the foaming breakers, and unite them into a symmetrical
structure. Let the hurricane tear up its thousand huge frag-
ments ; yet what will that tell against the accumulated labour
of myriads of architects at work night and day, month after
month? Thus do we see the soft and gelatinous body of a
polypus, through the agency of the vital laws, conquering
the great mechanical power of the waves of an ocean which
neither the art of man nor the inanimate works of nature
could successfully resist.

We did not return on board till late in the evening, for we
stayed a long time in the lagoon, examining the fields of
coral and the gigantic shells of the chama, into which, if a
man were to put his hand, he would not, as long as the ani-
mal lived, be able to withdraw it. Near the head of the
lagoon I was much surprised to find a wide area, consider-

486 CHARLES DARWIN

ably more than a mile square, covered with a forest of deli-
cately branching corals, which, though standing upright,
were all dead and rotten. At first I was quite at a loss to
understand the cause; afterwards it occurred to me that it
was owing to the following rather curious combination of
circumstances. It should, however, first be stated, that corals
are not able to survive even a short exposure in the air to
the sun's rays, so that their upward limit of growth is de-
termined by that of lowest water at spring tides. It appears,
from some old charts, that the long island to windward was
formerly separated by wide channels into several islets; this
fact is likewise indicated by the trees being younger on these
portions. Under the former condition of the reef, a strong
breeze, by throwing more water over the barrier, would tend
to raise the level of the lagoon. Now it acts in a directly
contrary manner; for the water within the lagoon not only
is not increased by currents from the outside, but is itself
blown outwards by the force of the wind. Hence it is ob-
served, that the tide near the head of the lagoon does not
rise so high during a strong breeze as it does when it is
calm. This difference of level, although no doubt very small,
has, I believe, caused the death of those coral-groves, which
under the former and more open condition of the outer reef
has attained the utmost possible limit of upward growth.

A few miles north of Keeling there is another small atoll,
the lagoon of which is nearly filled up with coral-mud. Cap-
tain Ross found embedded in the conglomerate on the outer
coast, a well-rounded fragment of greenstone, rather larger
than a man's head : he and the men with him were so much
surprised at this, that they brought it away and preserved it
as a curiosity. The occurrence of this one stone, where
every other particle of matter is calcareous, certainly is very
puzzling. The island has scarcely ever been visited, nor is it
probable that a ship had been wrecked there. From the ab-
sence of any better explanation, I came to the conclusion that
it must have come entangled in the roots of some large tree :
when, however, I considered the great distance from the
nearest land, the combination of chances against a stone thus
being entangled, the tree washed into the sea, floated so far,
then landed safely, and the stone finally so embedded as to

THE VOYAGE OP THE BEAGLE 487

allow of its discovery, I was almost afraid of imagining a
means of transport apparently so improbable. It was there-
fore with great interest that I found Chamisso, the justly
distinguished naturalist who accompanied Kotzebue, stating
that the inhabitants of the Radack archipelago, a group of
lagoon-islands in the midst of the Pacific, obtained stones
for sharpening their instruments by searching the roots of
trees which are cast upon the beach. It will be evident that
this must have happened several times, since laws have been
established that such stones belong to the chief, and a pun-
ishment is inflicted on any one who attempts to steal them.
When the isolated position of these small islands in the
midst of a vast ocean — their great distance from any land
excepting that of coral formation, attested by the value
which the inhabitants, who are such bold navigators, attach
to a stone of any kind,7 — and the slowness of the currents of
the open sea, are all considered, the occurrence of pebbles
thus transported does appear wonderful. Stones may often
be thus carried ; and if the island on which they are stranded
is constructed of any other substance besides coral, they
would scarcely attract attention, and their origin at least
would never be guessed. Moreover, this agency may long
escape discovery from the probability of trees, especially
those loaded with stones, floating beneath the surface. In
the channels of Tierra del Fuego large quantities of drift
timber are cast upon the beach, yet it is extremely rare to
meet a tree swimming on the water. These facts may pos-
sibly throw light on single stones, whether angular or
rounded, occasionally found embedded in fine sedimentary
masses.

During another day I visited West Islet, on which the
vegetation was perhaps more luxuriant than on any other.
The cocoa-nut trees generally grow separate, but here the
young ones flourished beneath their tall parents, and formed
with their long and curved fronds the most shady arbours.
Those alone who have tried it, know how delicious it is to
be seated in such shade, and drink the cool pleasant fluid
of the cocoa-nut. In this island there is a large bay-like

space, composed of the finest white sand: it is quite level
and is only covered by the tide at high water; from this
large bay smaller creeks penetrate the surrounding woods.
To see a field of glittering white sand, representing water,
with the cocoa-nut trees extending their tall and waving
trunks around the margin, formed a singular and very pretty
view.

I have before alluded to a crab which lives on the cocoa-
nuts; it is very common on all parts of the dry land, and
grows to a monstrous size: it is closely allied or identical
with the Birgos latro. The front pair of legs terminate in
very strong and heavy pincers, and the last pair are fitted
with others weaker and much narrower. It would at first
be thought quite impossible for a crab to open a strong
cocoa-nut covered with the husk; but Mr. Liesk assures me
that he has repeatedly seen this effected. The crab begins
by tearing the husk, fibre by fibre, and always from that
end under which the three eye-holes are situated; when this
is completed, the crab commences hammering with its heavy
claws on one of the eye-holes till an opening is made. Then
turning round its body, by the aid of its posterior and nar-
row pair of pincers, it extracts the white albuminous sub-
stance. I think this is as curious a case of instinct as ever
I heard of, and likewise of adaptation in structure between
two objects apparently so remote from each other in the
scheme of nature, as a crab and a cocoa-nut tree. The
Birgos is diurnal in its habits ; but every night it is said to
pay a visit to the sea, no doubt for the purpose of moistening
its branchiae. The young are likewise hatched, and live for
some time, on the coast. These crabs inhabit deep burrows,
which they hollow out beneath the roots of trees ; and where
they accumulate surprising quantities of the picked fibres
of the cocoa-nut husk, on which they rest as on a bed. The
Malays sometimes take advantage of this, and collect the
fibrous mass to use as junk. These crabs are very good to
eat; moreover, under the tail of the larger ones there is a
mass of fat, which, when melted, sometimes yields as much
as a quart bottle full of limpid oil. It has been stated by
some authors that the Birgos crawls up the cocoa-nut trees
for the purpose of stealing the nuts: I very much doubt the

THE VOYAGE OF THE BEAGLE 489

possibility of this; but with the Pandanus8 the task would be
very much easier. I was told by Mr. Liesk that on these
islands the Birgos lives only on the nuts which have fallen
to the ground.

Captain Moresby informs me that this crab inhabits the
Chagos and Seychelle groups, but not the neighbouring Mai-
diva archipelago. It formerly abounded at Mauritius, but
only a few small ones are now found there. In the Pacific,
this species, or one with closely allied habits, is said' to in-
habit a single coral island, north of the Society group. To
show the wonderful strength of the front pair of pincers, I
may mention, that Captain Moresby confined one in a strong
tin-box, which had held biscuits, the lid being secured with
wire; but the crab turned down the edges and escaped. In
turning down the edges, it actually punched many small
holes quite through the tin !

I was a good deal surprised by finding two species of
coral of the genus Millepora (M. complanata and alcicornis),
possessed of the power of stinging. The stony branches or
plates, when taken fresh from the water, have a harsh feel
and are not slimy, although possessing a strong and dis-
agreeable smell. The stinging property seems to vary in
different specimens : when a piece was pressed or rubbed on
the tender skin of the face or arm, a pricking sensation was
usually caused, which came on after the interval of a second,
and lasted only for a few minutes. One day, however, by
merely touching my face with one of the branches, pain was
instantaneously caused; it increased as usual after a few
seconds, and remaining sharp for some minutes, was percep-
tible for half an hour afterwards. The sensation was as
bad as that from a nettle, but more like that caused by the
Physalia or Portuguese man-of-war. Little red spots were
produced on the tender skin of the arm, which appeared as if
they would have formed watery pustules, but did not. M.
Quoy mentions this case of the Millepora ; and I have heard
of stinging corals in the West Indies. Many marine ani-
mals seem to have this power of stinging : besides the Portu-
guese man-of-war, many jelly-fish, and the Aplysia or sea-

slug of the Cape de Verd Islands, it is stated in the voyage
of the Astrolabe, that an Actinia or sea-anemone, as well as
a flexible coralline allied to Sertularia, both possess this
means of offence or defence. In the East Indian sea, a
stinging sea-weed is said to be found.

Two species of fish, of the genus Scarus, which are com-
mon here, exclusively feed on coral : both are coloured of a
splendid bluish-green, one living invariably in the lagoon,
and the other amongst the outer breakers. Mr. Liesk assured
us, that he had repeatedly seen whole shoals grazing with
their strong bony jaws on the tops of the coral branches: I
opened the intestines of several, and found them distended
with yellowish calcareous sandy mud. The slimy disgusting
Holuthuriae (allied to our star-fish), which the Chinese gour-
mands are so fond of, also feed largely, as I am informed by
Dr. Allan, on corals; and the bony apparatus within their
bodies seems well adapted for this end. These Holuthuriae,
the fish, the numerous burrowing shells, and nereidous
worms, which perforate every block of dead coral, must be
very efficient agents in producing the fine white mud which
lies at the bottom and on the shores of the lagoon. A por-
tion, however, of this mud, which when wet resembled
pounded chalk, was found by Professor Ehrenberg to be
partly composed of siliceous-shielded infusoria.

April izth. — In the morning we stood out of the lagoon
on our passage to the Isle of France. I am glad we have
visited these islands : such formations surely rank high
amongst the wonderful objects of this world. Captain Fitz
Roy found no bottom with a line 7200 feet in length, at the
distance of only 2200 yards from the shore ; hence this island
forms a lofty submarine mountain, with sides steeper even
than those of the most abrupt volcanic cone. The saucer-
shaped summit is nearly ten miles across; and every single
atom,10 from the least particle to the largest fragment of
rock, in this great pile, which however is small compared
with very many other lagoon-islands, bears the stamp of
having been subjected to organic arrangement. We feel sur-

10 I exclude, of course, some soil which has been imported here in ves-
sels from Malacca and Java, and likewise some small fragments of pumice,
drifted here by the waves. The one block of greenstone, moreover, on the
northern island must be excepted.

prise when travellers tell us of the vast dimensions of the
Pyramids and other great ruins, but how utterly insignificant
are the greatest of these, when compared to these moun-
tains of stone accumulated by the agency of various minute
and tender animals ! This is a wonder which does not at
first strike the eye of the body, but, after reflection, the eye
of reason.

I will now give a very brief account of the three great
classes of coral-reefs; namely, Atolls, Barrier, and Fringing-
reefs, and will explain my views" on their formation. Al-
most every voyager who has crossed the Pacific has ex-
pressed his unbounded astonishment at the lagoon-islands, or
as I shall for the future call them by their Indian name of
atolls, and has attempted some explanation. Even as long
ago as the year 1605, Pyrard de Laval well exclaimed, " C'est

une merveille de voir chacun de ces atollons, environne d'un
grand bane de pierre tout autour, n'y ayant point d'artifice
humain." The accompanying sketch of Whitsunday Island
in the Pacific, copied from Capt. Beechey's admirable Voy-
age, gives but a faint idea of the singular aspect of an atoll:
it is one of the smallest size, and has its narrow islets united
together in a ring. The immensity of the ocean, the fury of
the breakers, contrasted with the lowness of the land and the
smoothness of the bright green water within the lagoon, can
hardly be imagined without having been seen.

The earlier voyagers fancied that the coral-building ani-

11 These were first read before the Geological Society in May, 1837, and
have since been developed in a separate volume on the " Structure and
Distribution of Coral Reefs."

492 CHARLES DARWIN

mals instinctively built up their great circles to afford them-
selves protection in the inner parts; but so far is this from
the truth, that those massive kinds, to whose growth on the
exposed outer shores the very existence of the reef depends,
cannot live within the lagoon, where other delicately-branch-
ing kinds flourish. Moreover, on this view, many species
of distinct genera and families are supposed to combine for
one end ; and of such a combination, not a single instance
can be found in the whole of nature. The theory that has
been most generally received is, that atolls are based on sub-
marine craters; but when we consider the form and size of
some, the number, proximity, and relative positions of others,
this idea loses its plausible character : thus Suadiva atoll is 44
geographical miles in diameter in one line, by 34 miles in an-
other line; Rimsky is 54 by 20 miles across, and it has a
strangely sinuous margin ; Bow atoll is 30 miles long, and on
an average only 6 in width ; Menchicoff atoll consists of three
atolls united or tied together. This theory, moreover, is to-
tally inapplicable to the northern Maldiva atolls in the Indian
Ocean (one of which is 88 miles in length, and between 10
and 20 in breadth), for they are not bounded like ordinary
atolls by narrow reefs, but by a vast number of separate
little atolls; other little atolls rising out of the great central
lagoon-like spaces. A third and better theory was advanced
by Chamisso, who thought that from the corals growing more
vigorously where exposed to the open sea, as undoubtedly is
the case, the outer edges would grow up from the general
foundation before any other part, and that this would ac-
count for the ring or cup-shaped structure. But we shall
immediately see, that in this, as well as in the crater-theory,
a most important consideration has been overlooked, namely,
on what have the reef-building corals, which cannot live at
a great depth, based their massive structures?

Numerous soundings were carefully taken by Captain Fitz
Roy on the steep outside of Keeling atoll, and it was found
that within ten fathoms, the prepared tallow at the bottom
of the lead, invariably came up marked with the impression
of living corals, but as perfectly clean as if it had been
dropped on a carpet of turf ; as the depth increased, the im-
pressions became less numerous, but the adhering particles

THE VOYAGE OF THE BEAGLE 493

of sand more and more numerous, until at last it was evident
that the bottom consisted of a smooth sandy layer : to carry
on the analogy of the turf, the blades of grass grew thinner
and thinner, till at last the soil was so sterile, that nothing
sprang from it. From these observations, confirmed by many
others, it may be safely inferred that the utmost depth at
which corals can construct reefs is between 20 and 30 fath-
oms. Now there are enormous areas in the Pacific and Indian
Ocean, in which every single island is of coral formation,
and is raised only to that height to which the waves can
throw up fragments, and the winds pile up sand. Thus
Radack group of atolls is an irregular square, 520 miles long
and 240 broad; the Low Archipelago is elliptic-formed, 840
miles in its longer, and 420 in its shorter axis: there are
other small groups and single low islands between these two
archipelagoes, making a linear space of ocean actually more
than 4000 miles in length, in which not one single island
rises above the specified height. Again, in the Indian Ocean
there is a space of ocean 1500 miles in length, including
three archipelagoes, in which every island is low and of
coral formation. From the fact of the reef-building corals
not living at great depths, it is absolutely certain that
throughout these vast areas, wherever there is now an atoll,
a foundation must have originally existed within a depth of
from 20 to 30 fathoms from the surface. It is improbable in
the highest degree that broad, lofty, isolated, steep-sided
banks of sediment, arranged in groups and lines hundreds of
leagues in length, could have been deposited in the central
and profoundest parts of the Pacific and Indian Oceans, at
an immense distance from any continent, and where the
water is perfectly limpid. It is equally improbable that the
elevatory forces should have uplifted throughout the above
vast areas, innumerable great rocky banks within 20 to 30
fathoms, or 120 to 180 feet, of the surface of the sea, and
not one single point above that level ; for where on the whole
surface of the globe can we find a single chain of mountains,
even a few hundred miles in length, with their many sum-
mits rising within a few feet of a given level, and not one
pinnacle above it? If then the foundations, whence the atoll-
building corals sprang, were not formed of sediment, and if

494 CHARLES DARWIN

they were not lifted up to the required level, they must of
necessity have subsided into it; and this at once solves the
difficulty. For as mountain after mountain, and island after
island, slowly sank beneath the water, fresh bases would be
successively afforded for the growth of the corals. It is
impossible here to enter into all the necessary details, but I
venture to defy12 any one to explain in any other manner
how it is possible that numerous islands should be distributed
throughout vast areas — all the islands being low — all being
built of corals, absolutely requiring a foundation within a
limited depth from the surface.

Before explaining how atoll-formed reefs acquire their
peculiar structure, we must turn to the second great class,
namely, Barrier-reefs. These either extend in straight lines
in front of the shores of a continent or of a large island, or
they encircle smaller islands; in both cases, being separated
from the land by a broad and rather deep channel of water,
analogous to the lagoon within an atoll. It is remarkable
how little attention has been paid to encircling barrier-reefs ;
yet they are truly wonderful structures. The following sketch
represents part of the barrier encircling the island of Bola-
bola in the Pacific, as seen from one of the central peaks.
In this instance the whole line of reef has been converted
into land; but usually a snow-white line of great breakers,
with only here and there a single low islet crowned with
cocoa-nut trees, divides the dark heaving waters of the ocean
from the light-green expanse of the lagoon-channel. And
the quiet waters of this channel generally bathe a fringe of
low alluvial soil, loaded with the most beautiful productions
of the tropics, and lying at the foot of the wild, abrupt, cen-
tral mountains.

Encircling barrier-reefs are of all sizes, from three miles
to no less than forty-four miles in diameter ; and that which
fronts one side, and encircles both ends, of New Caledonia,
is 400 miles long. Each reef includes one, two, or several
rocky islands of various heights; and in one instance, even

13 It is remarkable that Mr. Lyell, even in the first edition of his " Prin-
ciples of Geology," inferred that the amount of subsidence in the Pacific
must have exceeded that of elevation, from the area of land being very
small relatively to the agents there tending to form it, namely, the growth
of coral and volcanic action.

THE VOYAGE OF THE BEAGLE 495

as many as twelve separate islands. The reef runs at a
greater or less distance from the included land; in the
Society archipelago generally from one to three or four
miles; but at Hogoleu the reef is 20 miles on the southern
side, and 14 miles on the opposite or northern side, from the
included islands. The depth within the lagoon-channel also
varies much; from 10 to 30 fathoms may be taken as an
average; but at Vanikoro there are spaces no less than 56
fathoms or 363 feet deep. Internally the reef either slopes
gently into the lagoon-channel, or ends in a perpendicular
wall sometimes between two and three hundred feet under
water in height: externally the reef rises, like an atoll, with
extreme abruptness out of the profound depths of the ocean.
What can be more singular than these structures? We see

an island, which may be compared to a castle situated on the
summit of a lofty submarine mountain, protected by a great
wall of coral-rock, always steep externally and sometimes
internally, with a broad level summit, here and there breached
by a narrow gateway, through which the largest ships can
enter the wide and deep encircling moat.

As far as the actual reef of coral is concerned, there is not
the smallest difference, in general size, outline, grouping,
and even in quite trifling details of structure, between a
barrier and an atoll. The geographer Balbi has well remarked,
that an encircled island is an atoll with high land rising out
of its lagoon; remove the land from within, and a perfect
atoll is left.

But what has caused these reefs to spring up at such

496

CHARLES DARWIN

great distances from the shores of the included islands? It
cannot be that the corals will not grow close to the land;
for the shores within the lagoon-channel, when not sur-
rounded by alluvial soil, are often fringed by living reefs;
and we shall presently see that there is a whole class, which
I have called Fringing Reefs from their close attachment
to the shores both of continents and of islands. Again, on
what have the reef-building corals, which cannot live at
great depths, based their encircling structures? This is a
great apparent difficulty, analogous to that in the case of
atolls, which has generally been overlooked. It will be per-
ceived more clearly by inspecting the following sections,
which are real ones, taken in north and south lines, through
the islands with their barrier-reefs, of Vanikoro, Gambier,
and Maurua; and they are laid down, both vertically and
horizontally, on the same scale of a quarter of an inch to
a mile.

It should be observed that the sections might have been
taken in any direction through these islands, or through

many other encircled islands, and the general features would
have been the same. Now, bearing in mind that reef-build-
ing coral cannot live at a greater depth than from 20 to 30
fathoms, and that the scale is so small that the plummets on
the right hand show a depth of 200 fathoms, on what are

THE VOYAGE OF THE BEAGLE 497

these barrier-reefs based? Are we to suppose that each
island is surrounded by a collar-like submarine ledge of rock,
or by a great bank of sediment, ending abruptly where the
reef ends?

If the sea had formerly eaten deeply into the isl-
ands, before they were protected by the reefs, thus having
left a shallow ledge round them under water, the present
shores would have been invariably bounded by great preci-
pices; but this is most rarely the case. Moreover, on this
notion, it is not possible to explain why the corals should
have sprung up, like a wall, from the extreme outer margin
of the ledge, often leaving a broad space of water within,
too deep for the growth of corals. The accumulation of a
wide bank of sediment all round these islands, and generally
widest where the included islands are smallest, is highly im-
probable, considering their exposed positions in the central
and deepest parts of the ocean. In the case of the barrier-
reef of New Caledonia, which extends for 150 miles beyond
the northern point of the islands, in the same straight line
with which it fronts the west coast, it is hardly possible to
believe that a bank of sediment could thus have been
straightly deposited in front of a lofty island, and so far
beyond its termination in the open sea. Finally, if we look
to other oceanic islands of about the same height and of
similar geological constitution, but not encircled by coral-
reefs, we may in vain search for so trifling a circumambient
depth as 30 fathoms, except quite near to their shores; for
usually land that rises abruptly out of water, as do most of
the encircled and non-encircled oceanic islands, plunges ab-
ruptly under it. On what then, I repeat, are these barrier-
reefs based? Why, with their wide and deep moat-like chan-
nels, do they stand so far from the included land ? We shall
soon see how easily these difficulties disappear.

We come now to our third class of Fringing-reefs, which
will require a very short notice. Where the land slopes ab-
ruptly under water, these reefs are only a few yards in width,
forming a mere ribbon or fringe round the shores: where
the land slopes gently under the water the reef extends
further, sometimes even as much as a mile from the land;
but in such cases the soundings outside the reef always show

498 CHARLES DARWIN

that the submarine prolongation of the land is gently inclined
In fact, the reefs extend only to that distance from the shore,
at which a foundation within the requisite depth from 20 to
30 fathoms is found. As far as the actual reef is concerned,
there is no essential difference between it and that forming
a barrier or an atoll : it is, however, generally of less width,
and consequently few islets have been formed on it. From
the corals growing more vigorously on the outside, and from
the noxious effect of the sediment washed inwards, the outer
edge of the reef is the highest part, and between it and the
land there is generally a shallow sandy channel a few feet in
depth. Where banks or sediments have accumulated near to
the surface, as in parts of the West Indies, they sometimes
become fringed with corals, and hence in some degree resem-
ble lagoon-islands or atolls, in the same manner as fringing-
reefs, surrounding gently sloping islands, in some degree
resemble barrier-reefs.

No theory on the formation of coral-reefs can be con-
sidered satisfactory which does not include the three great

classes. We have seen that we are driven to believe in the
subsidence of those vast areas, interspersed with low islands,
of which not one rises above the height to which the wind and
waves can throw up matter, and yet are constructed by ani-
mals requiring a foundation, and that foundation to lie at
no great depth. Let us then take an island surrounded by
f ringing-reefs, which offer no difficulty in their structure;

THE VOYAGE OF THE BEAGLE 499

and let this island with its reefs, represented by the unbroken
lines in the woodcut, slowly subside. Now, as the island
sinks down, either a few feet at a time or quite insensibly,
we may safely infer, from what is known of the conditions
favourable to the growth of coral, that the living masses,
bathed by the surf on the margin of the reef, will soon regain
the surface. The water, however, will encroach little by little
on the shore, the island becoming lower and smaller, and the
space between the inner edge of the reef and the beach pro-
portionately broader. A section of the reef and island in this
state, after a subsidence of several hundred feet, is given by
the dotted lines. Coral islets are supposed to have been
formed on the reef; and a ship is anchored in the lagoon-
channel. This channel will be more or less deep, according
to the rate of subsidence, to the amount of sediment accumu-
lated in it, and to the growth of the delicately branched corals
which can live there. The section in this state resembles in
every respect one drawn through an encircled island : in fact,
it is a real section (on the scale of .517 of an inch to a mile)
through Bolabola in the Pacific. We can now at once see
why encircling barrier-reefs stand so far from the shores
which they front. We can also perceive, that a line drawn
perpendicularly down from the outer edge of the new reef,
to the foundation of solid rock beneath the old fringing-reef,
will exceed by as many feet as there have been feet of
subsidence, that small limit of depth at which the effective
corals can live: — the little architects having built up their
great wall-like mass, as the whole sank down, upon a basis
formed of other corals and their consolidated fragments.
Thus the difficulty on this head, which appeared so great,
disappears.

If, instead of an island, we had taken the shore of a con-
tinent fringed with reefs, and had imagined it to have sub-
sided, a great straight barrier, like that of Australia or New
Caledonia, separated from the land by a wide and deep chan-
nel, would evidently have been the result.

Let us take our new encircling barrier-reef, of which the
section is now represented by unbroken lines, and which, as
I have said, is a real section through Bolabola, and let it go
on subsiding. As the barrier-reef slowly sinks down, the

500 CHARLES DARWIN

corals will go on vigorously growing upwards; but as the
island sinks, the water will gain inch by inch on the shore—-

one great reef — and finally, the last and highest pinnacle
disappearing. The instant this takes place, a perfect atoll
is formed : I have said, remove the high land from within an
encircling barrier-reef, and an atoll is left, and the land has
been removed. We can now perceive how it comes that
atolls, having sprung from encircling barrier-reefs, resemble
them in general size, form, in the manner in which they are
grouped together, and in their arrangement in single or
double lines; for they may be called rude outline charts of
the sunken islands over which they stand. We can further
see how it arises that the atolls in the Pacific and Indian
Oceans extend in lines parallel to the generally prevailing
strike of the high islands and great coast-lines of those
oceans. I venture, therefore, to affirm, that on the theory of
the upward growth of the corals during the sinking of the
land,18 all the leading features in those wonderful structures,

18 It has been highly satisfactory to me to find the following passage in
a pamplet by Mr. Couthouy, one of the naturalists in the great Antarctic
Expedition of the United States: — " Having personally examined a large
number of coral-islands and resided eight months among the volcanic class
having shore and partially encircling reefs. I may _be permitted to state
that my own observations have impressed a conviction of the correctness

THE VOYAGE OF THE BEAGLE 501

attention of voyagers, as well as in the no less wonderful
barrier-reefs, whether encircling small islands or stretching
for hundreds of miles along the shores of a continent, are
simply explained.

It may be asked, whether I can offer any direct evidence
of the subsidence of barrier-reefs or atolls; but it must be
borne in mind how difficult it must ever be to detect a move-
ment, the tendency of which is to hide under water the part
affected. Nevertheless, at Keeling atoll I observed on all
sides of the lagoon old cocoa-nut trees undermined and fall-
ing; and in one place the foundation-posts of a shed, which
the inhabitants asserted had stood seven years before just
above high-water mark, but now was daily washed by every
tide: on inquiry I found that three earthquakes, one of them
severe, had been felt here during the last ten years. At
Vanikoro, the lagoon-channel is remarkably deep, scarcely
any alluvial soil has accumulated at the foot of the lofty
included mountains, and remarkably few islets have been
formed by the heaping of fragments and sand on the wall-
like barrier reef; these facts, and some analogous ones, led
me to believe that this island must lately have subsided and
the reef grown upwards: here again earthquakes are fre-
quent and very severe. In the Society archipelago, on the
other hand, where the lagoon-channels are almost choked up,
where much low alluvial land has accumulated, and where in
some cases long islets have been formed on the barrier-reefs
— facts all showing that the islands have not very lately
subsided — only feeble shocks are most rarely felt. In these
coral formations, where the land and water seem struggling
for mastery, it must be ever difficult to decide between the
effects of a change in the set of the tides and of a slight
subsidence: that many of these reefs and atolls are subject to
changes of some kind is certain; on some atolls the islets
appear to have increased greatly within a late period; on
others they have been partially or wholly washed away. The
inhabitants of parts of the Maldiva archipelago know the
date of the first formation of some islets ; in other parts, the
corals are now flourishing on water-washed reefs, where
holes made for graves attest the former existence of inhab-
ited land. It is difficult to believe in frequent changes in the

502 CHARLES DARWIN

tidal currents of an open ocean; whereas, we have in the
earthquakes recorded by the natives on some atolls, and in
the great fissures observed on other atolls, plain evidence of
changes and disturbances in progress in the subterranean
regions.

It is evident, on our theory, that coasts merely fringed by
reefs cannot have subsided to any perceptible amount; and
therefore they must, since the growth of their corals, either
have remained stationary or have been upheaved. Now, it
is remarkable how generally it can be shown, by the presence
of upraised organic remains, that the fringed islands have
been elevated : and so far, this is indirect evidence in favour
of our theory. I was particularly struck with this fact, when
I found, to my surprise, that the descriptions given by MM.
Quoy and Gaimard were applicable, not to reefs in general
as implied by them, but only to those of the fringing class;
my surprise, however, ceased when I afterwards found that,
by a strange chance, all the several islands visited by these
eminent naturalists, could be shown by their own statements
to have been elevated within a recent geological era.

Not only the grand features in the structure of barrier-
reefs and of atolls, and to their likeness to each other in form,
size, and other characters, are explained on the theory of
subsidence — which theory we are independently forced to
admit in the very areas in question, from the necessity of
finding bases for the corals within the requisite depth — but
many details in structure and exceptional cases can thus also
be simply explained. I will give only a few instances. In
barrier-reefs it has long been remarked with surprise, that
)he passages through the reef exactly face valleys in the
included land, even in cases where the reef is separated
from the land by a lagoon-channel so wide and so much
deeper than the actual passage itself, that it seems hardly
possible that the very small quantity of water or sediment
brought down could injure the corals on the reef. Now,
every reef of the fringing class is breached by a narrow
gateway in front of the smallest rivulet, even if dry during
the greater part of the year, for the mud, sand, or gravel,
occasionally washed down kills the corals on which it is
deposited. Consequently, when an island thus fringed sub-

THE VOYAGE OF THE BEAGLE 503

sides, though most of the narrow gateways will probably
become closed by the outward and upward growth of the
corals, yet any that are not closed (and some must always be
kept open by the sediment and impure water flowing out of
the lagoon-channel) will still continue to front exactly the
upper parts of those valleys, at the mouths of which the
original basal fringing-reef was breached.

We can easily see how an island fronted only on one side,
or on one side with one end or both ends encircled by barrier-
reefs, might after long-continued subsidence be converted
either into a single wall-like reef, or into an atoll with a
great straight spur projecting from it, or into two or three
atolls tied together by straight reefs — all of which excep-
tional cases actually occur. As the reef -building corals
require food, are preyed upon by other animals, are killed by
sediment, cannot adhere to a loose bottom, and may be easily
carried down to a depth whence they cannot spring up again,
we need feel no surprise at the reefs both of atolls and bar-
riers becoming in parts imperfect. T,he great barrier of
New Caledonia is thus imperfect and broken in many parts ;
hence, after long subsidence, this great reef would not pro-
duce one great atoll 400 miles in length, but a chain or
archipelago of atolls, of very nearly the same dimension with
those in the Maldiva archipelago. Moreover, in an atoll once
breached on opposite sides, from the likelihood of the oceanic
and tidal currents passing straight through the breaches, it
is extremely improbable that the corals, especially during
continued subsidence, would ever be able again to unite the
rim; if they did not, as the whole sank downwards, one atoll
would be divided into two or more. In the Maldiva archi-
pelago there are distinct atolls so related to each other in
position, and separated by channels either unfathomable or
very deep (the channel between Ross and Ari atolls is 150
fathoms, and that between the north and south Nillandoo
atolls is 200 fathoms in depth), that it is impossible to look
at a map of them without believing that they were once
more intimately related. And in this same archipelago,
Mahlos-Mahdoo atoll is divided by a bifurcating channel
from 100 to 132 fathoms in depth, in such a manner, that
it is scarcely possible to say whether it ought strictly to

504 CHARLES DARWIN

be called three separate atolls, or one great atoll not yet
finally divided.

I will not enter on many more details; but I must remark
that the curious structure of the northern Maldiva atolls
receives (taking into consideration the free entrance of the

- sea through their broken margins) a simple explanation in
the upward and outward growth of the corals, originally
based both on small detached reefs in their lagoons, such as
occur in common atolls, and on broken portions of the linear
marginal reef, such as bounds every atoll of the ordinary
form. I cannot refrain from once again remarking on the
singularity of these complex structures — a great sandy and
generally concave disk rises abruptly from the unfathomable
ocean, with its central expanse studded, and its edge sym-
metrically bordered with oval basins of coral-rock just
lipping the surface of the sea, sometimes clothed with vege-
tation, and each containing a lake of clear water !

One more point in detail : as in the two neighbouring archi-
pelagoes corals flourish in one and not in the other, and as
so many conditions before enumerated must affect their exist-
ence, it would be an inexplicable fact if, during the changes
to which earth, air, and water are subjected, the reef-building
corals were to keep alive for perpetuity on any one spot or
area. And as by our theory the areas including atolls and
barrier-reefs are subsiding, we ought occasionally to find
reefs both dead and submerged. In all reefs, owing to the
sediment being washed out of the lagoon-channel to leeward,
that side is least favourable to the long-continued vigorous
growth of the corals ; hence dead portions of reef not unfre-
quently occur on the leeward side; and these, though still
retaining their proper wall-like form, are now in several
instances sunk several fathoms beneath the surface. The
Chagos group appears from some cause, possibly from the
subsidence having been too rapid, at present to be much less
favourably circumstanced for the growth of reefs than for-
merly: one atoll has a portion of its marginal reef, nine miles
in length, dead and submerged; a second has only a few
quite small living points which rise to the surface; a third
and fourth are entirely dead and submerged ; a fifth is a

v mere wreck, with its structure almost obliterated. It is

THE VOYAGE OF THE BEAGLE SOS

remarkable that in all these cases, the dead reefs and portions
of reef lie at nearly the same depth, namely, from six to
eight fathoms beneath the surface, as if they had been car-
ried down by one uniform movement. One of these " half-
drowned atolls," so called by Capt. Moresby (to whom I
am indebted for much invaluable information), is of vast
size, namely, ninety nautical miles across in one direction,
and seventy miles in another line; and is in many respects
eminently curious. As by our theory it follows that new
atolls will generally be formed in each new area of sub-
sidence, two weighty objections might have been raised,
namely, that atolls must be increasing indefinitely in number ;
and secondly, that in old areas of subsidence each separate
atoll must be increasing indefinitely in thickness, if proofs
of their occasional destruction could not have been adduced.
Thus have we traced the history of these great rings of
coral-rock, from their first origin through their normal
changes, and through the occasional accidents of their exist-
ence, to their death and final obliteration.

In my volume on " Coral Formations " I have published a
map, in which I have coloured all the atolls dark-blue, the
barrier-reefs pale-blue, and the fringing reefs red. These
latter reefs have been formed whilst the land has been sta-
tionary, or, as appears from the frequent presence of upraised
organic remains, whilst it has been slowly rising: atolls and
barrier-reefs, on the other hand, have grown up during the
directly opposite movement of subsidence, which movement
must have been very gradual, and in the case of atolls so vast
in amount as to have buried every mountain-summit over
wide ocean-spaces. Now in this map we see that the reefs
tinted pale and dark-blue, which have been produced by the
same order of movement, as a general rule manifestly stand
near each other. Again we see, that the areas with the two
blue tints are of wide extent ; and that they lie separate from
extensive lines of coast coloured red, both of which circum-
stances might naturally have been inferred, on the theory of
the nature of the reefs having been governed by the nature
of the earth's movement. It deserves notice, that in more
than one instance where single red and blue circles approach

506 CHARLES DARWIN

near each other, I can show that there have been oscillations
of level; for in such cases the red or fringed circles consist
of atolls, originally by our theory formed during subsidence,
but subsequently upheaved; and on the other hand, some of
the pale-blue or encircled islands are composed of coral-rock,
which must have been uplifted to its present height before
that subsidence took place, during which the existing barrier-
reefs grew upwards.

Authors have noticed with surprise, that although atolls
are the commonest coral-structures throughout some enor-
mous oceanic tracts, they are entirely absent in other seas,
as in the West Indies: we can now at once perceive the
cause, for where there has not been subsidence, atolls cannot
have been formed; and in the case of the West Indies and
parts of the East Indies, these tracts are known to have been
rising within the recent period. The larger areas, coloured
red and blue, are all elongated ; and between the two colours
there is a degree of rude alternation, as if the rising of one
had balanced the sinking of the other. Taking into consid-
eration the proofs of recent elevation both on the fringed
coasts and on some others (for instance, in South America)
where there are no reefs, we are led to conclude that the
great continents are for the most part rising areas : and from
the nature of the coral-reefs, that the central parts of the
great oceans are sinking areas. The East Indian archipelago,
the most broken land in the world, is in most parts an area
of elevation, but surrounded and penetrated, probably in
more lines than one, by narrow areas of subsidence.

I have marked with vermilion spots all the many known
active volcanos within the limits of this same map. Their
entire absence from every one of the great subsiding areas,
coloured either pale or dark blue, is most striking and not
less so is the coincidence of the chief volcanic chains with
the parts coloured red, which we are led to conclude have
either long remained stationary, or more generally have been
recently upraised. Although a few of the vermilion spots
occur within no great distance of single circles tinted blue,
yet not one single active volcano is situated within several
hundred miles of an archipelago, or even small group of
atolls. It is, therefore, a striking fact that in the Friendly

THE VOYAGE OF THE BEAGLE 507

archipelago, which consists of a group of atolls upheaved
and since partially worn down, two volcanos, and perhaps
more, are historically known to have been in action. On the
other hand, although most of the islands in the Pacific which
are encircled by barrier-reefs, are of volcanic origin, often
with the remnants of craters still distinguishable, not one of
them is known to have ever been in eruption. Hence in these
cases it would appear, that volcanos burst forth into action
and become extinguished on the same spots, accordingly as
elevatory or subsiding movements prevail there. Numberless
facts could be adduced to prove that upraised organic remains
are common wherever there are active volcanos; but until it
could be shown that in areas of subsidence, volcanos were
either absent or inactive, the inference, however probable in
itself, that their distribution depended on the rising or falling
of the earth's surface, would have been hazardous. But now,
I think, we may freely admit this important deduction.

Taking a final view of the map, and bearing in mind the
statements made with respect to the upraised organic remains,
we must feel astonished at the vastness of the areas, which
have suffered changes in level either downwards or upwards,
within a period not geologically remote. It would appear
also, that the elevatory and subsiding movements follow
nearly the same laws. Throughout the spaces interspersed
with atolls, where not a single peak of high land has been
left above the level of the sea, the sinking must have been '
immense in amount. The sinking, moreover, whether con-
tinuous, or recurrent with intervals sufficiently long for the
corals again to bring up their living edifices to the surface,
must necessarily have been extremely slow. This conclusion
is probably the most important one which can be deduced
from the study of coral formations ; — and it is one which it is
difficult to imagine how otherwise could ever have been ar-
rived at. Nor can I quite pass over the probability of the
former existence of large archipelagoes of lofty islands,
where now only rings of coral-rock scarcely break the open
expanse of the sea, throwing some light on the distribution of
the inhabitants of the other high islands, now left standing
so immensely remote from each other in the midst of the
great oceans. The reef-constructing corals have indeed

508 CHARLES DARWIN

reared and preserved wonderful memorials of the subter-
ranean oscillations of level; we see in each barrier-reef a
proof that the land has there subsided, and in each atoll a
monument over an island now lost. We may thus, like unto
a geologist who had lived his ten thousand years and kept a
record of the passing changes, gain some insight into the
great system by which the surface of this globe has been
broken up, and land and water interchanged.

A PRIL 2Qth. — In the morning we passed round the
/J northern end of Mauritius, or the Isle of France.
From this point of view the aspect of the island
equalled the expectations raised by the many well-known
descriptions of its beautiful scenery. The sloping plain of
the Pamplemousses, interspersed with houses, and coloured
by the large fields of sugar-cane of a bright green, composed
the foreground. The brilliancy of the green was the more
remarkable because it is a colour which generally is con-
spicuous only from a very short distance. Towards the cen-
tre of the island groups of wooded mountains rose out of
this highly cultivated plain ; their summits, as so commonly
happens with ancient volcanic rocks, being jagged into the
sharpest points. Masses of white clouds were collected
around these pinnacles, as if for the sake of pleasing the
stranger's eye. The whole island, with its sloping border
and central mountains, was adorned with an air of perfect
elegance: the scenery, if I may use such an expression, ap-
peared to the sight harmonious.

I spent the greater part of the next day in walking about
the town and visiting different people. The town is of con-
siderable size, and is said to contain 20,000 inhabitants ; the
streets are very clean and regular. Although the island has
been so many years under the English Government, the gen-
eral character of the place is quite French: Englishmen

509

510 . CHARLES DARWIN

speak to their servants in French, and the shops are all
French; indeed, I should think that Calais or Boulogne was
much more Anglified. There is a very pretty little theatre,
in which operas are excellently performed. We were also
surprised at seeing large booksellers' shops, with well-stored
shelves; — music and reading bespeak our approach to the
old world of civilization; for in truth both Australia and
America are new worlds.

The various races of men walking in the streets afford the
most interesting spectacle in Port Louis. Convicts from
India are banished here for life; at present there are about
800, and they are employed in various public works. Before
seeing these people, I had no idea that the inhabitants of
India were such noble-looking figures. Their skin is ex-
tremely dark, and many of the older men had large mus-
taches and beards of a snow-white colour ; this, together with
the fire of their expression, gave them quite an imposing
aspect. The greater number had been banished for murder
and the worst crimes; others for causes which can scarcely
be considered as moral faults, such as for not obeying, from
superstitious motives, the English laws. These men are
generally quiet and well-conducted; from their outward
conduct, their cleanliness, and faithful observance of their
strange religious rites, it was impossible to look at them
with the same eyes as on our wretched convicts in New
South Wales.

May ist. — Sunday. I took a quiet walk along the sea-
coast to the north of the town. The plain in this part is quite
uncultivated; it consists of a field of black lava, smoothed
over with coarse grass and bushes, the latter being chiefly
Mimosas. The scenery may be described as intermediate in
character between that of the Galapagos and of Tahiti ; but
this will convey a definite idea to very few persons. It is a
very pleasant country, but it has not the charms of Tahiti, or „
the grandeur of Brazil. The next day I ascended La Pouce,
a mountain so called from a thumb-like projection, which
rises close behind the town to a height of 2,600 feet. The
centre of the island consists of a great platform, surrounded
by old broken basaltic mountains, with their strata dipping
seawards. The central platform, formed of comparatively

THE VOYAGE OF THE BEAGLE 511

recent streams of lava, is of an oval shape, thirteen geo-
graphical miles across, in the line of its shorter axis. The
exterior bounding mountains come into that class of struc-
tures called Craters of Elevation, which are supposed to have
been formed not like ordinary craters, but by a great and
sudden upheaval. There appears to me to be insuperable
objections to this view: on the other hand, I can hardly
believe, in this and in some other cases, that these marginal
crateriform mountains are merely the basal remnants of
immense volcanos, of which the summits either have been
blown off, or swallowed up in subterranean abysses.

From our elevated position we enjoyed an excellent view
over the island. The country on this side appears pretty well
cultivated, being divided into fields and studded with farm-
houses. I was, however, assured that of the whole land, not
more than half is yet in a productive state; if such be the
case, considering the present large export of sugar, this
island, at some future period when thickly peopled, will be
of great value. Since England has taken possession of it, a
period of only twenty-five years, the export of sugar is said
to have increased seventy-five fold. One great cause of its
prosperity is the excellent state of the roads. In the neigh-
bouring Isle of Bourbon, which remains under the French
government, the roads are still in the same miserable state
as they were here only a few years ago. Although the
French residents must have largely profited by the increased
prosperity of their island, yet the English government is far
from popular.

yd. — In the evening Captain Lloyd, the Surveyor-general,
so well known from his examination of the Isthmus of Pana-
ma, invited Mr. Stokes and myself to his country-house,
which is situated on the edge of Wilheim Plains, and about
six miles from the Port. We stayed at this delightful place
two days ; standing nearly 800 feet above the sea, the air was
cool and fresh, and on every side there were delightful walks.
Close by, a grand ravine has been worn to a depth of about
500 feet through the slightly inclined streams of lava, which
have flowed from the central platform.

^—Captain Lloyd took us to the Riviere Noire, which is
several miles to the southward, that I might examine some

512 CHARLES DARWIN

rocks of elevated coral. We passed through pleasant gar-
dens, and fine fields of sugar-cane growing amidst huge
blocks of lava. The roads were bordered by hedges of
Mimosa, and near many of the houses there were avenues
of the mango. Some of the views, where the peaked hills
and the cultivated farms were seen together, were exceed-
ingly picturesque; and we were constantly tempted to
exclaim, " How pleasant it would be to pass one's life in
such quiet abodes ! " Captain Lloyd possessed an elephant,
and he sent it half way with us, that we might enjoy a ride
in true Indian fashion. The circumstance which sur-
prised me most was its quite noiseless step. This elephant
is the only one at present on the island ; but it is said others
will be sent for.

May pth. — We sailed from Port Louis, and, calling at the
Cape of Good Hope, on the 8th of July, we arrived off St.
Helena. This island, the forbidding aspect of which has
been so often described, rises abruptly like a huge black
castle from the ocean. Near the town, as if to complete
nature's defence, small forts and guns fill up every gap in
the rugged rocks. The town runs up a flat and narrow
valley; the houses look respectable, and are interspersed
with a very few green trees. When approaching the anchor-
age there was one striking view : an irregular castle perched
on the summit of a lofty hill, and surrounded by a few scat-
tered fir-trees, boldly projected against the sky.

The next day I obtained lodgings within a stone's throw
of Napoleon's tomb;1 it was a capital central situation,
whence I could make excursions in every direction. During
the four days I stayed here, I wandered over the island from
morning to night, and examined its geological history. My
lodgings were situated at a height of about 2000 feet; here
the weather was cold and boisterous, with constant showers
of rain ; and every now and then the whole scene was veiled
in thick clouds.

1 After the volumes of eloquence which have poured forth on this sub-
ject, it is dangerous even to mention the tomb. A modern traveller, in
twelve lines, burdens the poor little island with the following titles, — it
is a grave, tomb, pyramid, cemetery, sepulchre, catacomb, sarcophagus,
minaret, and mausoleum!

THE VOYAGE OF THE BEAGLE 513

Near the coast the rough lava is quite bare : in the central
and higher parts, feldspathic rocks by their decomposition
have produced a clayey soil, which, where not covered by
vegetation, is stained in broad bands of many bright colours.
At this season, the land moistened by constant showers, pro-
duces a singularly bright green pasture, which lower and
lower down, gradually fades away and at last disappears.
In latitude 16°, and at the trifling elevation of 1500 feet, it is
surprising to behold a vegetation possessing a character
decidedly British. The hills are crowned with irregular
plantations of Scotch firs ; and the sloping banks are thickly
scattered over with thickets of gorse, covered with its bright
yellow flowers. Weeping-willows are common on the banks
of the rivulets, and the hedges are made of the blackberry,
producing its well-known fruit. When we consider that the
number of plants now found on the island is 746, and that
out of these fifty-two alone are indigenous species, the rest
having been imported, and most of them from England,
vre see the reason of the British character of the vegetation.
Many of these English plants appear to flourish better than
in their native country ; some also from the opposite quarter
of Australia succeed remarkably well. The many imported
species must have destroyed some of the native kinds; and
it is only on the highest and steepest ridges that the indig-
enous Flora is now predominant.

The English, or rather Welsh character of the scenery, is
kept up by the numerous cottages and small white houses;
some buried at the bottom of the deepest valleys, and others
mounted on the crests of the lofty hills. Some of the views
are striking, for instance that from near Sir W. Doveton's
house, where the bold peak called Lot is seen over a dark
wood of firs, the whole being backed by the red water-worn
mountains of the southern coast. On viewing the island
from an eminence, the first circumstance which strikes one,
is the number of the roads and forts: the labour bestowed
on the public works, if one forgets its character as a prison,
seems out of all proportion to its extent or value. There
is so little level or useful land, that it seems surprising how
so many people, about 5000, can subsist here. The lower
orders, or the emancipated slaves, are I believe extremely
VOL. xxix — Q HC

514 CHARLES DARWIN

poor : they complain of the want of work. From the reduc-
tion in the number of public servants, owing to the island
having been given up by the East Indian Company, and the
consequent emigration of many of the richer people, the
poverty probably will increase. The chief food of the work-
ing class is rice with a little salt meat; as neither of these
articles are the products of the island, but must be purchased
with money, the low wages tell heavily on the poor people.
Now that the people are blessed with freedom, a right which
I believe they value fully, it seems probable that their num-
bers will quickly increase: if so, what is to become of the
little state of St. Helena?

My guide was an elderly man, who had been a goatherd
when a boy, and knew every step amongst the rocks. He
was of a race many times crossed, and although with a
dusky skin, he had not the disagreeable expression of a
mulatto. He was a very civil, quiet old man, and such
appears the character of the greater number of the lower
classes. It was strange to my ears to hear a man, nearly
white and respectably dressed, talking with indifference of
the times when he was a slave. With my companion, who
carried our dinners and a horn of water, which is quite
necessary, as all the water in the lower valleys is saline, I
every day took long walks.

Beneath the upper and central green circle, the wild val-
leys are quite desolate and untenanted. Here, to the geolo-
gist, there were scenes of high interest, showing successive
changes and complicated disturbances. According to my
views, St. Helena has existed as an island from a very
remote epoch: some obscure proofs, however, of the eleva-
tion of the land are still extant. I believe that the central
and highest peaks form parts of the rim of a great crater,
the southern half of which has been entirely removed by the
waves of the sea: there is, moreover, an external wall of
black basaltic rocks, like the coast-mountains of Mauritius,
which are older than the central volcanic streams. On the
higher parts of the island, considerable numbers of a shell,
long thought to be a marine species, occur imbedded in the
soil.

It proved to be a Cochlogena, or land-shell of a very

THE VOYAGE OF THE BEAGLE 515

peculiar form;1 with it I found six other kinds; and in
another spot an eighth species. It is remarkable that none
of them are now found living. Their extinction has prob-
ably been caused by the entire destruction of the woods, and
the consequent loss of food and shelter, which occurred
during the early part of the last century.

The history of the changes, which the elevated plains of
Longwood and Deadwood have undergone, as given in Gen-
eral Beatson's account of the island, is extremely curious.
Both plains, it is said in former times were covered with
wood, and were therefore called the Great Wood. So late
as the year 1716 there were many trees, but in 1724 the old
trees had mostly fallen; and as goats and hogs had been
suffered to range about, all the young trees had been killed.
It appears also from the official records, that the trees were
unexpectedly, some years afterwards, succeeded by a wire
grass which spread over the whole surface.* General Beat-
son adds that now this plain " is covered with fine sward, and
is become the finest piece of pasture on the island." The
extent of surface, probably covered by wood at a former
period, is estimated at no less than two thousand acres; at
the present day scarcely a single tree can be found there. It
is also said that in 1709 there were quantities of dead trees
in Sandy Bay; this place is now so utterly desert, that noth-
ing but so well attested an account could have made me believe
that they could ever have grown there. The fact, that the
goats and hogs destroyed all the young trees as they sprang
up, and that in the course of time the old ones, which were
safe from their attacks, perished from age, seems clearly
made out. Goats were introduced in the year 1502; eighty-
six years afterwards, in the time of Cavendish, it is known
that they were exceedingly numerous. More than a century
afterwards, in 1731, when the evil was complete and irre-
trievable, an order was issued that all stray animals should
be destroyed. It is very interesting thus to find, that the
arrival of animals at St. Helena in 1501, did not change the
whole aspect of the island, until a period of two hundred

a It deserves notice, that all the many specimens of this shell found by
me in one spot, differ as a marked variety, from another set of specimens
procured from a different spot.

516 CHARLES DARWIN

and twenty years had elapsed : for the goats were introduced
in 1502, and in 1724 it is said " the old trees had mostly
fallen." There can be little doubt that this great change in
the vegetation affected not only the land-shells, causing eight
species to become extinct, but likewise a multitude of insects.
St. Helena, situated so remote from any continent, in the
midst of a great ocean, and possessing a unique Flora, ex-
cites our curiosity. The eight land-shells, though now extinct,
and one living Succinea, are peculiar species found nowhere
else. Mr. Cuming, however, informs me that an English
Helix is common here, its eggs no doubt having been im-
ported in some of the many introduced plants. Mr. Cuming
collected on the coast sixteen species of sea-shells, of which
seven, as far as he knows, are confined to this island. Birds
and insects,* as might have been expected, are very few in
number ; indeed I believe all the birds have been introduced
within late years. Partridges and pheasants are tolerably
abundant; the island is much too English not to be subject
to strict game-laws. I was told of a more unjust sacrifice to

* Among these few insects, I was surprised to find a small Aphodius
(nov. spec.) and an Oryctes, both extremely numerous under dung. When
the island was discovered it certainly possessed no quadruped, excepting
perhaps a mouse: it becomes, therefore, a difficult point to ascertain,
whether these stercovorous insects have since been imported by accident,
or if aborigines, on what food they formerly subsisted. On the banks of
the Plata, where, from the vast number of cattle and horses, the fine plains
of turf are richly manured, it is vain to seek the many kinds of dung-
feeding beetles, which occur so abundantly in Europe. I observed only an
Oryctes (the insects of this genus in Europe generally feed on decayed
vegetable matter) and two species of Phanaeus, common in such situations.
On the opposite side of the Cordillera in Chiloe, another species of Pha-
naeus is exceedingly abundant, and it buries the dung of the cattle in large
earthen balls beneath the ground. There is reason to believe that the
genus Phanaeus, before the introduction of cattle, acted as scavengers to
man. In Europe, beetles, which find support in the matter which has
already contributed towards the life of other and larger animals, are so
numerous that there must be considerably more than one hundred different
specie_s. Considering this, and observing wha_t a quantity of food of this
kind is lost on the plains of La Plata, I imagined I saw an instance where
man had disturbed that chain, by which so many animals are linked
together in their native country. In Van Diemen's Land, however, I
found four species of Onthophagus, two of Aphodius, and one of a third

fen us, very abundantly under the dung of cows; yet these latter animals
ad been then introduced only thirty-three years. Previously to that time
the kangaroo and some other small animals were the only quadrupeds; and
their dung is of a very different quality from that of their successors intro-
duced by man. In England the greater number of stercovorous beetles
are confined in their appetites; that is, they do not depend indifferently
on any quadruped for the means of subsistence. The change, therefore,
in habits which must have taken place in Van Diemen's Land is highly
remarkable. I am indebted to the Rev. F. W. Hope, who, I hope, will
permit me to call him my master in Entomology, for giving me the names
of the foregoing insects.

THE VOYAGE OF THE BEAGLE 517

such ordinances than I ever heard of even in England. The
poor people formerly used to burn a plant, which grows on the
coast-rocks, and export the soda from its ashes; but a per-
emptory order came out prohibiting this practice, and giving
as a reason that the partridges would have nowhere to build.

In my walks I passed more than once over the grassy plain
bounded by deep valleys, on which Longwood stands.
Viewed from a short distance, it appears like a respectable
gentleman's country-seat. In front there are a few culti-
vated fields, and beyond them the smooth hill of coloured
rocks called the Flagstaff, and the rugged square black mass
of the Barn. On the whole the view was rather bleak and
uninteresting. The only inconvenience I suffered during my
walks was from the impetuous winds. One day I noticed
a curious circumstance ; standing on the edge of a plain, ter-
minated by a great cliff of about a thousand feet in depth,
I saw at the distance of a few yards right to windward, some
tern, struggling against a very strong breeze, whilst, where
I stood, the air was quite calm. Approaching close to the
brink, where the current seemed to be deflected upwards
from the face of the cliff, I stretched out my arm, and
immediately felt the full force of the wind: an invisible
barrier, two yards in width, separated perfectly calm air
from a strong blast.

I so much enjoyed my rambles among the rocks and moun-
tains of St. Helena, that I felt almost sorry on the morning
of the I4th to descend to the town. Before noon I was on
board, and the Beagle made sail.

On the igth of July we reached Ascension. Those who
have beheld a volcanic island, situated under an arid climate,
will at once be able to picture to themselves the appearance
of Ascension. They will imagine smooth conical hills of a
bright red colour, with their summits generally truncated,
rising separately out of a level surface of black rugged lava.
A principal mound in the centre of the island, seems the
father of the lesser cones. It is called Green Hill: its
name being taken from the faintest tinge of that colour,
which at this time of the year is barely perceptible from the
anchorage. To complete the desolate scene, the black rocks
on the coast are lashed by a wild and turbulent sea.

518 CHARLES DARWIN

The settlement is near the beach; it consists of several
houses and barracks placed irregularly, but well built of
white freestone. The only inhabitants are marines, and some
negroes liberated from slave-ships, who are paid and victu-
alled by government. There is not a private person on the
island. Many of the marines appeared well contented with
their situation ; they think it better to serve their one-and-
twenty years on shore, let it be what it may, than in a ship;
in this choice, if I were a marine, I should most heartily
agree.

The next morning I ascended Green Hill, 2840 feet high,
and thence walked across the island to the windward point.
A good cart-road leads from the coast-settlement to the
houses, gardens, and fields, placed near the summit of the
central mountain. On the roadside there are milestones, and
likewise cisterns, where each thirsty passer-by can drink
some good water. Similar care is displayed in each part of the
establishment, and especially in the management of the
springs, so that a single drop of water may not be lost: in-
deed the whole island may be compared to a huge ship kept
in first-rate order. I could not help, when admiring the
active industry, which had created such effects out of such
means, at the same time regretting that it had been wasted on
so poor and trifling an end. M. Lesson has remarked with
justice, that the English nation would have thought of mak-
ing the island of Ascension a productive spot; any other
people would have held it as a mere fortress in the ocean.

Near this coast nothing grows; further inland, an occa-
sional green castor-oil plant, and a few grasshoppers, true
friends of the desert, may be met with. Some grass is scat-
tered over the surface of the central elevated region, and the
whole much resembles the worse parts of the Welsh moun-
tains. But scanty as the pasture appears, about six hundred
sheep, many goats, a few cows and horses, all thrive well on
it. Of native animals, land-crabs and rats swarm in num-
bers. Whether the rat is really indigenous, may well be
doubted; there are two varieties as described by Mr. Water-
house; one is of a black colour, with fine glossy fur, and
lives on the grassy summit ; the other is brown-coloured and
less glossy, with longer hairs, and lives near the settlement

THE VOYAGE OF THE BEAGLE 519

on the coast. Both these varieties are one-third smaller than
the common black rat (M. rattus) ; and they differ from it
both in the colour and character of their fur, but in no
other essential respect. I can hardly doubt that these rats
(like the common mouse, which has also run wild) have
been imported, and, as at the Galapagos, have varied from
the effect of the new conditions to which they have been
exposed: hence the variety on the summit of the island
differs from that on the coast. Of native birds there are
none; but the guinea-fowl, imported from the Cape de
Verd Islands, is abundant, and the common fowl has like-
wise run wild. Some cats, which were originally turned out
to destroy the rats and mice, have increased, so as to be-
come a great plague. The island is entirely without trees,
in which, and in every other respect, it is very far inferior
to St. Helena.

One of my excursions took me towards the S. W. extrem-
ity of the island. The day was clear and hot, and I saw the
island, not smiling with beauty, but staring with naked hide-
ousness. The lava streams are covered with hummocks, and
are rugged to a degree which, geologically speaking, is not
of easy explanation. The intervening spaces are concealed
with layers of pumice, ashes and volcanic tuff. Whilst pass-
ing this end of the island at sea, I could not imagine what
the white patches were with which the whole plain was
mottled ; I now found that they were seafowl, sleeping in such
full confidence, that even in midday a man could walk up
and seize hold of them. These birds were the only living
creatures I saw during the whole day. On the beach a great
surf, although the breeze was light, came tumbling over
the broken lava rocks.

The geology of this island is in many respects interesting.
In several places I noticed volcanic bombs, that is, masses of
lava which have been shot through the air whilst fluid, and
have consequently assumed a spherical or pear-shape. Not
only their external form, but, in several cases, their internal
structure shows in a very curious manner that they have re-
volved in their aerial course. The internal structure of one
of these bombs, when broken, is represented very accurately
in the woodcut. The central part is coarsely cellular, the

520

CHARLES DARWIN

cells decreasing in size towards the exterior; where there
is a shell-like case about the third of an inch in thickness,
of compact stone, which again is overlaid by the outside
crust of finely cellular lava. I think there can be little
doubt, first that the external crust cooled rapidly in the state
in which we now see it; secondly, that the still fluid lava
within, was packed by the centrifugal force, generated by

the revolving of the bomb, against the external cooled
crust, and so produced the solid shell of stone; and lastly,
that the centrifugal force, by relieving the pressure in the
more central parts of the bomb, allowed the heated vapours
to expand their cells, thus forming the coarse cellular mass
of the centre.

A hill, formed of the older series of volcanic rocks, and
which has been incorrectly considered as the crater of a vol-
cano, is remarkable from its broad, slightly hollowed, and
circular summit having been filled up with many successive
layers of ashes and fine scoriae. These saucer-shaped layers
crop out on the margin, forming perfect rings of many dif-
ferent colours, giving to the summit a most fantastic appear-
ance; one of these rings is white and broad, and resembles

THE VOYAGE OF THE BEAGLE 521

a course round which horses have been exercised ; hence the
hill has been called the Devil's Riding School. I brought away
specimens of one of the tufaceous layers of a pinkish colour
and it is a most extraordinary fact, that Professor Ehren-
berg" finds it almost wholly composed of matter which has
been organized : he detects in it some siliceous-shielded fresh-
water infusoria, and no less than twenty-five different kinds
of the siliceous tissue of plants, chiefly of grasses. From
the absence of all carbonaceous matter, Professor Ehrenberg
believes that these organic bodies have passed through the
volcanic fire, and have been erupted in the state in which
we now see them. The appearance of the layers induced me
to believe that they had been deposited under water, though
from the extreme dryness of the climate I was forced to im-
agine, that torrents of rain had probably fallen during some
great eruption, and that thus a temporary lake had been
formed into which the ashes fell. But it may now be sus-
pected that the lake was not a temporary one. Anyhow, we
may feel sure, that at some former epoch the climate and
productions of Ascension were very different from what
th?y now are. Where on the face of the earth can we find
a spot, on which close investigation will not discover signs
of that endless cycle of change, to which this earth has been,
is, and will be subjected?

On leaving Ascension, we sailed for Bahia, on the coast
of Brazil, in order to complete the chronometrical measure-
ment of the world. We arrived there on August 1st, and
stayed four days, during which I took several long walks.
I was glad to find my enjoyment in tropical scenery had not
decreased from the want of novelty, even in the slightest
degree. The elements of the scenery are so simple, that they
are worth mentioning, as a proof on what trifling circum-
stances exquisite natural beauty depends.

The country may be described as a level plain of about
three hundred feet in elevation, which in all parts has been
worn into flat-bottomed valleys. This structure is remark-
able in a granitic land, but is nearly universal in all those
softer formations of which plains are usually composed.
The whole surface is covered by various kinds of stately

6 Monats. der Konig. Akad. d. Wiss. zu Berlin. Vom April, 1845.

522 CHARLES DARWIN

trees, interspersed with patches of cultivated ground, out
of which houses, convents, and chapels arise. It must be
remembered that within the tropics, the wild luxuriance of
nature is not lost even in the vicinity of large cities: for
the natural vegetation of the hedges and hill-sides over-
powers in picturesque effect the artificial labour of man.
Hence, there are only a few spots where the bright red
soil affords a strong contrast with the universal clothing
of green. From the edges of the plain there are distant
views either of the ocean, or of the great Bay with its
low-wooded shores, and on which numerous boats and canoes
show their white sails. Excepting from these points, the
scene is extremely limited; following the level pathways,
on each hand, only glimpses into the wooded valleys below
can be obtained. The houses I may add, and especially the
sacred edifices, are built in a peculiar and rather fantastic
style of architecture. They are all whitewashed; so that
when illumined by the brilliant sun of midday, and as seen
against the pale blue sky of the horizon, they stand out more
like shadows than real buildings.

Such are the elements of the scenery, but it is a hopeless
attempt to paint the general effect. Learned naturalists de-
scribe these scenes of the tropics by naming a multitude of
objects, and mentioning some characteristic feature of each.
To a learned traveller this possibly may communicate some
definite ideas : but who else from seeing a plant in an herba-
rium can imagine its appearance when growing in its native
soil? Who from seeing choice plants in a hothouse, can
magnify some into the dimensions of forest trees, and crowd
others into an entangled jungle? Who when examining in
the cabinet of the entomologist the gay exotic butter-
flies, and singular cicadas, will associate with these lifeless
objects, the ceaseless harsh music of the latter, and the
lazy flight of the former, — the sure accompaniments of the
still, glowing noonday of the tropics ? It is when the sun has
attained its greatest height, that such scenes should be
viewed: then the dense splendid foliage of the mango hides
the ground with its darkest shade, whilst the upper branches
are rendered from the profusion of light of the most bril-
liant green. In the temperate zones the case is different — the

THE VOYAGE OF THE BEAGLE 523

vegetation there is not so dark or so rich, and hence the
rays of the declining sun, tinged of a red, purple, or bright
yellow color, add most to the beauties of those climes.

When quietly walking along the shady pathways, and ad-
miring each successive view, I wished to find language to
express my ideas. Epithet after epithet was found too weak
to convey to those who have not visited the intertropical
regions, the sensation of delight which the mind experiences.
I have said that the plants in a hothouse fail to communicate
a just idea of the vegetation, yet I must recur to it. The land
is one great wild, untidy, luxuriant hothouse, made by
Nature for herself, but taken possession of by man, who has
studded it with gay houses and formal gardens. How great
would be the desire in every admirer of nature to behold,
if such were possible, the scenery of another planet! yet
to every person in Europe, it may be truly said, that at
the distance of only a few degrees from his native soil, the
glories of another world are opened to him. In my last
walk I stopped again and again to gaze on these beauties, and
endeavoured to fix in my mind for ever, an impression which
at the time I knew sooner or later must fail. The form of
the orange-tree, the cocoa-nut, the palm, the mango, the tree-
fern, the banana, will remain clear and separate; but the
thousand beauties which unite these into one perfect scene
must fade away; yet they will leave, like a tale heard in
childhood, a picture full of indistinct, but most beautiful
figures.

August 6th. — In the afternoon we stood out to sea, with
the intention of making a direct course to the Cape de Verd
Islands. Unfavourable winds, however, delayed us, and on
the I2th we ran into Pernambuco, — a large city on the
coast of Brazil, in latitude 8° south. We anchored outside
the reef; but in a short time a pilot came on board and
took us into the inner harbour, where we lay close to the
town.

Pernambuco is built on some narrow and low sand-banks,
which are separated from each other by shoal channels of
salt water. The three parts of the town are connected to-
gether by two long bridges built on wooden piles. The
town is in all parts disgusting, the streets being narrow, ill-

524 CHARLES DARWIN

paved, and filthy; the houses, tall and gloomy. The season
of heavy rains had hardly come to an end, and hence the
surrounding country, which is scarcely raised above the
level of the sea, was flooded with water; and I failed in
all my attempts to take walks.

The flat swampy land on which Pernambuco stands is sur-
rounded, at the distance of a few miles, by a semicircle of
low hills, or rather by the edge of a country elevated per-
haps two hundred feet above the sea. The old city of
Olinda stands on one extremity of this range. One day I
took a canoe, and proceeded up one of the channels to visit
it; I found the old town from its situation both sweeter and
cleaner than that of Pernambuco. I must here commemorate
what happened for the first time during our nearly five
years' wandering, namely, having met with a want of polite-
ness. I was refused in a sullen manner at two different
houses, and obtained with difficulty from a third, per-
mission to pass through their gardens to an uncultivated hill,
for the purpose of viewing the country. I feel glad that
this happened in the land of the Brazilians, for I bear
them no good will — a land also of slavery, and therefore
of moral debasement. A Spaniard would have felt ashamed
at the very thought of refusing such a request, or of
behaving to a stranger with rudeness. The channel by which
we went to and returned from Olinda, was bordered on each
side by mangroves, which sprang like a miniature forest out
of the greasy mud-banks. The bright green colour of these
bushes always reminded me of the rank grass in a church-
yard: both are nourished by putrid exhalations; the one
speaks of death past, and the other too often of death
to come.

The most curious object which I saw in this neighbour-
hood, was the reef that forms the harbour. I doubt whether
in the whole world any other natural structure has so arti-
ficial an appearance.6 It runs for a length of several miles in
an absolutely straight line, parallel to, and not far distant
from, the shore. It varies in width from thirty to sixty
yards, and its surface is level and smooth ; it is composed of

6 I have described this Bar in detail, in the Lend, and Edin. Phil. Mag.,
vol. xix. (1841), p. 257.

THE VOYAGE OF THE BEAGLE 525

obscurely stratified hard sandstone. At high water the waves
break over it; at low water its summit is left dry, and it
might then be mistaken for a breakwater erected by Cyclo-
pean workmen. On this coast the currents of the sea tend
to throw up in front of the land, long spits and bars of
loose sand, and on one of these, part of the town of Per-
nambuco stands. In former times a long spit of this nature
seems to have become consolidated by the percolation of
calcareous matter, and afterwards to have been gradually
upheaved ; the outer and loose parts during this process hav-
ing been worn away by the action of the sea, and the solid
nucleus left as we now see it. Although night and day the
waves of the open Atlantic, turbid with sediment, are
driven against the steep outside edges of this wall of stone,
yet the oldest pilots know of no tradition of any change in its
appearance. This durability is much the most curious fact
in its history : it is due to a tough layer, a few inches thick,
of calcareous matter, wholly formed by the successive
growth and death of the small shells of Serpulae, together
with some few barnacles and nulliporae. These nulliporae,
which are hard, very simply-organized sea-plants, play an
analogous and important part in protecting the upper sur-
faces of coral-reefs, behind and within the breakers, where
the true corals, during the outward growth of the mass,
become killed by exposure to the sun and air. These in-
significant organic beings, especially the Serpulae, have done
good service to the people of Pernambuco ; for without their
protective aid the bar of sandstone would inevitably have
been long ago worn away and without the bar, there would
have been no harbour.

On the iQth of August we finally left the shores of Brazil.
I thank God, I shall never again visit a slave-country. To
this day, if I hear a distant scream, it recalls with painful
vividness my feelings, when passing a house near Pernam-
buco, I heard the most pitiable moans, and could not but
suspect that some poor slave was being tortured, yet knew
that I was as powerless as a child even to remonstrate. I sus-
pected that these moans were from a. tortured slave, for I
was told that this was the case in another instance. Near
Rio de Janeiro I lived opposite to an old lady, who kept

526 CHARLES DARWIN

screws to crush the fingers of her female slaves. I have
stayed in a house where a young household mulatto, daily
and hourly, was reviled, beaten, and persecuted enough to
break the spirit of the lowest animal. I have seen a little
boy, six or seven years old, struck thrice with a horse-whip
(before I could interfere) on his naked head, for having
handed me a glass of water not quite clean; I saw his
father tremble at a mere glance from his master's eye.
These latter cruelties were witnessed by me in a Spanish
colony, in which it has always been said, that slaves are
better treated than by the Portuguese, English, or other
European nations. I have seen at Rio de Janeiro a powerful
negro afraid to ward off a blow directed, as he thought, at his
face. I was present when a kind-hearted man was on the
point of separating forever the men, women, and little
children of a large number of families who had long lived
together. I will not even allude to the many heart-sickening
atrocities which I authentically heard of; — nor would I have
mentioned the above revolting details, had I not met with sev-
eral people, so blinded by the constitutional gaiety of the negro
as to speak of slavery as a tolerable evil. Such people have
generally visited at the houses of the upper classes, where
the domestic slaves are usually well treated; and they have
not, like myself, lived amongst the lower classes. Such
inquirers will ask slaves about their condition; they forget
that the slave must indeed be dull, who does not calculate
on the chance of his answer reaching his master's ears.

It is argued that self-interest will prevent excessive cru-
elty ; as if self-interest protected our domestic animals, which
are far less likely than degraded slaves, to stir up the rage
of their savage masters. It is an argument long since pro-
tested against with noble feeling, and strikingly exemplified,
by the ever-illustrious Humboldt. It is often attempted to
palliate slavery by comparing the state of slaves with our
poorer countrymen: if the misery of our poor be caused
not by the laws of nature, but by our institutions, great is
our sin ; but how this bears on slavery, I cannot see ; as well
might the use of the thumb-screw be defended in one
land, by showing that men in another land suffered from
some dreadful disease. Those who look tenderly at the slave

THE VOYAGE OF THE BEAGLE 527

owner, and with a cold heart at the slave, never seem to put
themselves into the position of the latter; what a cheerless
prospect, with not even a hope of change ! picture to your-
self the chance, ever hanging over you, of your wife and
your little children — those objects which nature urges even
the slave to call his own — being torn from you and sold
like beasts to the first bidder! And these deeds are done
and palliated by men, who profess to love their neighbours
as themselves, who believe in God, and pray that his Will be
done on earth ! It makes one's blood boil, yet heart tremble,
to think that we Englishmen and our American descendants,
with their boastful cry of liberty, have been and are so
guilty : but it is a consolation to reflect, that we at least have
made a greater sacrifice, than ever made by any nation,
to expiate our sin.

On the last day of August we anchored for the second time
at Porto Praya in the Cape de Verd archipelago; thence we
proceeded to the Azores, where we stayed six days. On the
2nd of October we made the shores of England; and at Fal-
mouth I left the Beagle, having lived on board the good little
vessel nearly five years.

Our Voyage having come to an end, I will take a short
retrospect of the advantages and disadvantages, the pains
and pleasures, of our circumnavigation of the world. If a
person asked my advice, before undertaking a long voyage,
my answer would depend upon his possessing a decided taste
for some branch of knowledge, which could by this means be
advanced. No doubt it is a high satisfaction to behold various
countries and the many races of mankind, but the pleasures
gained at the time do not counterbalance the evils. It is
necessary to look forward to a harvest, however distant
that may be, when some fruit will be reaped, some good
effected.

Many of the losses which must be experienced are obvious ;
such as that of the society of every old friend, and of the
sight of those places with which every dearest remembrance
is so intimately connected. These losses, however, are at
the time partly relieved by the exhaustless delight of antici-

528 CHARLES DARWIN

pating the long wished-for day of return. If, as poets say,
life is a dream, I am sure in a voyage these are the visions
which best serve to pass away the long night. Other losses,
although not at first felt, tell heavily after a period: these
are the want of room, of seclusion, of rest; the jading feel-
ing of constant hurry ; the privation of small luxuries, the loss
of domestic society and even of music and the other pleasures
of imagination. When such trifles are mentioned, it is
evident that the real grievances, excepting from accidents, of
a sea-life are at an end. The short space of sixty years has
made an astonishing difference in the facility of distant
navigation. Even in the time of Cook, a man who left
his fireside for such expeditions underwent severe privations.
A yacht now, with every luxury of life, can circumnavigate
the globe. Besides the vast improvements in ships and
naval resources, the whole western shores of America are
thrown open, and Australia has become the capital of a
rising continent. How different are the circumstances to a
man shipwrecked at the present day in the Pacific, to what
they were in the time of Cook! Since his voyage a hemi-
sphere has been added to the civilized world.

If a person suffer much from sea-sickness, let him weigh
it heavily in the balance. I speak from experience : it is no
trifling evil, cured in a week. If, on the other hand, he take
pleasure in naval tactics, he will assuredly have full scope
for his taste. But it must be borne in mind, how large a
proportion of the time, during a long voyage, is spent on
the water, as compared with the days in harbour. And what
are the boasted glories of the illimitable ocean. A tedious
', waste, a desert of water, as the Arabian calls it. No doubt
there are some delightful scenes. A moonlight night, with
the clear heavens and the dark glittering sea, and the white
sails filled by the soft air of a gently blowing trade-wind, a
dead calm, with the heaving surface polished like a mirror,
and all still except the occasional flapping of the canvas.
It is well once to behold a squall with its rising arch and
coming fury, or the heavy gale of wind and mountainous
waves. I confess, however, my imagination had painted
something more grand, more terrific in the full-grown storm.
It is an incomparably finer spectacle when beheld on shore,

THE VOYAGE OF THE BEAGLE S2S

where the waving trees, the wild flight of the birds, the
dark shadows and bright lights, the rushing of the torrents
all proclaim the strife of the unloosed elements. At sea
the albatross and little petrel fly as if the storm were their
proper sphere, the water rises and sinks as if fulfilling its
usual task, the ship alone and its inhabitants seem the objects
of wrath. On a forlorn and weather-beaten coast, the scene
is indeed different, but the feelings partake more of horror
than of wild delight.

Let us now look at the brighter side of the past time. The
pleasure derived from beholding the scenery and the general
aspect of the various countries we have visited, has decidedly
been the most constant and highest source of enjoyment. It
is probable that the picturesque beauty of many parts of Eu-
rope exceeds anything which we beheld. But there is a
growing pleasure in comparing the character of the scenery
in different countries, which to a certain degree is distinct
from merely admiring its beauty. It depends chiefly on an
acquaintance with the individual parts of each view. I am
strongly induced to believe that as in music, the person who
understands every note will, if he also possesses a proper
taste, more thoroughly enjoy the whole, so he who examines
each part of a fine view, may also thoroughly comprehend
the full and combined effect. Hence, a traveller should be
a botanist, for in all views plants form the chief embellish-
ment. Group masses of naked rock, even in the wildest
forms, and they may for a time afford a sublime spectacle,
but they will soon grow monotonous. Paint them with bright
and varied colours, as in Northern Chile, they will become
fantastic; clothe them with vegetation, they must form a
decent, if not a beautiful picture.

When I say that the scenery of parts of Europe is probably
superior to anything which we beheld, I except, as a class by
itself, that of the intertropical zones. The two classes cannot
be compared together; but I have already often enlarged on
the grandeur of those regions. As the force of impressions
generally depends on preconceived ideas, I may add, that
mine were taken from the vivid descriptions in the Personal
Narrative of Humboldt, which far exceed in merit anything
else which I have read. Yet with these high-wrought ideas,

530 CHARLES DARWIN

my feelings were far from partaking of a tinge of disappoint-
ment on my first and final landing on the shores of Brazil.

Among the scenes which are deeply impressed on my mind,
none exceed in sublimity the primeval forests undefaced by
the hand of man ; whether those of Brazil, where the powers
of Life are predominant, or those of Tierra del Fuego,
where Death and Decay prevail. Both are temples filled with
the varied productions of the God of Nature: — no one can
stand in these solitudes unmoved, and not feel that there is
more in man than the mere breath of his body. In calling
up images of the past, I find that the plains of Patagonia
frequently cross before my eyes; yet these plains are pro-
nounced by all wretched and useless. They can be described
only by negative characters; without habitations, without
water, without trees, without mountains, they support merely
a few dwarf plants. Why, then, and the case is not peculiar
to myself, have these arid wastes taken so firm a hold on
my memory ? Why have not the still more level, the greener
and more fertile Pampas, which are serviceable to mankind,
produced an equal impression? I can scarcely analyze these
feelings : but it must be partly owing to the free scope given
to the imagination. The plains of Patagonia are boundless,
for they are scarcely passable, and hence unknown: they
bear the stamp of having lasted, as they are now, for ages,
and there appears no limit to their duration through future
time. If, as the ancients supposed, the flat earth was sur-
rounded by an impassable breadth of water, or by deserts
heated to an intolerable excess, who would not look at these
last boundaries to man's knowledge with deep but ill-defined
sensations ?

Lastly, of natural scenery, the views from lofty mountains,
through certainly in one sense not beautiful, are very memo-
rable. When looking down from the highest crest of the
Cordillera, the mind, undisturbed by minute details, was
filled with the stupendous dimensions of the surrounding
masses.

Of individual objects, perhaps nothing is more certain to
create astonishment than the first sight in his native haunt of
a barbarian — of man in his lowest and most savage state.
One's mind hurries back over past centuries, and then asks.

THE VOYAGE OF THE BEAGLE 531

could our progenitors have been men like these? — men,
whose very signs and expressions are less intelligible to us
than those of the domesticated animals; men, who do not
possess the instinct of those animals, nor yet appear to boast
of human reason, or at least of arts consequent on that
reason. I do not believe it is possible to describe or paint
the difference between savage and civilized man. It is
the difference between a wild and tame animal: and part
of the interest in beholding a savage, is the same which
would lead every one to desire to see the lion in his desert,
the tiger tearing his prey in the jungle, or the rhinoceros
wandering over the wild plains of Africa.

Among the other most remarkable spectacles which we
have beheld, may be ranked, the Southern Cross, the cloud
of Magellan, and the other constellations of the southern
hemisphere — the water-spout — the glacier leading its blue
stream of ice, over-hanging the sea in a bold precipice — a
lagoon-island raised by the reef-building corals — an active
volcano — and the overwhelming effects of a violent earth-
quake. These latter phenomena, perhaps, possess for me a
peculiar interest, from their intimate connection with the
geological structure of the world. The earthquake, however,
must be to every one a most impressive event: the earth,
considered from our earliest childhood as the type of solid-
ity, has oscillated like a thin crust beneath our feet; and
in seeing the laboured works of man in a moment over-
thrown, we feel the insignificance of his boasted power.

It has been said, that the love of the chase is an inherent
delight in man — a relic of an instinctive passion. If so, I
am sure the pleasure of living in the open air, with the sky
for a roof and the ground for a table, is part of the same
feeling; it is the savage returning to his wild and native
habits. I always look back to our boat cruises, and my land
journeys, when through unfrequented countries, with an ex-
treme delight, which no scenes of civilization could have
created. I do not doubt that every traveller must remember
the glowing sense of happiness which he experienced, when
he first breathed in a foreign clime, where the civilized man
had seldom or never trod.

There are several other sources of enjoyment in a long

532 CHARLES DARWIN

voyage, which are of a more reasonable nature. The map
of the world ceases to be a blank; it becomes a picture full
of the most varied and animated figures. Each part assumes
its proper dimensions: continents are not looked at in the
light of islands, or islands considered as mere specks, which
are, in truth, larger than many kingdoms of Europe. Africa,
or North and South America, are well-sounding names, and
easily pronounced; but it is not until having sailed for
weeks along small portions of their shores, that one is thor-
oughly convinced what vast spaces on our immense world
these names imply.

From seeing the present state, it is impossible not to look
forward with high expectations to the future progress of
nearly an entire hemisphere. The march of improvement,
consequent on the introduction of Christianity throughout
the South Sea, probably stands by itself in the records of
history. It is the more striking when we remember that only
sixty years since, Cook, whose excellent judgment none will
dispute, could foresee no prospect of a change. Yet these
changes have now been effected by the philanthropic spirit
of the British nation.

In the same quarter of the globe Australia is rising, or
indeed may be said to have risen, into a grand centre of
civilization, which, at some not very remote period, will rule
as empress over the southern hemisphere. It is impossible
for an Englishman to behold these distant colonies, without
a high pride and satisfaction. To hoist the British flag,
seems to draw with it as a certain consequence, wealth, pros-
perity, and civilization.

In conclusion, it appears to me that nothing can be more
improving to a young naturalist, than a journey in distant
countries. It both sharpens, and partly allays that want and
craving, which, as Sir J. Herschel remarks, a man experi-
ences although every corporeal sense be fully satisfied. The
excitement from the novelty of objects, and the chance of
success, stimulate him to increased activity. Moreover, as a
number of isolated facts soon become uninteresting, the
habit of comparison leads to generalization. On the other
hand, as the traveller stays but a short time in each place,
his descriptions must generally consist of mere sketches, in-

THE VOYAGE OF THE BEAGLE 533

stead of detailed observations. Hence arises, as I have found
to my cost, a constant tendency to fill up the wide gaps of
knowledge, by inaccurate and superficial hypotheses.

But I have too deeply enjoyed the voyage, not to recom-
mend any naturalist, although he must not expect to be so
fortunate in his companions as I have been, to take all
chances, and to start, on travels by land if possible, if other-
wise, on a long voyage. He may feel assured, he will meet
with no difficulties or dangers, excepting in rare cases, nearly
so bad as he beforehand anticipates. In a moral point of
view, the effect ought to be, to teach him good-humoured
patience, freedom from selfishness, the habit of acting for
himself, and of making the best of every occurrence. In
short, he ought to partake of the characteristic qualities of
most sailors. Travelling ought also to teach him distrust;
but at the same time he will discover, how many truly kind-
hearted people there are, with whom he never before had,
or ever again will have any further communication, who
yet are ready to offer him the most disinterested assistance.
